A Direct Approximation of AIXI Using Logical State Abstractions
Samuel Yang-Zhao, Tianyu Wang, Kee Siong Ng
We propose a practical integration of logical state abstraction with AIXI, a Bayesian optimality notion for reinforcement learning agents, to significantly expand the model class t…

Latent Policies for Adversarial Imitation Learning
Tianyu Wang, Nikhil Karnwal, Nikolay Atanasov
This paper considers learning robot locomotion and manipulation tasks from expert demonstrations. Generative adversarial imitation learning (GAIL) trains a discriminator that disti…

Stochastic Zeroth Order Gradient and Hessian Estimators: Variance Reduction and Refined Bias Bounds
Yasong Feng, Tianyu Wang
We study stochastic zeroth order gradient and Hessian estimators for real-valued functions in . We show that, via taking finite difference along random orthogonal dir…
