Non-Asymptotic Analysis for Single-Loop (Natural) Actor-Critic with Compatible Function Approximation

Kavli Affiliate: Yi Zhou | First 5 Authors: Yudan Wang, Yue Wang, Yi Zhou, Shaofeng Zou, | Summary: Actor-critic (AC) is a powerful method for learning an optimal policy in reinforcement learning, where the critic uses algorithms, e.g., temporal difference (TD) learning with function approximation, to evaluate the current policy and the actor updates the […]

IXPE observation of PKS 2155-304 reveals the most highly polarized blazar

Kavli Affiliate: Grzegorz Madejski | Summary:We report the X-ray polarization properties of the high-synchrotron-peaked (HSP) blazar PKS 2155$-$304 based on observations with the Imaging X-ray Polarimetry Explorer (IXPE). We observed the source between Oct 27 and Nov 7, 2023. We also conducted an extensive contemporaneous multiwavelength (MW) campaign. We find that during the first half […]

LLM and GNN are Complementary: Distilling LLM for Multimodal Graph Learning

Kavli Affiliate: Xiang Zhang | First 5 Authors: Junjie Xu, Zongyu Wu, Minhua Lin, Xiang Zhang, Suhang Wang | Summary: Recent progress in Graph Neural Networks (GNNs) has greatly enhanced the ability to model complex molecular structures for predicting properties. Nevertheless, molecular data encompasses more than just graph structures, including textual and visual information that […]
