A Benchmark for Low-Switching-Cost Reinforcement Learning

no code implementations13 Dec 2021 Shusheng Xu, Yancheng Liang, Yunfei Li, Simon Shaolei Du, Yi Wu

A ubiquitous requirement in many practical reinforcement learning (RL) applications, including medical treatment, recommendation system, education and robotics, is that the deployed policy that actually interacts with the environment cannot change frequently.

Sequence Level Contrastive Learning for Text Summarization

no code implementations8 Sep 2021 Shusheng Xu, Xingxing Zhang, Yi Wu, Furu Wei

In this paper, we propose a contrastive learning model for supervised abstractive text summarization, where we view a document, its gold summary and its model generated summaries as different views of the same mean representation and maximize the similarities between them during training.

Deep Q-Learning with Low Switching Cost

no code implementations1 Jan 2021 Shusheng Xu, Simon Shaolei Du, Yi Wu

We initiate the study on deep reinforcement learning problems that require low switching cost, i. e., small number of policy switches during training.
