Note that in general the game score may depend on the whole prior sequence of actions and observations; feedback about an action may only be received after many thousands of time-steps have elapsed. approximation. The most successful approaches are trained directly from the raw inputs, using lightweight updates based on stochastic gradient descent. We instead use an architecture in which there is a separate output unit for each possible action, and only the state representation is an input to the neural network. Learning to control agents directly from high-dimensional sensory inputs like vision and speech is one of the long-standing challenges of reinforcement learning (RL). 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 rewards. Since our evaluation metric, as suggested by [3], is the total reward the agent collects in an episode or game averaged over a number of games, we periodically compute it during training. Both averaged reward plots are indeed quite noisy, giving one the impression that the learning algorithm is not making steady progress. Deep neural networks have been used to estimate the environment E; restricted Boltzmann machines have been used to estimate the value function [21]; or the policy [9]. The final input representation is obtained by cropping an 84×84 region of the image that roughly captures the playing area. In addition, the divergence issues with Q-learning have been partially addressed by gradient temporal-difference methods. Since running the emulator forward for one step requires much less computation than having the agent select an action, this technique allows the agent to play roughly k times more games without significantly increasing the runtime. Neural Networks (IJCNN), The 2010 International Joint Reinforcement learning for robots using neural networks. large-vocabulary speech recognition. Sketch-based linear value function approximation. Playing Atari with Deep Reinforcement Learning An explanatory tutorial assembled by: Liang Gong Liang Gong, Electric Engineering & Computer Science, University of California, Berkeley. Such value iteration algorithms converge to the optimal action-value function, Qi→Q∗ as i→∞ [23]. Rather than computing the full expectations in the above gradient, it is often computationally expedient to optimise the loss function by stochastic gradient descent. The raw frames are preprocessed by first converting their RGB representation to gray-scale and down-sampling it to a 110×84 image. More recently, there has been a revival of interest in combining deep learning with reinforcement learning. Marc G. Bellemare, Joel Veness, and Michael Bowling. This is based on the following intuition: if the optimal value Q∗(s′,a′) of the sequence s′ at the next time-step was known for all possible actions a′, then the optimal strategy is to select the action a′ maximising the expected value of r+γQ∗(s′,a′). More precisely, the agent sees and selects actions on every kth frame instead of every frame, and its last action is repeated on skipped frames.

In contrast, our agents only receive the raw RGB screenshots as input and must learn to detect objects on their own. Subsequently, results were improved by using a larger number of features, and using tug-of-war hashing to randomly project the features into a lower-dimensional space [2]. We present the first deep learning model to successfully learn control policies directly from high-dimensional sensory input using reinforcement learning. During the inner loop of the algorithm, we apply Q-learning updates, or minibatch updates, to samples of experience, e∼D, drawn at random from the pool of stored samples. Alex Krizhevsky, Ilya Sutskever, and Geoff Hinton. Investigating contingency awareness using atari 2600 games. Follow. Convergent Temporal-Difference Learning with Arbitrary Smooth This method relies heavily on finding a deterministic sequence of states that represents a successful exploit. Clearly, the performance of such systems heavily relies on the quality of the feature representation. Since the scale of scores varies greatly from game to game, we fixed all positive rewards to be 1 and all negative rewards to be −1, leaving 0 rewards unchanged. This suggests that, despite lacking any theoretical convergence guarantees, our method is able to train large neural networks using a reinforcement learning signal and stochastic gradient descent in a stable manner. 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 rewards. Subsequently, the majority of work in reinforcement learning focused on linear function approximators with better convergence guarantees [25]. While the whole process may sound like a like bunch of scientists having fun at work, playing Atari with deep reinforcement learning is a great way to evaluate a learning model. We define the optimal action-value function Q∗(s,a) as the maximum expected return achievable by following any strategy, after seeing some sequence s and then taking some action a, Q∗(s,a)=maxπE[Rt|st=s,at=a,π], where π is a policy mapping sequences to actions (or distributions over actions). Pierre Sermanet, Koray Kavukcuoglu, Soumith Chintala, and Yann LeCun. Proc. Since Q maps history-action pairs to scalar estimates of their Q-value, the history and the action have been used as inputs to the