AI System learned to master Rubik’s Cube in 44 hours

Meet DeepCube, an artificially intelligent system that’s as good at playing the Rubik’s Cube as the best human master solvers. Incredibly, the system learned to dominate the classic 3D puzzle in just 44 hours and without any human intervention.

“A generally intelligent agent must be able to teach itself how to solve problems in complex domains with minimal human supervision,” write the authors of the new paper, published online at the arXiv preprint server. Indeed, if we’re ever going to achieve a general, human-like machine intelligence, we’ll have to develop systems that can learn and then apply those learnings to real-world applications…

On the surface, the Rubik’s Cube may seem simple, but it offers a staggering number of possibilities. A 3x3x3 cube features a total “state space” of 43,252,003,274,489,856,000 combinations (that’s 43 quintillion), but only one state space matters — that magic moment when all six sides of the cube are the same color. Many different strategies, or algorithms, exist for solving the cube. It took its inventor, Erno Rubik, an entire month to devise the first of these algorithms…

RTFA. Interesting stuff – and you may as well get used to the topic whether you’re ready or not. Your next job interview might be with an entity built on systems like this. 🙂

United States of Amnesia

❝ “The United States of Amnesia.” That’s what Gore Vidal once called us. We remember what we find it convenient to remember and forget everything else. That forgetfulness especially applies to the history of others. How could their past, way back when, have any meaning for us today? Well, it just might. Take the European conflagration of 1914 to 1918, for example…

❝…in Europe, a hundred years ago, war had become politically purposeless. Yet the leaders of the world’s principal powers — including, by 1917, U.S. president Woodrow Wilson — could conceive of no alternative but to try harder, even as the seat of Western civilization became a charnel house…

❝…similarities between the Great War as it unspooled and our own not-in-the-least-great war(s) deserve consideration. Today, as then, strategy — that is, the principled use of power to achieve the larger interests of the state — has ceased to exist. Indeed, war has become an excuse for ignoring the absence of strategy…

❝ Congressional midterm elections are just months away and another presidential election already looms. Who will be the political leader with the courage and presence of mind to declare, “Enough! Stop this madness!” Man or woman, straight or gay, black, brown or white, that person will deserve the nation’s gratitude and the support of the electorate.

Until that occurs, however, the American penchant for war will stretch on toward infinity. No doubt Saudi and Israeli leaders will cheer, Europeans who remember their Great War will scratch their heads in wonder, and the Chinese will laugh themselves silly. Meanwhile, issues of genuinely strategic importance — climate change offers one obvious example — will continue to be treated like an afterthought.

As for the gravy train, it will roll on.

RTFA. The military-industrial complex President Eisenhower warned of – lives better than a top-shelf Wall Street hedge fund manager. Politicians roll over easy-peasy – rotund from pockets stuffed with their share of the proceeds.
