Abstract

Learning to process visual input for Deep Reinforcement Learning is challenging and training a neural network with nothing else but a sparse and delayed reward signal seems rather inappropriate. In this work, Deep Q-Networks are leveraged by several unsupervised machine learning methods that provide additional information for the training of the feature extraction stage to find a well suited representation of the input data. The influence of convolutional filters that were pretrained on a supervised classification task, a Convolutional Autoencoder and Slow Feature Analysis are investigated in an end-to-end architecture. Experiments are performed on five ViZDoom environments. We found that the unsupervised methods boost Deep Q-Networks significantly depending on the underlying task the agent has to fulfill. While pretrained filters improve object detection tasks, we find that Convolutional Autoencoders leverage navigation and orientation tasks. Combining these two approaches leads to an agent that performs well on all tested environments.
