Black Friday sales online top $1 billion for first time

SAN FRANCISCO (Reuters) - Black Friday retail sales online this year topped $1 billion for the first time ever as more consumers used the Internet do their early holiday shopping, comScore Inc said on Sunday.

Online sales jumped 26 percent on Black Friday to $1.04 billion from sales of $816 million on the corresponding day last year, according to comScore data.

Amazon.com was the most-visited retail website on Black Friday, and it also posted the highest year-over-year visitor growth rate among the top five retailers. Wal-Mart Stores Inc's website was second, followed by sites run by Best Buy Co., Target Corp. and Apple Inc, comScore noted.

Digital content and subscriptions, including e-books, digital music and video, was the fastest-growing retail category online, with sales up 29 percent versus Black Friday last year, according to comScore data.

E-commerce accounts for less than 10 percent of consumer spending in the United States. However, it is growing much faster than bricks-and-mortar retail as shoppers are lured by low prices, convenience, faster shipping and wide selection.

ShopperTrak, which counts foot traffic in physical retail stores, estimated Black Friday sales at $11.2 billion, down 1.8 percent from the same day last year.

"Online has been around 9 percent of total holiday sales, but it could breach 10 percent for the first time this season," said Scot Wingo, chief executive of ChannelAdvisor, which helps merchants sell more on websites, including Amazon.com and eBay.com.

ComScore expects online retail spending to rise 17 percent to $43.4 billion through the whole holiday season. That is above the 15 percent increase last season and ahead of the retail industry's expectation for a 4.1 percent increase in overall spending this holiday.

CYBER MONDAY OUTLOOK

It's not clear yet whether strong Black Friday sales online will weaken growth on Cyber Monday, which has been the biggest e-commerce day in the United States in recent years.

"Cyber Monday will be a big day, but not as much of a big day as it has been in the past," said Mia Shernoff, executive vice president for Chase Paymentech, a payment-processing unit of J.P. Morgan Chase & Co.. "Faster broadband Internet connections in the office used to drive this. But now many consumers have faster connections at home and smart phones and tablets - they don't have to wait."

ComScore Chairman Gian Fulgoni said Cyber Monday online sales may reach $1.5 billion this year. That would be up 20 percent from the corresponding day last year - slower year-over-year growth than Thanksgiving and Black Friday.

More than 129 million Americans plan to shop online on Cyber Monday, up from almost 123 million on the same day last year, according to a survey conducted in recent days for the National Retail Federation.

The group also expects 85 percent of retailers to have a special promotion for Cyber Monday.

Amazon, the world's largest Internet retailer, will launch Cyber Monday deals at midnight on Sunday. The company is planning a limited time Cyber Monday promotion for its 7 inch Kindle Fire tablet, offering it at $129 instead of the regular $159, a spokesman said on Sunday.

MOBILE SHOPPING GROWTH

A big source of online shopping growth this holiday season has come from increased use of smart phones, which let people buy online even when they are in physical stores, and by tablet computers, which have spurred more online shopping in the evenings, Wingo and others said.

Mobile devices accounted for 26 percent of visits to retail websites and 16 percent of purchases on Black Friday. That was up from 18.1 percent and 10.3 percent, respectively, on the same day last year, according to International Business Machines, which analyzes online traffic and transactions from 500 U.S. retailers.

More than 20 million shoppers plan to use mobile devices on Cyber Monday, up from 17.8 million a year ago, the NRF said.

Hard-fought victory assures Irish spot in national title game

LOS ANGELES — Deliverance arrived on a crisp southern California night, welcomed in a frenzy of leaps and hugs and arms wind-milling helmets and cathartic screams. Notre Dame waited decades for this, all right, the end to the interminable search for its long-lost promise. It just needed to climb to the top of college football to find it.

The Irish will play for a national championship in January, inextricably No. 1 and 12-0 after a 22-13 victory over USC before 93,607 witnesses Saturday night at Los Angeles Memorial Coliseum, a sparkling moment of rapture in the City of Angels. Whether Notre Dame is back maybe isn't the point right now. It's that the Irish have arrived.

"We had a dream," linebacker Manti Te'o said, "and we put in the work to make sure that dream came true."

It was a grinding, imperfect but relentless effort Saturday to get there, and maybe there couldn't be any other way. Everett Golson, the redshirt freshman quarterback, cramped up but cut loose for 217 yards passing and was mistake-free. Theo Riddick, the senior tailback who was a slot receiver at this time last year, stampeded to 146 yards and a score.

