In recent years, deep reinforcement learning has developed rapidly. Many deep reinforcement learning models are applied in various simple game environments. There are many applications with environments far more complex than simple games. Hence, the performance of the deep reinforcement learning model should be improved in many aspects. In this paper, we explore the effect of fast training and enhancing spatio-temporal representation in deep reinforcement learning model. For the former aspect, we propose to utilize the depthwise separable Convolutional Neural Network (CNN) to accelerate deep reinforcement learning model. For the latter aspect, we introduce the convolutional long short-term memory network (ConvLSTM) to improve the expression ability of spatio-temporal feature. We verify the models in the experiments of StarCraft II [1], a game strategy with a complex environment for reinforcement learning. All of the agents learn a certain level game strategy, such as ‘siege’ and ‘searching’. The experimental results show that depth-wise separable CNN has a good effect in shortening training time and the ConvLSTM has better spatial and temporal feature representation ability to improve the performance of the agents.
