The project will contain three parts: State Predictor, Action Predictor and the main program. Each feature can be missing with a certain probability independently. Although the filters themselves are trained on the filter response prediction task - jointly with inferring the action underlying the observed state transition, which avoids the trivial solution - the MSE is comparable to the one achieved here (4x10^-4 vs. 2x10^-3). Also, interesting to note is the difference in learnability for the number of samples the base DQN agent was trained on. All gists Back to GitHub. In model-based deep reinforcement learning, a neural network learns a dynamics model, which predicts the feature values in the next state of the environment, and possibly the associated reward, given the current state and action.

The environments are as follows: Handling partial observability seems to extend well to scenario of partial frame drops, which is also a realistic setting in robotic tasks with faulty sensors. Unlike 2, where a flickering video game is simulated by dropping complete frames randomly, in a sense a more general type of data corruption is considered. While this approach has been shown to work 5, the idea in this experiment is a different one: instead of predicting the low-level pixel values the agent is trained to predict the dynamics of its own convolutional network, i.e. We also investigate how one should learn and plan when the reward function may change or may not be speciﬁed during learning. For example, a number of methods are known for guaranteeing near optimal behavior in a Markov decision process (MDP) by adopting a model-based approach (Kearns & Singh,1998;Brafman & Tennenholtz,2002;Strehl et al.,2009). ∙ KIT ∙ berkeley college ∙ 34 ∙ share Model-based reinforcement learning approaches carry the promise of being data efficient.