And the Heisman hopeful, Te'o, picked off another pass and helped spearhead another adrenalized, fourth-quarter goal-line stand that stomped out USC's last hope and created a save-the-date for Jan. 7. There Notre Dame will play in the BCS title game, almost assuredly against the winner of the SEC, becoming the most galvanizing foil yet to that league's dominance.

"The way it's set up, only two teams can play for a national championship," Irish coach Brian Kelly said. "It feels great that you have that opportunity."

One game now, to look upon everyone else from the summit for the first time since 1988.

"Ecstatic," Irish safety Zeke Motta said. "There's no other feeling like it that I could have ever imagined. You think about the hard work and the competing that we did in the offseason, and to witness it pay off, and to be in this position we're in right now, there's no other feeling like it."

There were other, substantially less exultant feelings swirling in the same stadium tunnel a scant four years ago. Athletic director Jack Swarbrick could laugh about that Saturday night: About being pinned against a wall to discuss the downward spiral of the Charlie Weis era then, and being cornered to talk about a head-spinning revival now.

A year after that utter demolition by USC in 2008, Swarbrick made his coaching change and brought in Kelly. He brought in his program-builder. He thought it was the perfect fit. He also thought it would take longer than this.

"I gotta tell you, I always thought it was next year," Swarbrick said. "From Day 1, I thought it was next year. So it's cool. It's cool to be ahead of schedule."

In fact, maybe the only guy not taken aback was the guy responsible for it all.

"You get this far into it, and now you start to look up and go, oh, we're 11-0 — you want to finish it off," Kelly said.

"It's easy to say well, yeah, I'm surprised. But when you go in that locker room and you're around the guys I'm around, you're not surprised. What they've done, the commitment they've made, they've done everything I've asked them to do. Everything. So it doesn't surprise me anymore."

Notre Dame had USC where it wanted the Trojans early, on-heels and tested, on the spot to demonstrate any mettle or desire at the end of a season gone wrong and going nowhere. The Irish thundered to a 10-0 first-quarter lead, first scoring on a Kyle Brindza 27-yard field goal and then a Riddick 9-yard score.

If this was the last hurdle to the BCS title game, it appeared knee-high. But USC showed it could be resolute, swiftly moving to an 11-yard Robert Woods touchdown reception to reignite some drama. From there, it was field goal after field goal after field goal for both sides, a constant thrust and parry, all the way to a Brindza 33-yarder that made it a 19-10 lead entering the fourth quarter.

"We understood that it was going to be a dogfight, and that's what it was," Te'o said.

Then Notre Dame watched in glee as USC coach Lane Kiffin began exacting self-torture. First came the pre-snap timeout that might have wiped out a touchdown catch, only to watch the ensuing pass sail out of the end zone.

And after the fifth Brindza field goal created a two-score cushion with six minutes left, the pain became excruciating. A 53-yard Marqise Lee reception after a long kickoff return set up a goal-to-go situation for the Trojans. Two pass interference penalties put them on the 1-yard line. They ran once. They ran again. They ran again. Then they threw an incomplete pass.

Notre Dame had made its stand, everyone exploding off the sideline and into celebration.

"If you have followed us all year, that's how we play," Kelly said. "We come up big defensively at some time during the game. We did that again."

All that remained were 21/2 minutes to burn. Irish fans in attendance counted down the Coliseum clock, as if it was New Year's Eve.

And then the celebration began, wild and joyous, for a date decades in the making. Players bobbed and chanted in front of the fans. Te'o grabbed Kelly in the tunnel in a spontaneous embrace, telling his coach he loved him.

Notre Dame will play for a national title. A moment so many waited for, and never saw coming.

"I haven't really grasped the whole situation," Riddick said, sitting on a table in a Coliseum tunnel. "What can I say? We're going to Miami."

‘Gangnam Style’ most watched YouTube video ever

SEOUL, South Korea (AP) — South Korean rapper PSY‘s “Gangnam Style” has become YouTube’s most viewed video of all time.

YouTube says in a posting on its Trends blog that “Gangnam Style” had been viewed 805 million times as of Saturday afternoon, surpassing Justin Bieber‘s “Baby,” which has had 803 million views.

The blog says the “velocity of popularity for PSY’s outlandish video is unprecedented.”

PSY’s video featuring his horse-riding dance was posted on YouTube in July, while “Baby” was uploaded in February 2010.

PSY’s video has become a global sensation, with many people around the world mimicking his “Gangnam Style” dance. In their October meeting, U.N. Secretary-General Ban Ki-moon, a South Korean, joked that he had to relinquish his title as “the most famous Korean,” and tried a few of PSY’s dance moves.

Rosenthal: Big Ten getting too big for its own good?

