Expert Proximity as Surrogate Rewards for Single Demonstration Imitation Learning

1 code implementation1 Feb 2024 Chia-Cheng Chiang, Li-Cheng Lan, Wei-Fang Sun, Chien Feng, Cho-Jui Hsieh, Chun-Yi Lee

In this paper, we focus on single-demonstration imitation learning (IL), a practical approach for real-world applications where obtaining numerous expert demonstrations is costly or infeasible.

A Unified Framework for Factorizing Distributional Value Functions for Multi-Agent Reinforcement Learning

1 code implementation4 Jun 2023 Wei-Fang Sun, Cheng-Kuang Lee, Simon See, Chun-Yi Lee

In fully cooperative multi-agent reinforcement learning (MARL) settings, environments are highly stochastic due to the partial observability of each agent and the continuously changing policies of other agents.

On Investigating the Conservative Property of Score-Based Generative Models

1 code implementation26 Sep 2022 Chen-Hao Chao, Wei-Fang Sun, Bo-Wun Cheng, Chun-Yi Lee

In addition, we show that USBMs' inability to preserve the property of conservativeness may lead to degraded performance in practice.

Denoising Likelihood Score Matching for Conditional Score-based Data Generation

2 code implementations ICLR 2022 Chen-Hao Chao, Wei-Fang Sun, Bo-Wun Cheng, Yi-Chen Lo, Chia-Che Chang, Yu-Lun Liu, Yu-Lin Chang, Chia-Ping Chen, Chun-Yi Lee

These methods facilitate the training procedure of conditional score models, as a mixture of scores can be separately estimated using a score model and a classifier.
