Our work shows how a relatively simple and efficient feature extraction method, which counter-intuitively does not use reconstruction error for training, can effectively extract meaningful features from a range of different games. learning. (read more), Ranked #1 on Experiments are allotted a mere 100 generations, which averages to 2 to 3 hours of run time on our reference machine. Tom Schaul, Tobias Glasmachers, and Jürgen Schmidhuber. playing atari. Giuseppe Cuccu, Matthew Luciw, Jürgen Schmidhuber, and Faustino Gomez. Add a This selection is the result of the following filtering steps: (i) games available through the OpenAI Gym; (ii) games with the same observation resolution of [210,160] (simply for implementation purposes); (iii) games not involving 3D perspective (to simplify the feature extractor). have demonstrated the power of combining deep neural networks with Watkins Q learning. Improving exploration in evolution strategies for deep reinforcement The implication is that feature extraction on some Atari games is not as complex as often considered. The model is a convolutional neural network, trained with a variant of Q-learning, whose input is raw pixels and whose output is a value function estimating future … These computational restrictions are extremely tight compared to what is typically used in studies utilizing the ALE framework. ... V., et al. on Atari 2600 Pong. On top of that, the neural network trained for policy approximation is also very small in size, showing that the decision making itself can be done by relatively simple functions. Dario Floreano, Peter Dürr, and Claudio Mattiussi. We kindly thank Somayeh Danafar for her contribution to the discussions which eventually led to the design of the IDVQ and DRSC algorithms. GitHub README.md file to Felipe Petroski Such, Vashisht Madhavan, Edoardo Conti, Joel Lehman, Kenneth O This progress has drawn the attention of cognitive scientists interested in understanding human learning. the Arcade Learning Environment, with no adjustment of the architecture or Under these assumptions, Table 1 presents comparative results over a set of 10 Atari games from the hundreds available on the ALE simulator. Tim Salimans, Jonathan Ho, Xi Chen, Szymon Sidor, and Ilya Sutskever. The experimental setup further highlights the performance gain achieved, and is thus crucial to properly understand the results presented in the next section: All experiments were run on a single machine, using a 32-core Intel(R) Xeon(R) E5-2620 at 2.10GHz, with only 3GB of ram per core (including the Atari simulator and Python wrapper). The evolution can pick up from this point on as if simply resuming, and learn how the new parameters influence the fitness. The update equation for Σ bounds the performance to O(p3) with p number of parameters. Orthogonal matching pursuit: Recursive function approximation with The subfields of Machine Learning called Reinforcement Learning and Deep Learning, when combined have given rise to advanced algorithms which have been successful at reaching or surpassing the human-level performance at playing Atari games to defeating … To offer a more direct comparison, we opted for using the same settings as described above for all games, rather than specializing the parameters for each game. In all runs on all games, the population size is between 18 and 42, again very limited in order to optimize run time on the available hardware. Daan Wierstra Due to this complex layered approach, deep learning … In late 2013, a then little-known company called DeepMind achieved a breakthrough in the world of reinforcement learning: using deep reinforcement learning, they implemented a system that could learn to play many classic Atari games with human (and sometimes superhuman) performance.
