About three years ago, DeepMind, a company owned by Google that specializes in AI development, turned its attention to the ancient game of Go. ", The nine variants that were tested by AlphaZero. Under a microscope, a pane of window glass doesn’t look like a collection of orderly molecules, as a crystal would, but... RL Unplugged (RLU) is an offline-RL benchmark suite based on Deepmind... the top 20 AlphaZero-Stockfish games chosen by Grandmaster Matthew Sadler, the top 10 AlphaZero-Elmo games chosen by shogi Master Yoshiharu Habu, 210 AlphaZero-Stockfish chess games and 100 AlphaZero-Elmo shogi games, Towards understanding glasses with graph neural networks, RL Unplugged - An Offline RL Benchmark Suite, Each program ran on the hardware for which they were designed.
