Google’s AI AlphaZero has shocked the chess world. Leaning on its deep neural networks, and general reinforcement learning algorithm, DeepMind’s AI Alpha Zero learned to play chess well beyond the skill level of master, besting the 2016 top chess engine Stockfish 8 in a 100-game match. Alpha Zero had 28 wins, 72 draws, and 0 losses. Impressive right? And it took just 4 hours of self-play to reach such a proficiency. What the chess world has witnessed from this historic event is, simply put, mind-blowing! AlphaZero vs Magnus Carlsen anyone? 🙂 19-page paper via Cornell University Library https://arxiv.org/abs/1712.01815 https://arxiv.org/pdf/1712.01815.pdf PGN: 1. e4 e5 2. Nf3 Nc6 3.

In 1990 Rodney Brooks authored a paper entitled Elephants Don’t Play Chess – a ground breaking concept that ushered in an alternative view of Artificial Intelligence. Twenty five years later, he is addressing the misconceptions that now surround AI, allaying the media-fueled fears of robots with evil intentions. Hear him in his own words talk about AI, and how Baxter and Sawyer have common sense – the ability to complete tasks, not just motions. Next, see how Rodney Brooks brought Rethink Robotics to life – http://ow.ly/REgEf To view our other videos, including customer stories and how our Baxter and Sawyer robots work, visit the Rethink Robotics video gallery at http://www.rethinkrobotics.com/videos/.

The strongest programs are based on a combination of sophisticated search techniques, domain-specific adaptations, and handcrafted evaluation functions that have been refined by human experts over several decades. In contrast, the AlphaGo Zero program recently achieved superhuman performance in the game of Go, by tabula rasa reinforcement learning from games of self-play. In this paper, we generalise this approach into a single AlphaZero algorithm that can achieve, tabula rasa, superhuman performance in many challenging domains. Starting from random play, and given no domain knowledge except the game rules, AlphaZero achieved within 24 hours a superhuman level of play in the games of chess and shogi (Japanese chess) as well as Go, and convincingly defeated a world-champion program in each case ….
