Representations of Domains via CF-approximation Spaces

no code implementations19 Nov 2022 Guojun Wu, Luoshan Xu

It is proved that the family of CF-closed sets in a CF-approximation space endowed with set-inclusion order is a continuous domain and that every continuous domain is isomorphic to the family of CF-closed sets of some CF-approximation space endowed with set-inclusion order.

SBO-RNN: Reformulating Recurrent Neural Networks via Stochastic Bilevel Optimization

no code implementations NeurIPS 2021 Ziming Zhang, Yun Yue, Guojun Wu, Yanhua Li, Haichong Zhang

In this paper we consider the training stability of recurrent neural networks (RNNs) and propose a family of RNNs, namely SBO-RNN, that can be formulated using stochastic bilevel optimization (SBO).

Reward Advancement: Transforming Policy under Maximum Causal Entropy Principle

no code implementations11 Jul 2019 Guojun Wu, Yanhua Li, Zhenming Liu, Jie Bao, Yu Zheng, Jieping Ye, Jun Luo

In this paper, we define and investigate a general reward trans-formation problem (namely, reward advancement): Recovering the range of additional reward functions that transform the agent's policy from original policy to a predefined target policy under MCE principle.
