Autor: Chen Chaohui, Peng Jiarong, Chen Tianyuan

Publikováno v: Special Matrices, Vol 10, Iss 1, Pp 56-66 (2021)

Recently, the extremal problem of the spectral radius in the class of complements of trees, unicyclic graphs, bicyclic graphs and tricyclic graphs had been studied widely. In this paper, we extend the largest ordering of Aα -spectral radius among al

Preference-Guided Reinforcement Learning for Efficient Exploration

Autor: Wang, Guojian, Wu, Faguo, Zhang, Xiao, Chen, Tianyuan, Chen, Xuyang, Zhao, Lin

In this paper, we investigate preference-based reinforcement learning (PbRL) that allows reinforcement learning (RL) agents to learn from human feedback. This is particularly valuable when defining a fine-grain reward function is not feasible. Howeve

Policy Optimization with Smooth Guidance Learned from State-Only Demonstrations

Autor: Wang, Guojian, Wu, Faguo, Zhang, Xiao, Chen, Tianyuan

The sparsity of reward feedback remains a challenging problem in online deep reinforcement learning (DRL). Previous approaches have utilized offline demonstrations to achieve impressive results in multiple hard tasks. However, these approaches place
