Store the agent's experiences at each time step, Preprocessing done to reduce the input dimensionality, 128 color palette converted to gray-scale representation, Frames are down-sampled from 210 x 160 pixels to 110 x 84 pixels, The final input is obtained by cropping a 84 x 84 pixels region that roughly captures the playing area, This cropping is done in order to use the GPU implementation of 2D convolutions which expects square inputs, The input to the neural network is a 84 x 84 x 4 image (84 x 84 pixels x 4 last frames), The first hidden layer convolves 168 x 8 filters with stride 4 and applies a rectifier nonlinearity, The second hidden layer convolves 324 x 4 filters with stride 2, again followed by a rectifier nonlinearity, The final hidden layer is fully-connected and consists of 256 rectifier units, The output layer is a fully-connected linear layer with a single output for each valid action.

Tom Rochette, Volodymyr Mnih - Playing Atari with Deep Reinforcement Learning (2013), $s_t = x_1, a_1, x_2, a_2, ..., a_{t-1}, x_t$, Reinforcement learning algorithms must be able to learn from a scalar reward signal that is frequently sparse, noisy and delayed, The delay between actions and resulting rewards can be thousands of timesteps apart, Most deep learning algorithms assume the data samples to be independent, while in reinforcement learning we typically encounter sequences of highly correlated states, In reinforcement learning, the data distribution changes as the algorithm learns new behaviors, The paper presents a convolutional neural network that is trained using a variant of the Q-learning algorithm, with stochastic gradient descent to update the weights, The challenge is to learn control policies from raw video data, The goal is to create a single neural network agent that is able to successfully learn to play as many of the games as possible (games for the Atari 2600), Q-network: A neural network function approximator with weight. We propose a conceptually simple and lightweight framework for deep reinforcement learning that uses asynchronous gradient descent for optimization of deep neural network controllers. ; Nair et al., 2015 ) as well as a recurrent agent with additional.