There's a lesson the empire builders at Big Ten Conference headquarters in Park Ridge would do well to heed if they can be convinced to stop peering out to the distant horizon:

Growth through acquisition is fraught with peril.

"In the business world you acquire new companies and you have to deal with different corporate cultures, different priorities and so forth," Robert Arnott, chairman of Research Affiliates LLC, an investment firm, said in an interview. "Merging them is often very messy and often fails. Here you're merging two teams into an existing conference and it creates risks. … Even college football teams have different cultures, different ways of thinking about how to win and different standards."

There undoubtedly was a logic behind each acquisition as the old Sears sought to expand and diversify its corporate profile. By the time the Chicago-area company's portfolio grew to include Allstate insurance, Coldwell Banker real estate and Dean Witter Reynolds stock brokerage, it was clear the increase in size was in no way matched by an increase in strength.

Rather than an all-powerful Colossus astride many sectors at once, it was reduced to an unfocused blob, bereft of identity, covering plenty of ground but hardly standing tall. Years after shedding its far-flung holdings, Sears has yet to regain its muscle, mojo or market share.

"It's hard to find a better example of a company that lost its mission and focus in the quest for growth," Arnott said.

"(Growth) may be partly a defensive move. It may be ego driven. In the corporate arena, you certainly see that in spades," he said. "When growth is through acquisition, you have to figure out what the real motivation is. Is it synergy, the most overused word in the finance community, or is it ego?"

Adding the University of Maryland and New Jersey's Rutgers University in 2014 will push the Big Ten to 14 schools and far beyond the Midwestern territory for which it's known. But doing so may not achieve what its backers envision.

Rather than spread the conference's brand, it may merely dilute it. The fit may be corrosive, not cohesive.

There is a school of thought that this is but the latest evidence that the Big Ten is not about athletics, academics or even the Midwest. Instead, it is just a television network, the schools content providers and student-athletes talent.

As it is, the overall TV payout is said to give each of the 12 current Big Ten schools about $21 million per year. They point to the Big Ten's lucrative deals with ESPN and its own eponymous cable network, a partnership with News Corp. They note that public schools Rutgers and Maryland are near enough to New York, Baltimore and Washington, D.C., to drive a better bargain with cable carriers.

To Big Ten Commissioner Jim Delany, a New Jersey native, the addition is more the result of a paradigm shift that has redrawn the college sports map over the past decade. Some conferences splinter. Others seize new turf. The result: Idaho's Boise State football team is poised to join the Big East Conference next year.

"Institutions that get together for academics or athletics have got to be cognizant that they are competing for students, they are competing for student athletes, they are competing for research dollars," Delany told reporters.

"When you see a Southern conference in the Midwest or you see a Southern conference in the Plains states or whether you see other conferences in the Midwest or Northeast, it impacts your recruitment. ... It impacts everything you do," he said. "At a certain point you get to a tipping point. The paradigm has shifted, and you decide on a strategy to basically position yourself for the next decade or half-century."

Big has always meant more than 10 in the Big Ten, an intercollegiate entity formed by seven Midwestern universities that now boasts 12 with the bookends of Penn State and Nebraska added in 1990 and last year, respectively. Last week's announcement of adding schools 13 and 14 was just a reminder that the conference has only had 10 member schools for 70 of its 116 years and won't again for the foreseeable future.

Rutgers President Robert Barchi said his school looked "forward as much to the collaboration and interaction we're going to have as institutions as we do to what I know will be really outstanding competition on our field of play."

But make no mistake, the Big Ten was born out of sports, specifically football. A seven-school 1896 meeting at Chicago's Palmer House had Northwestern among those still stinging from a scathing Harper's Weekly critique of college sports abuses, the Tribune reported at the time.

A prohibition on allowing scholarship and fellowship students to compete was shot down. But "a move towards the coordination of Faculty committees" in terms of standards and enforcement passed and the precursor to the Big Ten was born.

Along the way, the conference has added member schools and come to recognize that the Big Ten's image has much to say about how those institutions are perceived. Scandals already are no stranger to the Big Ten. But whether you play in a stadium or on Wall Street, the bigger one gets, the bigger target one becomes.

"Whoever's biggest draws scrutiny," said Arnott, co-author of a research paper, "The Winners Curse: Too Big to Succeed." "That means politicians, regulators, the general public generally don't root for the biggest. They look to take them down a notch, so it's harder to succeed as the largest. It's also harder to move the dial and move from success to success as you get really big."

Everyone talks about becoming too big to fail, but there's also too big to scale, companies that are unable to capitalize on the efficiencies of their increased size ostensibly because they are so big that they cannot be managed adequately.

