Discovering Intrinsic Reward with Contrastive Random Walk

1 code implementation23 Apr 2022 Zixuan Pan, Zihao Wei, Yidong Huang, Aditya Gupta

The aim of this paper is to demonstrate the efficacy of using Contrastive Random Walk as a curiosity method to achieve faster convergence to the optimal policy. Contrastive Random Walk defines the transition matrix of a random walk with the help of neural networks.
