Graph-Aware Reinforcement Learning for Reusable Prompt Compression in Black-Box LLMs

This paper proposes a task-aware graph reinforcement learning framework that compresses reusable reasoning contexts in black-box LLMs by training a lightweight policy to make extractive keep-or-drop decisions on graph-structured reasoning units, achieving significant input-cost savings while preserving reasoning accuracy.

An SO(3)-equivariant reciprocal space neural potential for long-range interactions

The paper introduces EquiEwald, a novel SO(3)-equivariant neural interatomic potential that extends Ewald summation to reciprocal space to effectively capture long-range electrostatic and polarization interactions while preserving orientation-dependent information, thereby significantly improving accuracy and data efficiency in machine-learning models for periodic and aperiodic systems.

Knowledge-Constrained Reasoner: Attempting to Enable LLMs to Parse Knowledge for Question Answering

This paper introduces the Knowledge-Constrained Reasoner, a novel approach that employs a single alignment phase to internalize essential reasoning capabilities into Large Language Models, thereby ensuring the rigorous and correct utilization of external knowledge for question answering and bridging the reliability of traditional expert systems with the flexibility of non-parametric continuous learning.