neural network by some previous approaches [20, 12]. So far, we have performed experiments on seven popular ATARI games – Beam Rider, Breakout, Enduro, Pong, Q*bert, Seaquest, Space Invaders. Kevin Jarrett, Koray Kavukcuoglu, Marc’Aurelio Ranzato, and Yann LeCun. We used k=3 to make the lasers visible and this change was the only difference in hyperparameter values between any of the games. In 2013 the Deepmind team invented an algorithm called deep Q-learning.It learns to play Atari 2600 games using only the input from the screen.Following a call by OpenAI, we adapted this method to deal with a situation where the playing agent is given not the screen, but rather the RAM state of the Atari machine. The use of the Atari 2600 emulator as a reinforcement learning platform was introduced by [3], who applied standard reinforcement learning algorithms with linear function approximation and generic visual features. This paper introduces a novel method for learning how to play the most difficult Atari 2600 games from the Arcade Learning Environment using deep reinforcement learning. Problem Statement •Build a single agent that can learn to play any of the 7 atari 2600 games. Playing Atari with Deep Reinforcement Learning Volodymyr Mnih, Koray Kavukcuoglu, David Silver, Alex Graves, Ioannis Antonoglou, Daan Wierstra, Martin Riedmiller. The network was not provided with any game-specific information or hand-designed visual features, and was not privy to the internal state of the emulator; it learned from nothing but the video input, the reward and terminal signals, and the set of possible actions—just as a human player would. Our work was accepted to the Computer Games Workshop accompanying the … agents. RL algorithms, on the other hand, must be able to learn from a scalar reward signal that is frequently sparse, noisy and delayed. The first hidden layer convolves 16 8×8 filters with stride 4 with the input image and applies a rectifier nonlinearity [10, 18]. So far the network has outperformed all previous RL algorithms on six of the seven games we have attempted and surpassed an expert human player on three of them. Machine Learning (ICML 2013). Playing Atari with Deep Reinforcement Learning Volodymyr Mnih Koray Kavukcuoglu David Silver Alex Graves Ioannis Antonoglou Daan Wierstra Martin Riedmiller DeepMind Technologies {vlad,koray,david,alex.graves,ioannis,daan,martin.riedmiller} @ deepmind.com Abstract We present the first deep learning model to successfully learn control … Actor-critic reinforcement learning with energy-based policies. Note that both of these methods incorporate significant prior knowledge about the visual problem by using background subtraction and treating each of the 128 colors as a separate channel. In the reinforcement learning community this is typically a linear function approximator, but sometimes a non-linear function approximator is used instead, such as a neural network. 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 rewards. Koray Kavukcuoglu     Instead, it is common to use a function approximator to estimate the action-value function, Q(s,a;θ)≈Q∗(s,a). First, each step of experience is potentially used in many weight updates, which allows for greater data efficiency. Furthermore the network architecture and all hyperparameters used for training were kept constant across the games. If the weights are updated after every time-step, and the expectations are replaced by single samples from the behaviour distribution ρ and the emulator E respectively, then we arrive at the familiar Q-learning algorithm [26]. For the experiments in this paper, the function ϕ from algorithm 1 applies this preprocessing to the last 4 frames of a history and stacks them to produce the input to the Q-function. However, these methods have not yet been extended to nonlinear control. Advances in Neural Information Processing Systems 22. In contrast, our algorithm is evaluated on ϵ-greedy control sequences, and must therefore generalize across a wide variety of possible situations. 0 Report inappropriate Github: kevinchn/atari-dqn We present the first deep learning model to successfully learn control policies directly from high-dimensional sensory input using reinforcement learning. A Q-network can be trained by minimising a sequence of loss functions Li(θi) that changes at each iteration i. where yi=Es′∼E[r+γmaxa′Q(s′,a′;θi−1)|s,a] is the target for iteration i and ρ(s,a) is a probability distribution over sequences s and actions a that we refer to as the behaviour distribution. The action is passed to the emulator and modifies its internal state and the game score. In contrast our approach applies reinforcement learning end-to-end, directly from the visual inputs; as a result it may learn features that are directly relevant to discriminating action-values. The behavior policy during training was ϵ-greedy with ϵ annealed linearly from 1 to 0.1 over the first million frames, and fixed at 0.1 thereafter. Pedestrian detection with unsupervised multi-stage feature learning. The human performance is the median reward achieved after around two hours of playing each game. •Input: –210 X 60 RGB video at 60hz (or 60 frames per … The parameters from the previous iteration θi−1 are held fixed when optimising the loss function Li(θi).

