an experimental [[:Category:Open Source|open source chess engine]] by [[Erik Bernhardsson]],
written in [[Python]] as an attempt to [[Deep Learning|learn]] and play chess.
Deep Pink applies [[Negamax|negamax]] [[Alpha-Beta|alpha-beta]] and a [[Neural Networks#Deep|deep neural network]] as [[Evaluation|evaluation function]],
using [https://en.wikipedia.org/wiki/Theano_%28software%29 Theano], [[python-chess]], and [[Sunfish]] <ref>[https://github.com/erikbern/deep-pink erikbern/deep-pink · GitHub]</ref>.
The input representation seems similar to [[Octavius]] with 12x64 nodes, not feeding in [[Side to move|side to move]], [[Castling Rights|castling rights]], and [[En passant|en passant]] target square.
The first hidden layer has 2048 neurons as well. Bernhardsson used a [[GPU]] instance to train the net with 100M games for about four days using [https://en.wikipedia.org/wiki/Stochastic_gradient_descent stochastic gradient descent] with [[Mathematician#YNesterov|Nesterov]] momentum <ref>[https://en.wikipedia.org/wiki/Yurii_Nesterov Yurii Nesterov from Wikipedia]</ref>