"People talk about economies of scale. There are also vast diseconomies of scale, mostly in bureaucracies," Arnott said. "The more people you have involved, the more people you have who feel they have to have their views reflected in whatever's done. So you wind up with innovation by committee."

That's deadly. That's why companies break up, citing the need to get smaller so they can grow.

"If you break up companies into operating entities that are more nimble," Arnott said, "the opportunities to grow are no longer hamstrung by centralized bureaucracies that have to pursue synergies that don't exist."

Size matters in all fields of play. Sometimes smaller is better.

Larry Hagman dies at 81; TV's J.R. Ewing

Fervor for the television show “Dallas” was intense in 1980, when the Queen Mother met actor Larry Hagman and joined the worldwide chorus asking: “Who shot J.R.?”

“Not even for you, ma’am,” replied Hagman, who portrayed villainous oil baron J.R. Ewing at the center of the popular prime-time soap from 1978 until 1991.

An estimated 300 million viewers in 57 countries had seen J.R. get shot by an unseen assailant, a season-ending plot twist that is credited with popularizing the cliffhanger in television series.

Hagman, who became a television star in the 1960s starring in the sitcom “I Dream of Jeannie,” died Friday at a Dallas hospital, said a spokesman for actress Linda Gray, his longtime co-star on “Dallas.” He was 81.

A year ago, Hagman announced his second bout with cancer. He had spoken candidly about decades of drinking that led to cirrhosis of the liver and, in 1995, a life-saving liver transplant.

“He was the pied piper of life and brought joy to everyone he knew,” Gray said in a statement. “He was creative, generous, funny, loving and talented.... an original and lived life to the full.”

For years, he was considered the unofficial mayor of Malibu, where he lived for decades in an oceanfront home. He often led impromptu ragtag parades on the sand while wearing outlandish costumes and flew a flag from his deck that declared “Vita Celebratio Est” — “Life is a celebration.”

As an actor, Hagman came with a serious pedigree. He was the son of Mary Martin, a legendary star of Broadway musicals best known for originating the role of Peter Pan in the 1950s.

On “Dallas,” Hagman's J.R. Ewing was “the man viewers loved to hate,” according to critics, a scheming Texan in a land of plenty. Much of the show's run paralleled the nation's fascination with big money and big business in the 1980s, and the role made him an international star.

“Here is a man born to play villainy,” former Times TV critic Howard Rosenberg wrote soon after the show's debut. “His performance on ‘Dallas’ is a salute to slime.”

A Texas native, Hagman often said he played the character as a composite of “all those good old boys” he had known growing up, “who caught more flies with honey instead of vinegar.”

He approached the role as “a cartoon,” Hagman once said of the role that earned him two Emmy nominations. “It was outrageous comedy to me.”

By his own admission, Hagman drank his way through “Dallas.” Champagne was “his poison” — he would uncork a bottle by 9 a.m. and keep the bubbly flowing all day. He once poured bourbon on his cornflakes.

“The drinking sometimes made it harder to remember lines, but I liked that constant feeling of being mildly loaded,” Hagman said in 1995 in People magazine.

Diagnosed with cirrhosis of the liver during a checkup in 1992, Hagman said he became an instant teetotaler. After developing a cancerous tumor on his liver, he underwent a liver transplant three years later.

“I'm often asked how my liver transplant operation changed my life. Aside from saving it, nothing changed,” he wrote in his 2001 autobiography, “Hello Darlin’.” “It confirmed what I've always tried to do — live my life as fully as possible before the clock runs out.”

When Hagman arrived in Hollywood in the 1960s, he had already appeared in a half-dozen Broadway plays and spent two years on the daytime television soap opera “The Edge of Night.”

From five television pilots, Hagman chose to read for the part of astronaut Tony Nelson on “I Dream of Jeannie.” Created by Sidney Sheldon, the show plugged into the nation’s space mania and owed a creative debt to another hit series, “Bewitched.”

Jeannie was played by Barbara Eden, who complicates the life of uptight Nelson after he aborts a mission on a desert island and unleashes her character — a magical and alluring genie — from a bottle.

‘Dallas’ star Larry Hagman dies in Texas

J.R. Ewing was a business cheat, faithless husband and bottomless well of corruption. Yet with his sparkling grin, Larry Hagman masterfully created the charmingly loathsome oil baron — and coaxed forth a Texas-size gusher of ratings — on television’s long-running and hugely successful nighttime soap, “Dallas.”

