NNUE, (ƎUИИ Efficiently Updatable Neural Networks)
a Neural Network architecture intended to replace the evaluation of Shogi, chess and other board game playing alpha-beta searchers running on a CPU.
NNUE was introduced in 2018 by Yu Nasu [3],
and was used in Shogi adaptations of Stockfish such as YaneuraOu [4],
and Kristallweizen [5], apparently with AlphaZero strength [6].
Contents
Stockfish NNUE
As reported by Henk Drost [7], Nodchip incorporated NNUE into the chess playing Stockfish 10 as a proof of concept. Stockfish NNUE was born, and in summer 2020 the computer chess community bursts out enthusiastically due to its rapidly raising playing strength with different networks trained using a mixture of supervised and reinforcement learning methods - despite the approximately halved search speed, becoming stronger than its original [8].
NNUE Engines
see Category:NNUE
Being tempted by the success of Stockfish NNUE and attracted by how easy the method and small the code is, many engine developers have started testing and applying NNUE. For quick trials and evaluating before going into serious development, some of them borrowed and/or rewrote NNUE code and use networks from Stockfish NNUE. Most of them reported positive results, such as David Carteau with Orion [9], Ehsan Rashid with DON [10], various Stockfish derivatives by Michael Byrne [11], and Volodymyr Shcherbyna with Igel [12] using the Night Nurse NNUE net by Dietrich Kappe [13]. In October 2020, Daniel Shawul added NNUE support a la CFish into his egbbdll probing library [14] [15].
NN Structure
The neural network consists of four layers, W1 through W4. The input layer W1 is heavily overparametrized, feeding in the board representation for various king configurations. The efficiency of the net is due to incremental update of W1 in make and unmake move, where only a fraction of its neurons need to be recalculated. The remaining three layers with 32x2x256, 32x32 and 32x1 weights are computational less expensive, best calculated using appropriate SIMD instructions like AVX2 on x86-64, or if available, AVX-512.