Deep Reinforcement Learning combines the modern Deep Learning approach to Reinforcement Learning. DeepMind Technologies. predicted Q for these states. For the learned methods, we follow the evaluation strategy used in Bellemare et al. 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 rewards. The two rightmost plots in figure 2 show that average predicted Q increases much more smoothly than the average total reward obtained by the agent and plotting the same metrics on the other five games produces similarly smooth curves. 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 rewards. Toward off-policy learning control with function approximation. The model learned to play seven Atari 2600 games and the results showed that the algorithm outperformed all the previous approaches. We trained for a total of 10 million frames and used a replay memory of one million most recent frames. We apply our method to seven Atari 2600 games from the Arcade Learning Environment, with no adjustment of the architecture or learning algorithm. Audio, Speech, and Language Processing, IEEE Transactions on. Proc. We present the first deep learning model to successfully learn control policies directly from high-dimensional sensory input using reinforcement learning. These methods utilise a range of neural network architectures, including convolutional networks, multilayer perceptrons, restricted Boltzmann machines and recurrent neural networks, and have exploited both supervised and unsupervised learning. George E. Dahl, Dong Yu, Li Deng, and Alex Acero. Since this approach was able to outperform the best human backgammon players 20 years ago, it is natural to wonder whether two decades of hardware improvements, coupled with modern deep neural network architectures and scalable RL algorithms might produce significant progress. In contrast to TD-Gammon and similar online approaches, we utilize a technique known as experience replay [13] where we store the agent’s experiences at each time-step, et=(st,at,rt,st+1) in a data-set D=e1,...,eN, pooled over many episodes into a replay memory. This architecture updates the parameters of a network that estimates the value function, directly from on-policy samples of experience, st,at,rt,st+1,at+1, drawn from the algorithm’s interactions with the environment (or by self-play, in the case of backgammon). 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 rewards. Playing Atari with Deep Reinforcement Learning 1. Marc G Bellemare, Yavar Naddaf, Joel Veness, and Michael Bowling. In addition to seeing relatively smooth improvement to predicted Q during training we did not experience any divergence issues in any of our experiments. The first five rows of table 1 show the per-game average scores on all games. 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 rewards. Function Approximation. This paper introduced a new deep learning model for reinforcement learning, and demonstrated its ability to master difficult control policies for Atari 2600 computer games, using only raw pixels as input. The deep learning model, created by DeepMind, consisted of a CNN trained with a variant of Q-learning. We use the same network architecture, learning algorithm and hyperparameters settings across all seven games, showing that our approach is robust enough to work on a variety of games without incorporating game-specific information. To alleviate the problems of correlated data and non-stationary distributions, we use an experience replay mechanism [13] which randomly samples previous transitions, and thereby smooths the training distribution over many past behaviors. On a more sobering note, if someone had a problem understanding the … Playing Atari Breakout Game with Reinforcement Learning ( Deep Q Learning ) Overview. In addition it receives a reward rt representing the change in game score. The HNeat Best score reflects the results obtained by using a hand-engineered object detector algorithm that outputs the locations and types of objects on the Atari screen. A neuro-evolution approach to general atari game playing. neural reinforcement learning method. We present the first deep learning model to successfully learn control policies directly from high-dimensional sensory input using reinforcement learning. The main advantage of this type of architecture is the ability to compute Q-values for all possible actions in a given state with only a single forward pass through the network. There are several possible ways of parameterizing Q using a neural network. We make the standard assumption that future rewards are discounted by a factor of γ per time-step, and define the future discounted return at time t as Rt=∑Tt′=tγt′−trt′, where T Conference on. Playing Atari with Deep Reinforcement Learning Yunguan Fu 1 Introduction Withinthedomainofreinforcementlearning(RL),oneofthelong-standingchallengesislearn- The paper describes a system that combines deep learning methods and rein-forcement learning in order to create a system that is able to learn how to play simple TD-gammon used a model-free reinforcement learning algorithm similar to Q-learning, and approximated the value function using a multi-layer perceptron with one hidden layer111In fact TD-Gammon approximated the state value function V(s) rather than the action-value function Q(s,a), and learnt on-policy directly from the self-play games. This approach is in some respects limited since the memory buffer does not differentiate important transitions and always overwrites with recent transitions due to the finite memory size N. Similarly, the uniform sampling gives equal importance to all transitions in the replay memory. Ioannis Antonoglou, {vlad,koray,david,alex.graves,ioannis,daan,martin.riedmiller} @ deepmind.com. Matthew Hausknecht, Risto Miikkulainen, and Peter Stone. When trained repeatedly against deterministic sequences using the emulator’s reset facility, these strategies were able to exploit design flaws in several Atari games. The emulator’s internal state is not observed by the agent; instead it observes an image xt∈Rd from the emulator, which is a vector of raw pixel values representing the current screen. Reinforcement learning with factored states and actions. Firstly, most successful deep learning applications to date have required large amounts of hand-labelled training data. Our approach (labeled DQN) outperforms the other learning methods by a substantial