Although he first gained fame as nice guy Capt. Tony Nelson on the fluffy 1965-70 NBC comedy “I Dream of Jeannie,” Hagman earned his greatest stardom with J.R. The CBS serial drama about the Ewing family and those in their orbit aired from April 1978 to May 1991, and broke viewing records with its “Who shot J.R.?” 1980 cliffhanger that left unclear if Hagman’s character was dead.

The actor, who returned as J.R. in a new edition of “Dallas” this year, had a long history of health problems and died Friday due to complications from his battle with cancer, his family said.

“Larry was back in his beloved hometown of Dallas, re-enacting the iconic role he loved the most. Larry’s family and closest friends had joined him in Dallas for the Thanksgiving holiday,” the family said in a statement that was provided to The Associated Press by Warner Bros., producer of the show.

The 81-year-old actor was surrounded by friends and family before he passed peacefully, “just as he’d wished for,” the statement said.

Linda Gray, his on-screen wife and later ex-wife in the original series and the sequel, was among those with Hagman in his final moments in a Dallas hospital, said her publicist, Jeffrey Lane.

“He brought joy to everyone he knew. He was creative, generous, funny, loving and talented, and I will miss him enormously. He was an original and lived life to the fullest,” the actress said.

Years before “Dallas,” Hagman had gained TV fame on “I Dream of Jeannie,” in which he played an astronaut whose life is disrupted when he finds a comely genie, portrayed by Barbara Eden, and takes her home to live with him.

Eden recalled late Friday shooting the series’ pilot “in the frigid cold” on a Malibu beach.

“From that day, for five more years, Larry was the center of so many fun, wild and sometimes crazy times. And in retrospect, memorable moments that will remain in my heart forever,” Eden said.

Hagman also starred in two short-lived sitcoms, “The Good Life” (NBC, 1971-72) and “Here We Go Again” (ABC, 1973). His film work included well-regarded performances in “The Group,” ”Harry and Tonto” and “Primary Colors.”

But it was Hagman’s masterful portrayal of J.R. that brought him the most fame. And the “Who shot J.R.?” story twist fueled international speculation and millions of dollars in betting-parlor wagers. It also helped give the series a place in ratings history.

When the answer was revealed in a November 1980 episode, an average 41 million U.S. viewers tuned in to make “Dallas” one of the most-watched entertainment shows of all time, trailing only the “MASH” finale in 1983 with 50 million viewers.

It was J.R.’s sister-in-law, Kristin (Mary Crosby) who plugged him — he had made her pregnant, then threatened to frame her as a prostitute unless she left town — but others had equal motivation.

Hagman played Ewing as a bottomless well of corruption with a charming grin: a business cheat and a faithless husband who tried to get his alcoholic wife, Sue Ellen (Gray), institutionalized.

“I know what I want on J.R.’s tombstone,” Hagman said in 1988. “It should say: ‘Here lies upright citizen J.R. Ewing. This is the only deal he ever lost.’”

On Friday night, Victoria Principal, who co-starred in the original series, recalled Hagman as “bigger than life, on-screen and off. He is unforgettable, and irreplaceable, to millions of fans around the world, and in the hearts of each of us, who was lucky enough to know and love him.”

Ten episodes of the new edition of “Dallas” aired this past summer and proved a hit for TNT. Filming was in progress on the sixth episode of season two, which is set to begin airing Jan. 28, the network said.

There was no immediate comment from Warner or TNT on how the series would deal with Hagman’s loss.

In 2006, he did a guest shot on FX’s drama series “Nip/Tuck,” playing a macho business mogul. He also got new exposure in recent years with the DVD releases of “I Dream of Jeannie” and “Dallas.”

The Fort Worth, Texas, native was the son of singer-actress Mary Martin, who starred in such classics as “South Pacific” and “Peter Pan.” Martin was still in her teens when he was born in 1931 during her marriage to attorney Ben Hagman.

As a youngster, Hagman gained a reputation for mischief-making as he was bumped from one private school to another. He made a stab at New York theater in the early 1950s, then served in the Air Force from 1952-56 in England.

While there, he met and married young Swedish designer Maj Axelsson. The couple had two children, Preston and Heidi, and were longtime residents of the Malibu beach colony that is home to many celebrities.

Hagman returned to acting and found work in the theater and in such TV series as “The U.S. Steel Hour,” ”The Defenders” and “Sea Hunt.” His first continuing role was as lawyer Ed Gibson on the daytime serial “The Edge of Night” (1961-63).

He called his 2001 memoir “Hello Darlin’: Tall (and Absolutely True) Tales about My Life.”

“I didn’t put anything in that I thought was going to hurt someone or compromise them in any way,” he told The Associated Press at the time.

