+ | 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]] <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=2&t=74828 Orion 0.7 : NNUE experiment] by [[David Carteau]], [[CCC]], August 19, 2020</ref>, [[Ehsan Rashid]] with [[DON]] <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=2&t=72613&start=320#p856640 Re: New engine releases 2020...Don NNUE 2020?] by supersharp77, [[CCC]], August 19, 2020</ref>, various [[Stockfish#Derivatives|Stockfish derivatives]] by [[Michael Byrne]] <ref>[http://talkchess.com/forum3/viewtopic.php?f=2&t=74825 ... the last shall be first ...] by [[Michael Byrne|MikeB]], [[CCC]], 19 Aug 2020</ref>, and [[Volodymyr Shcherbyna]] with [[Igel]] <ref>[http://talkchess.com/forum3/viewtopic.php?f=2&t=67890&start=10#p856742 Introducing Igel chess engine] by [[Volodymyr Shcherbyna]], [[CCC]], 20 Aug 2020</ref> using the ''Night Nurse'' NNUE net by [[Dietrich Kappe]] <ref>[http://talkchess.com/forum3/viewtopic.php?f=2&t=74837 Night Nurse 0.2] by [[Dietrich Kappe]], [[CCC]], August 19, 2020</ref>. [[Daniel Shawul]] added NNUE support à la [[CFish]] into his [[Scorpio#Bitbases|egbbdll]] probing library of [[Scorpio]] <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=7&t=75400&start=22 Re: Hacking around CFish NNUE] by [[Daniel Shawul]], [[CCC]], October 15, 2020</ref> <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=7&t=75415&start=3 Re: How to scale stockfish NNUE score?] by [[Daniel Shawul]], [[CCC]], October 17, 2020</ref>, making it even easier to use NNUE. The promising engines [[Halogen]] 7 and 8 by [[Kieren Pearson]], and [[Seer]] by [[Connor McMonigle]] came with their own, distinct NNUE implementations, and on November 10, 2020, the commercial [[Dragon by Komodo Chess]] aka [[Komodo]] NNUE appeared <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=2&t=75748 Dragon by Komodo Chess] by [[Larry Kaufman]], [[CCC]], November 10, 2020</ref>, trying to close the gap to Stockfish NNUE. The commercial [[Fat Fritz#Fat Fritz 2|Fat Fritz 2.0]], based on a slightly modified Stockfish 12 using a customized, double sized network, was released by [[ChessBase]] in February 2021. | ||

Home * Learning * Neural Networks * NNUE
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. Inspired by Kunihito Hoki's approach of piece-square tables indexed by king location, and further two-piece locations and side to move as applied in his Shogi engine Bonanza [3], NNUE was introduced in 2018 by Yu Nasu [4], and was used in Shogi adaptations of Stockfish such as YaneuraOu [5],
and Kristallweizen [6], apparently with AlphaZero strength [7].
Stockfish NNUE
As reported by Henk Drost [8], 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 [9], finally responsible for the huge strength improvement of Stockfish 12.
NN Structure
The neural network of Stockfish NNUE 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.

Adoption
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 [11], Ehsan Rashid with DON [12], various Stockfish derivatives by Michael Byrne [13], and Volodymyr Shcherbyna with Igel [14] using the Night Nurse NNUE net by Dietrich Kappe [15]. Daniel Shawul added NNUE support à la CFish into his egbbdll probing library of Scorpio [16] [17], making it even easier to use NNUE. The promising engines Halogen 7 and 8 by Kieren Pearson, and Seer by Connor McMonigle came with their own, distinct NNUE implementations, and on November 10, 2020, the commercial Dragon by Komodo Chess aka Komodo NNUE appeared [18], trying to close the gap to Stockfish NNUE. The commercial Fat Fritz 2.0, based on a slightly modified Stockfish 12 using a customized, double sized network, was released by ChessBase in February 2021.
