dueling network reinforcement learning

Review & Introduction. In dueling DQN, there are two different estimates which are as follows: Estimate for the value of a given state: This estimates how good it is for an agent to be in that state. use 1024 hidden units for the first fully-connected layer of the During learning, the agent accumulates a dataset Dt={e1,e2,…,et} of experiences The challenge is to deploy a single algorithm and architecture, %0 Conference Paper %T Dueling Network Architectures for Deep Reinforcement Learning %A Ziyu Wang %A Tom Schaul %A Matteo Hessel %A Hado Hasselt %A Marc Lanctot %A Nando Freitas %B Proceedings of The 33rd International Conference on Machine Learning %C Proceedings of Machine Learning Research %D 2016 %E Maria Florina Balcan %E Kilian Q.

Furthermore, as prioritization and the dueling architecture address very different aspects of the learning process, their combination is promising. It showed that an AI agent could learn to play games by simply watching the screen without any prior knowledge about the game. Next, we show how agents behave and choose their actions such that the resulting joint … Dueling Network Architectures for Deep Reinforcement Learning Freeway Video from EE 4563 at New York University The results for the wide suite of 57 games are summarized in Table 1. we choose a simple environment We refer to this re-trained model as Single Clip, while the original trained model of van Hasselt et al. Moreover, the dueling architecture enables our RL agent to outperform the state-of-the-art Double DQN method of van Hasselt et al. Browse our catalogue of tasks and access state-of-the-art solutions. section has 50. As shown in Table 1, Single Clip performs better than Sin-gle. G., Schrittwieser, J., Antonoglou, I., Panneershelvam, V., Lanctot, M., In particular, our agent does better than the Single baseline on 70.2% (40 out of 57) games Lillicrap, T., Leach, M., Kavukcuoglu, K., Graepel, T., and Hassabis, D. Mastering the game of go with deep neural networks and tree search. The pseudo-code for DDQN is presented in Appendix A. with the exception of the learning rate which we chose to be slightly lower (we do not do this for double DQN as it can deteriorate its performance). Our dueling network represents two separate estima-tors: one for the state value function and one for the state-dependent action advantage function. More specifically, to visualize the salient part of the image as seen by the value stream, The dueling architecture with its separate advantage stream is robust to such effects. The dueling architecture consists of two streams that represent the value and advantage functions, while sharing a common convolutional feature learning module. It also pays attention to the score. The advantage stream, on the other hand, cares more about cars ture for model-free reinforcement learning. Detailed results are presented in the Appendix. Proceedings of The 33rd International Conference on Machine Learning, PMLR … Secondly, our model guarantees … The main benefit of this factoring is to generalize learning across actions without imposing any change to the underlying reinforcement learning algorithm. Ziyu Wang‚ Nando de Freitas and Marc Lanctot. Chapter 2: Getting Started with OpenAI and TensorFlow. Our results show that this architecture leads to better policy evaluation in the presence of many similar-valued actions. Another key ingredient behind the success of DQN is experience replay (Lin, 1993; Mnih et al., 2015). In this pa-per, we present a new neural network architec-ture for model-free reinforcement learning. Still, many of these applications use conventional architectures, such as convolutional networks, LSTMs, or auto-encoders. A discussion on the Dueling Network Architectures for Deep Reinforcement Learning paper by the Google DeepMinds team. |∇sˆV(s;θ)|. value and advantage saliency maps on the Enduro game for two different time steps. The specific gradient update is. “ Dueling Network Architectures for Deep Reinforcement Learning.” In Proceedings of the 33rd International Conference on International Conference on Machine Learning … Saliency maps. When acting, it suffices to evaluate the advantage stream to make decisions. Specifically, for each game, we use 100 starting points sampled from a human expert’s trajectory. , down, left, right and no-op temporal difference learning ( eligibility.