Hagman was diagnosed in 1992 with cirrhosis of the liver and acknowledged that he had drank heavily for years. In 1995, a malignant tumor was discovered on his liver and he underwent a transplant.

After his transplant, he became an advocate for organ donation and volunteered at a hospital to help frightened patients.

“I counsel, encourage, meet them when they come in for their operations, and after,” he said in 1996. “I try to offer some solace, like ‘Don’t be afraid, it will be a little uncomfortable for a brief time, but you’ll be OK.’ “

He also was an anti-smoking activist who took part in “Great American Smoke-Out” campaigns.

Funeral plans were not immediately announced.

“I can honestly say that we’ve lost not just a great actor, not just a television icon, but an element of pure Americana,” Eden said in her statement Friday night. “Goodbye, Larry. There was no one like you before and there will never be anyone like you again.”

Scientists See Advances in Deep Learning, a Part of Artificial Intelligence

Hao Zhang/The New York Times

A voice recognition program translated a speech given by Richard F. Rashid, Microsoft’s top scientist, into Mandarin Chinese.

Using an artificial intelligence technique inspired by theories about how the brain recognizes patterns, technology companies are reporting startling gains in fields as diverse as computer vision, speech recognition and the identification of promising new molecules for designing drugs.

The advances have led to widespread enthusiasm among researchers who design software to perform human activities like seeing, listening and thinking. They offer the promise of machines that converse with humans and perform tasks like driving cars and working in factories, raising the specter of automated robots that could replace human workers.

The technology, called deep learning, has already been put to use in services like Apple’s Siri virtual personal assistant, which is based on Nuance Communications’ speech recognition service, and in Google’s Street View, which uses machine vision to identify specific addresses.

But what is new in recent months is the growing speed and accuracy of deep-learning programs, often called artificial neural networks or just “neural nets” for their resemblance to the neural connections in the brain.

“There has been a number of stunning new results with deep-learning methods,” said Yann LeCun, a computer scientist at New York University who did pioneering research in handwriting recognition at Bell Laboratories. “The kind of jump we are seeing in the accuracy of these systems is very rare indeed.”

Artificial intelligence researchers are acutely aware of the dangers of being overly optimistic. Their field has long been plagued by outbursts of misplaced enthusiasm followed by equally striking declines.

In the 1960s, some computer scientists believed that a workable artificial intelligence system was just 10 years away. In the 1980s, a wave of commercial start-ups collapsed, leading to what some people called the “A.I. winter.”

But recent achievements have impressed a wide spectrum of computer experts. In October, for example, a team of graduate students studying with the University of Toronto computer scientist Geoffrey E. Hinton won the top prize in a contest sponsored by Merck to design software to help find molecules that might lead to new drugs.

From a data set describing the chemical structure of 15 different molecules, they used deep-learning software to determine which molecule was most likely to be an effective drug agent.

The achievement was particularly impressive because the team decided to enter the contest at the last minute and designed its software with no specific knowledge about how the molecules bind to their targets. The students were also working with a relatively small set of data; neural nets typically perform well only with very large ones.

“This is a really breathtaking result because it is the first time that deep learning won, and more significantly it won on a data set that it wouldn’t have been expected to win at,” said Anthony Goldbloom, chief executive and founder of Kaggle, a company that organizes data science competitions, including the Merck contest.

Advances in pattern recognition hold implications not just for drug development but for an array of applications, including marketing and law enforcement. With greater accuracy, for example, marketers can comb large databases of consumer behavior to get more precise information on buying habits. And improvements in facial recognition are likely to make surveillance technology cheaper and more commonplace.

Artificial neural networks, an idea going back to the 1950s, seek to mimic the way the brain absorbs information and learns from it. In recent decades, Dr. Hinton, 64 (a great-great-grandson of the 19th-century mathematician George Boole, whose work in logic is the foundation for modern digital computers), has pioneered powerful new techniques for helping the artificial networks recognize patterns.

Modern artificial neural networks are composed of an array of software components, divided into inputs, hidden layers and outputs. The arrays can be “trained” by repeated exposures to recognize patterns like images or sounds.

These techniques, aided by the growing speed and power of modern computers, have led to rapid improvements in speech recognition, drug discovery and computer vision.

Deep-learning systems have recently outperformed humans in certain limited recognition tests.

Last year, for example, a program created by scientists at the Swiss A. I. Lab at the University of Lugano won a pattern recognition contest by outperforming both competing software systems and a human expert in identifying images in a database of German traffic signs.

The winning program accurately identified 99.46 percent of the images in a set of 50,000; the top score in a group of 32 human participants was 99.22 percent, and the average for the humans was 98.84 percent.

Walmart protests draw crowds, shoppers largely unfazed

Dozens of local workers, and hundreds nationally, took advantage of Black Friday crowds and camera crews at major retailers like Walmart to call for wage increases.

But there was little evidence that the chanting disrupted holiday shoppers.

Steven Restivo, a spokesman for Wal-Mart Stores, said the chain had done its "best Black Friday event ever" despite protests organized by the United Food and Commercial Workers International Union in Chicago and other cities.

At a Walmart in Chicago's Chatham neighborhood on the south side, only one of the store's 500 employees took part in the demonstration, the Bentonville, Ark.-based retailer said. "Almost all the folks you'll see protesting today are not Walmart associates," Restivo said. "I guess you can't believe everything you read in a union press release."

According to the union, protests took place in Miami and Washington, D.C., with additional events planned at Midwestern and Southern stores.

Walmart has so far avoided a union presence, which has become cumbersome for competitors like Jewel-Osco and Dominick's Finer Foods. Those chains have been closing stores as Walmart has expanded locally.

Separately Friday, dozens of members of the Workers Organizing Committee of Chicago and its supporters marched from the Loop to the Magnificent Mile to demand a $15 minimum wage and union contracts for downtown workers. Organized on November 15, the union has about 150 members and has received financial support from Service Employees International Union, Action Now and Stand Up Chicago.

Deborah Sims, marching Friday, said she worked at Macy's for 12 years, eventually making $13 an hour, before losing her job during the recession. She was rehired last holiday season, but at $8.50 an hour, with no benefits.

Sims said she expects retailers to turn to younger, less-experienced workers because "$8.25 an hour is going to look good to them."

Macy's did not respond to a request for comment.

Peter Gill, a spokesman for the Illinois Retail Merchants Association, called the demand for a $15 minimum wage dangerous "because people are out looking for jobs and it's tough in this economy."

He explained that if retailers were forced to nearly double the starting hourly wage, "you're going to have to cut the number of employees."

Black Friday shopping gets an early start in Chicago

After dinner at a Maggiano's restaurant, the Tannehill/Schroeder clan headed over to Sears at Woodfield Mall in search of a 50-inch flat-screen TV for less than $300.

After 10 minutes of waiting in line, they breezed into the store. That's when Terri Schroeder, of Chicago, began to yell. "Hurry, grab a TV," she said to her sister-in-law, Margie Tannehill, of West Chicago. Both women laughed.

As it turns out, the family of eight waited in the wrong line at the wrong door at Sears. Vouchers for the 50-inch TV and other discounted "door-busters" were given out at another entrance, and they missed their chance to snag the coveted TV.

After making their way through the swarming crowd, they found another TV, and both women grabbed it. They settled on a smaller, less expensive 32-inch flat-screen set that at $250 was on sale but not a door-buster that had throngs of shoppers waiting in line at Sears since Thursday afternoon.

"This is not the one we wanted, but we're keeping it," Schroeder said with a giggle.

She joined throngs of shoppers who cut off Thanksgiving celebrations to turn their attention to preparing for the December holiday season, which typically accounts for up to 40 percent of retailers' sales.

Black Friday historically launched the day after Thanksgiving. But in recent years, stores have opened at 4 a.m., then midnight. Last year, retailers created a stir by opening at 10 p.m. Thursday. This year, Wal-Mart upped the ante when it announced plans to open at 8 p.m.

Taryan Sanders and Maurice Boston, both 25, were among those hanging out at the Wal-Mart in Humboldt Park, waiting for the 8 p.m. round of door-busters.

With a cart already filled with playthings like a Monster High doll, toy puppy and scooter (they'd been at the store since 4 p.m.), the couple stationed themselves near a pallet of Nerf gun sets that would go on sale for $10 each, items they eyed for Sanders' younger brothers.

"Gotta get the door-busters for my daughter and two brothers," Sanders said. "I already ate, and I'm out ready to get my shop on!"

This year, holiday spending is expected to rise 4.1 percent, according to the National Retail Federation. Last year, more than 24 percent of Black Friday shoppers were out before midnight, and nearly 39 percent of shoppers were in the stores before 5 a.m.

A recent survey from the consulting firm Deloitte shows that Chicago-area consumers plan to spend about 10 percent more on gifts this year, shelling out an average of $450. Most also expect the national economy to pick up in 2013 — their most positive outlook since 2009.

Beyond early Thanksgiving openings, retailers have also vied to outdo one another by offering Black Friday-esque discounts — in stores and online — nearly a week early.

"First blood is everything," said Wendy Liebmann, CEO and chief shopper at WSL Strategic Retail, a New York-based consumer behavior research firm. "This is really the first year where we've seen a vast majority of retailers decide that Thanksgiving Day is no longer sacrosanct."

Retailers are pulling out all the stops, from offering gift cards as incentives to shoppers who buy higher-priced items to touting deeper-than-ever discounts on popular items such as televisions and tablets. They'll send coupons to shoppers' phones, and many will promise to match rivals' prices.

"The earlier you can get people to open their wallets, the better," Liebmann said. "The uncertainty of life is such that you don't know what people will spend throughout the (holiday) season. So get 'em when you can."

With Black Friday bleeding into Thursday, the type of shopper prowling for good deals was expected to change, industry watchers said.

Mothers and families typically hit the stores Friday. But this year, retail watchers say men were expected to make a strong showing Thursday night. Big-spending millennials might also be inclined to soak up the partylike atmosphere.

The earlier hours open a window to "appeal to a wider array of customers," said Ben Arnold, director of industry analysis at the Port Washington, N.Y.-based research firm NPD Group.

Some things stay the same, though. As in years past, shoppers are angling to get more bang for their buck. Flat-screen TVs have always been big Black Friday sellers, but this year, they are expected to be larger and cheaper. TVs and laptops, annual best-sellers, are expected to hit a new price low, experts say.

Wal-Mart greeted Thursday night shoppers with deeply discounted TVs, video game consoles and Blu-ray players. At Sears, shoppers were met with on-sale tablet computers, washer and dryer sets, refrigerators and more TVs, among other items.

To prepare for the crowds, retailers have bolstered employee ranks and stepped up training. They have also staggered door-buster deals.

Toys R Us, which opened at 8 p.m. Thursday, distributed tickets to shoppers lined up for door-buster deals such as a 16-gigabyte iPod accompanied by $50 in gift cards, to avoid a "mad rush," CEO Jerry Storch told the Tribune in an interview. "It de-stresses the crowd," he said.

At electronics seller Best Buy, which opened at midnight, store managers have been giving staff crash courses in customer service and product knowledge, said Mitchell Zelasko, sales manager at the retailer's Bucktown location. The chain has hired more than 20,000 employees nationwide for its stores, distribution centers and customer service centers to support the holiday rush.

Locally, Best Buy planned to boost security for the shopping kickoff Friday, keep employees well-fed and in the store by ordering food and bringing in off-duty Chicago police officers to help keep order.

"Things can change very quickly in a mob situation," Zelasko said. "We keep things under control and we keep it fun."

The New Old Age Blog: Home Health Care Help by the Hour

Here is a bright idea that ought to spread: You call your home care agency and say you will need your mother’s aide for the normal two hours on Monday and Wednesday, but for just half an hour (to drive her to a doctor’s office) on Tuesday, then 90 minutes on Thursday. And the agency says, “Sure.”

It sounds logical to hire someone to help — with bathing, dressing, errands, meal preparation, medication reminders – for only as many hours as an older adult needs assistance. But it is actually unusual for companies to offer such flexibility.

The majority of agencies require a four-hour minimum. Having to spend $80  — the national average cost for home care is $21 an hour — if you only need $40 worth of help is a big barrier for families trying to keep their elderly relatives living at home longer. A few agencies allow you to hire for fewer than four hours, but at higher rates.

But Mission Healthcare in San Diego, Calif., a three-year-old agency that began with Medicare-certified skilled home nursing and hospice care, expanded to general home care this summer and decided that clients should be able to specify how much help they want – in 15-minute increments — and will pay for.

“We’ll come for as long as they need us to,” said Mark Kimsey, one of Mission’s four directors. “In one hour, a well-trained caregiver can get the client bathed and dressed, prepare three meals and have them organized for the day.” (I have to think that is a speedy caregiver with a not-too-frail client, but still … )

Can Mission, which charges $19 to $20 an hour, actually make money this way? Though overall the agency serves 1,100 clients, its fledgling home care business is still small: 30 aides caring for just 60 clients. The aides can get benefits if they work enough hours, a bonus for them and for consumers (better employees, lower turnover), but an additional cost for the company.

The directors say they are profitable already, and that the approach will succeed because more people will like the flexibility and potential savings, and sign up. It is also true, let’s acknowledge, that a person who can get by with an hour or two a day for now may well need more help eventually, a boost for Mission’s bottom line.

Competitors are no doubt watching to see if this works. I’m curious, too, to see if the policy catches on. “Consumers can change the marketplace if they want to,” Mr. Kimsey said. It would be nice to think that is true.

Would you use this kind of hourly service, if it were available?
