Leela Chess Zero
Gary Linscott initiated and announced the distributed Leela Chess Zero project in early 2018 7. It is an adaption of Gian-Carlo Pascutto's Leela Zero Go project, soon evolving to a strong chess playing entity following the same type of deep learning along with Monte-Carlo tree search (MCTS) techniques of AlphaZero as described in DeepMind's 2017 and 2018 papers 8 9, but using distributed training for the weights of the deep convolutional neural network.
PyTorch NNUE
With the advent of Stockfish NNUE in 2020, Gary Linscott started an implementation of the Stockfish NNUE training in PyTorch 10 11.
