Improving General Role-Playing Agents via Psychology-Grounded Reasoning and Role-Aware Policy Optimization

Zhenhua Xu, Dongsheng Chen, Jian Li +7

Building general-purpose role-playing agents that faithfully portray any character from a natural-language profile remains challenging. The dominant paradigm -- supervised fine-tun…

Fast radio bursts, magnetars and earthquakes: their "family feud"?

Si-Lu Xu, Yong-Kun Zhang, Pei Wang +24

Fast radio bursts (FRBs) are millisecond-duration cosmic transients whose origin remains elusive. Competing models invoke either earthquake-like processes or flare-like mechanisms.…

MARRS: Masked Autoregressive Unit-based Reaction Synthesis

Yabiao Wang, Shuo Wang, Jiangning Zhang +3

This work aims at a challenging task: human action-reaction synthesis, i.e., generating human reactions conditioned on the action sequence of another person. Currently, autoregress…

TIMotion: Temporal and Interactive Framework for Efficient Human-Human Motion Generation

Yabiao Wang, Shuo Wang, Jiangning Zhang +4

Human-human motion generation is essential for understanding humans as social beings. Current methods fall into two main categories: single-person-based methods and separate modeli…