margin on all seven games despite incorporating almost no prior knowledge about the inputs. Recognition (CVPR 2009). It seems natural to ask whether similar techniques could also be beneficial for RL with sensory data. (Part 0: Intro to RL) Finally we get to implement some code! 1 Volodymyr Mnih, Koray Kavukcuoglu, David Silver, Alex Graves, Ioannis Antonoglou, Daan Wierstra, and Martin Riedmiller Differentiating the loss function with respect to the weights we arrive at the following gradient. Transcript. Hamid Maei, Csaba Szepesvari, Shalabh Bhatnagar, Doina Precup, David Silver, Figure 3 demonstrates that our method is able to learn how the value function evolves for a reasonably complex sequence of events. Tesauro’s TD-Gammon architecture provides a starting point for such an approach. In practice, the behaviour distribution is often selected by an ϵ-greedy strategy that follows the greedy strategy with probability 1−ϵ and selects a random action with probability ϵ. Experiments We report two sets of results for this method. At each time-step the agent selects an action at from the set of legal game actions, A={1,…,K}. Abstract: We present the first deep learning model to successfully learn control policies directly from high-dimensional sensory input using reinforcement learning. Playing Atari with Deep Reinforcement Learning. Another issue is that most deep learning algorithms assume the data samples to be independent, while in reinforcement learning one typically encounters sequences of highly correlated states. The agent then fires a torpedo at the enemy and the predicted value peaks as the torpedo is about to hit the enemy (point B). CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We present the first deep learning model to successfully learn control policies di-rectly from high-dimensional sensory input using reinforcement learning. A video of a Breakout playing robot can be found on Youtube, as well as a video of a Enduro playing robot. In practice, this basic approach is totally impractical, because the action-value function is estimated separately for each sequence, without any generalisation. The outputs correspond to the predicted Q-values of the individual action for the input state. NFQ optimises the sequence of loss functions in Equation 2, using the RPROP algorithm to update the parameters of the Q-network. We find that it outperforms all previous approaches on six of the games and surpasses a human expert on three of them. This led to a widespread belief that the TD-gammon approach was a special case that only worked in backgammon, perhaps because the stochasticity in the dice rolls helps explore the state space and also makes the value function particularly smooth [19]. Proceedings of the 12th International Conference on Machine Note that when learning by experience replay, it is necessary to learn off-policy (because our current parameters are different to those used to generate the sample), which motivates the choice of Q-learning. Nicolas Heess, David Silver, and Yee Whye Teh. Installation Dependencies: We consider tasks in which an agent interacts with an environment E, in this case the Atari emulator, in a sequence of actions, observations and rewards. We collect a fixed set of states by running a random policy before training starts and track the average of the maximum222The maximum for each state is taken over the possible actions. Finally, we show that our method achieves better performance than an expert human player on Breakout, Enduro and Pong and it achieves close to human performance on Beam Rider. Alex Graves     In this session I will show how you can use OpenAI gym to replicate the paper Playing Atari with Deep Reinforcement Learning. Deep auto-encoder neural networks in reinforcement learning. After performing experience replay, the agent selects and executes an action according to an ϵ-greedy policy. Recent advances in deep learning have made it possible to extract high-level features from raw sensory data, leading to breakthroughs in computer vision [11, 22, 16] and speech recognition [6, 7]. The leftmost two plots in figure 2 show how the average total reward evolves during training on the games Seaquest and Breakout. Our goal is to connect a reinforcement learning algorithm to a deep neural network which operates directly on RGB images and efficiently process training data by using stochastic gradient updates. What is the best multi-stage architecture for object recognition? The average total reward metric tends to be very noisy because small changes to the weights of a policy can lead to large changes in the distribution of states the policy visits . Bayesian learning of recursively factored environments. Note that this algorithm is model-free: it solves the reinforcement learning task directly using samples from the emulator E, without explicitly constructing an estimate of E. It is also off-policy: it learns about the greedy strategy a=maxaQ(s,a;θ), while following a behaviour distribution that ensures adequate exploration of the state space. [Paper Summary] Playing Atari with Deep Reinforcement Learning. European Workshop on Reinforcement Learning. Third, when learning on-policy the current parameters determine the next data sample that the parameters are trained on. Furthermore, it was shown that combining model-free reinforcement learning algorithms such as Q-learning with non-linear function approximators [25], or indeed with off-policy learning [1] could cause the Q-network to diverge. David Silver     ##Deep Reinforcement learning to play Atari games. real time. The final cropping stage is only required because we use the GPU implementation of 2D convolutions from [11], which expects square inputs. NIPS 2014, Human Level Control Through Deep Reinforcement Learning. 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 rewards. The network is trained with a variant of the Q-learning [26] algorithm, with stochastic gradient descent to update the weights. Perhaps the best-known success story of reinforcement learning is TD-gammon, a backgammon-playing program which learnt entirely by reinforcement learning and self-play, and achieved a super-human level of play [24]. approximation. The basic idea behind many reinforcement learning algorithms is to estimate the action-value function, by using the Bellman equation as an iterative update, Qi+1(s,a)=E[r+γmaxa′Qi(s′,a′)|s,a].
