Tristan Cazenave, Yen-Chi Chen, Guan-Wei Chen, Shi-Yu Chen, Xian-Dong Chiu, Julien Dehos, Maria Elsa, Qucheng Gong, Hengyuan Hu, Vasil Khalidov, Cheng-Ling Li, Hsin-I Lin, Yu-Jin Lin (+10 others)
2020 arXiv   pre-print
Using these features, we release Polygames, our framework for Zero learning, with its library of games and its checkpoints.  ...  Since DeepMind's AlphaZero, Zero learning quickly became the state-of-the-art method for many board games. It can be improved using a fully convolutional structure (no fully connected layer).  ...  We present Polygames, our open-source zero learning framework available at facebookresearch/polygames.  ...

Deep Learning for General Game Playing with Ludii and Polygames [article]

Dennis J. N. J. Soemers, Vegard Mella, Cameron Browne, Olivier Teytaud
2021 arXiv   pre-print
This paper describes the implementation of a bridge between Ludii and Polygames, which enables Polygames to train and evaluate models for games that are implemented and run through Ludii.  ...  Polygames is a framework with training and search algorithms, which has already produced superhuman players for several board games.  ...  Introduction Self-play training approaches such as those popularised by AlphaGo Zero [27] and AlphaZero [26] , based on combinations of Monte-Carlo tree search (MCTS) [10, 6, 3] and Deep Learning  ...

Minimax Strikes Back [article]

Quentin Cohen-Solal, Tristan Cazenave
2020 arXiv   pre-print
Deep Reinforcement Learning (DRL) reaches a superhuman level of play in many complete information games.  ...  We take another approach to DRL using a Minimax algorithm instead of MCTS and learning only the evaluation of states, not the policy.  ...  Later AlphaGo was redesigned to learn from zero knowledge, leading to AlphaGo Zero and zero learning (Silver et al. 2017) .  ...

Improving Model and Search for Computer Go [article]

Tristan Cazenave
2021 arXiv   pre-print
The standard for Deep Reinforcement Learning in games, following Alpha Zero, is to use residual networks and to increase the depth of the network to get better results.  ...  We also propose a generalization of the PUCT search algorithm that improves on PUCT.  ...  We proposed a generalization of the PUCT bandit of AlphaGo and Alpha Zero so as to make it invariant to the number of descents.  ...

Mobile Networks for Computer Go [article]

Tristan Cazenave
2020 arXiv   pre-print
The architecture of the neural networks used in Deep Reinforcement Learning programs such as Alpha Zero or Polygames has been shown to have a great impact on the performances of the resulting playing engines  ...  This paper proposes to evaluate the interest of Mobile Network for the game of Go using supervised learning as well as the use of a policy head and a value head different from the Alpha Zero heads.  ...  With these improvements AlphaGo Zero was able to learn the game of Go from scratch and surpassed AlphaGo.  ...

Transfer of Fully Convolutional Policy-Value Networks Between Games and Game Variants [article]

Dennis J.N.J. Soemers, Vegard Mella, Eric Piette, Matthew Stephenson, Cameron Browne, Olivier Teytaud
2021 arXiv   pre-print
We use Ludii's large library of games and game variants for extensive transfer learning evaluations, in zero-shot transfer experiments as well as experiments with additional fine-tuning time.  ...  Evaluation of Transfer Learning All transfer learning experiments discussed below used the ResConvConvLogitPoolModelV2 architecture from Polygames (Cazenave et al., 2020) .  ...  Learning to Play Games in Polygames Similar to AlphaZero (Silver et al., 2018) , game-playing agents in Polygames (Cazenave et al., 2020) use a combination of MCTS and deep neural networks (DNNs).  ...

Polygamy in the Marsh Harrier, Circus Aeruginosus: Individual Variation in Hunting Performance and Number of Mates

Wibe Altenburg, Jaap Starkenburg, Serge Daan, Menno Zijlstra
1982 Behaviour  
If variation in hunting performance is indeed largely due to learning, it may be understood why young males tend to refrain from polygamous mating (as in hen harriers; BALFOUR & CAD- BURY, 1979) or from  ...  Of its three alternative specifications (improvement by male attractiveness, territorial quality or parental care), the latter is a likely candidate for the benefits accrueing to the offspring of polygamous  ...

Who Benefits from Production Outcomes? Gendered Production Relations among Climate-Smart Agriculture Technology Users in Rural Ethiopia

Meseret Tsige
2019 Rural Sociology  
However, too little is known about whether the use of agricultural technologies improves gendered production relations, particularly in the Global South.  ...  I also thank anonymous reviewers, whose contributions significantly improved this work. In addition, I am sincerely grateful to all women and men farmers involved in this research.  ...  Interview findings with women in monogamous and polygamous marriages show that bargaining over production outcomes differs in monogamous and polygamous marriages.  ...
