Peter Navarro slams Federal Reserve: 'playing checkers in a chess world'

FOX News

On Fox Nation's "Maria Bartiromo's Insiders", White House trade adviser Peter Navarro pointed the finger at the Federal Reserve amid concerns of a potential U.S. economic recession. "The problem here, the thing that worries me is that we've got a Federal Reserve playing checkers in a chess world," said Navarro. Despite signs of slowing U.S. job growth and global economic uncertainty, Navarro insists that the U.S. economy is "solid", and he blamed the U.S. central bank for failing to properly react to financial moves made by global actors. "In the world of central banking, the Federal Reserve has to pay very close attention to what the European Central Bank is doing and other central banks. If they lower, we have to lower otherwise we lose exports and we slow our growth," said Navarro, adding that the high cost of borrowing is damaging to the U.S. economy.

Not long ago, Hadoop's technology was supposed to solve all the world's complex data problems. "From the time it went open source in 2007, Hadoop and its related technologies have been profound drivers of the growth of data science." While Hadoop continues to solve some thorny data problems, pundits are now asking "Is Hadoop dead?" It's a sad state of affairs when most organizations have yet to fully understand and take advantage of Hadoop but it is already seen as obsolete โ€“ things are moving awfully fast! In my eighteen years as a data professional, I've experienced many data transformations and technological advances.

"The program can achieve at least a draw against any opponent, playing either the black or white pieces," the researchers say in this week's online edition of the journal Science. "Clearly ... the world is not going to be revolutionized" by this, said Jonathan Schaeffer, chairman of the department of computing science at the University of Alberta. The important thing is the approach, he said. In the past, game-playing programs have used rules of thumb -- which are right most of the time, he said -- to make decisions. "What we've done is show that you can take non-trivial problems, very large problems, and you can do the same kind of reasoning with perfection.


Computers Solve Checkers—It's a Draw

And now, after putting dozens of computers to work night and day for 18 years--jump, jump, jump--he says he has solved the game--king me!. "The starting position, assuming no side makes a mistake, is a draw," he says. Schaeffer's proof, described today in Science (and freely available here for others to verify), would make checkers the most complex game yet solved by machines, beating out the checker-stacking game Connect Four in difficulty by a factor of a million. "It's a milestone," says Murray Campbell, a computer scientist at IBM's T. J. Watson Research Center in Hawthorne, N.Y., and co-inventor of the chess program Deep Blue. "He's stretched the state of the art." Although technological limits prohibit analyzing each of the 500 billion billion possible arrangements that may appear on an eight-by-eight checkerboard, Schaeffer and his team identified moves that guaranteed the game would end in a draw no matter how tough the competition.

The new edition of this extraordinary book depicts the creation of the world champion checkers computer program, Chinook. In only two years, Chinook had become a worthy opponent to the world champion, and within four years had defeated all the world's top human players. Jonathan Schaeffer, the originator and leader of the Chinook team, details the mistakes and technical problems made and the lessons learned in the continuous effort to improve Chinook's performance, revealing the human factor behind the program's design. The development of Chinook begins in 1988 as an innocent question asked over lunch and is followed to the final match against then world champion, Marion Tinsley, and ultimately to its recent triumph, solving checkers. Schaeffer's unwaveringly honest narrative features new anecdotes, updated material and technology descriptions, and additional photos and figures, providing an engrossing account of an obsessive quest to achieve perfection in computer checkers.

You will be playing Chinook with the 6 piece databases enabled (i.e. Chinook will have perfect knowledge for all positions with 6 or fewer pieces on the board). You may select one of three levels - novice, amateur, or intermediate. The amount of CPU time used by Chinook increases for each level. After submitting your move, Chinook should respond within a minute or so.

Attention everyone playing checkers at a park, in grade school, or on the massive rug at Cracker Barrel: You can take your pieces and go home. After five thousand years of game play, checkers has been solved. Researchers at the University of Alberta led by Jonathan Schaeffer have created an unbeatable checkers program called Chinook. "There isn't a human alive today that can ever win a game anymore against the full program," Schaeffer says--although he does leave open the possibility that a person could eke out a draw in the unlikely event that she played a perfect game. Not only is Chinook unbeatable, but it has run through every possible move and every possible board configuration, so it will never, ever be surprised.


A Fintech Filter for Artificial Intelligence in 2017 - Finovate

#artificialintelligence

In what The New York Times is calling The Great AI Awakening and Forbes has dubbed The Year of AI, 2017 is shaping up to be obsessively focused on artificial intelligence, a field that has been around for awhile (remember playing checkers against a computer?) Because the technology has finally reached its tipping point, AI, and its close relative machine learning, have taken a variety of industries by storm, bringing self-driving Ubers to the streets of San Francisco (and then carting them away); robotic vacuum cleaners to dirty household floors; and natural language processing to chat bots and IVR communications. With AI already embedded into these industries, it's easy to find examples of how the technology is shaping fintech. Below are eight areas of fintech into which AI has made inroads. Each area is ranked and rated (out of 5 stars) based on how it is currently influenced by AI and based on AI's potential to add value.


CHINOOK The World Man-Machine Checkers Champion

AI Magazine

In 1992, the seemingly unbeatable World Checker Champion Marion Tinsley defended his title against the computer program CHINOOK. After an intense, tightly contested match, Tinsley fought back from behind to win the match by scoring four wins to CHINOOK's two, with 33 draws. This match was the first time in history that a human world champion defended his title against a computer. This article reports on the progress of the checkers (8 3 8 draughts) program CHINOOK since 1992. Two years of research and development on the program culminated in a rematch with Tinsley in August 1994. In this match, after six games (all draws), Tinsley withdrew from the match and relinquished the world championship title to CHINOOK,citing health concerns. CHINOOK has since defended its title in two subsequent matches. It is the first time in history that a computer has won a human-world championship.
