The intelligent machine learns by itself from scratch using a trial-and-error approach that is reinforced by the reward of a score in the game. This is fundamentally different to previous game-playing “intelligent” computers, the researchers said.

The system of software algorithms is called Deep Q-network and has learned to play 49 classic Atari games such as Space Invaders and Breakout, but only with the help of information about the pixels on a screen and the scoring method.

The researchers behind the development said that it represents a breakthrough in artificial intelligence capable of learning from

New Russian Air-to-Air Missiles Will Field Almost Perfect Accuracy

Russia’s new T-50-variant Fifth Generation Fighter Aircraft (PAK FA) may feature the most accurate air-to-air missile system ever devised. The new system specifically targets the ability of skilled fighter pilots to engage in violent maneuvers to break missile locks in older-generation technology, based on a radar system held within the nose of the missile.

The new missile, pegged the K-77M, was described by Russia Today as an “absolute killer.” It notes that what sets the K-77M’s technology apart from its counterparts is the implementation of a “active phased array antenna (APAA)” which essentially solves the lock-on problem by addressing the radar’s “field of view” problem.  Previously, this limitation allowed pilots to swing their jets out of the range of a tailing guided missile when in close proximity, evading the scope of the radar’s view. The K-77M essentially implements a solution similar to the Raytheon’s Patriot surface-to-air (SAM) missile system, according to Russia Today.

Russia Today explains the technology in more detail: “An active phased array antenna consists of Full Article Here

An Onslaught of Biometrics?

Yes­ter­day, I was stand­ing in a check­out line at the gro­cery store sur­rounded by the usual items — a wide selec­tion of can­dies, celebrity mag­a­zines, and diet tips. Of course, one of the mag­a­zines was adver­tis­ing a com­bi­na­tion of two themes: a celebrity diet. I’ve always found these diets incred­i­bly silly, not because the advice is nec­es­sar­ily bad, but because the whole mat­ter of eco­nomic incen­tives is left out of the equation.

Celebri­ties don’t stay in shape thanks to spe­cial tech­niques or a superb per­sonal trainer. Rather, the profit motive does most of the work. In order to con­tinue mak­ing mil­lions every year, celebri­ties must stay incred­i­bly fit. If each of our read­ers were offered a mil­lion dol­lars per year to stay in shape, we’d all see the pounds falling off rapidly. The aver­age per­son sim­ply doesn’t have the same incen­tives as actors and actresses. Most Hol­ly­wood denizens don’t stay fit because of fab­u­lous diets — they have a very pow­er­ful mon­e­tary incen­tive that keeps them on those diets. The rest of us can cheat; we don’t have a movie shoot com­ing up in a few months.

But isn’t health and a long life enough of an incen­tive? Yes and no. As a doc­tor friend of Read more…
