VisInteract: Towards Dynamic Interactive Text-to-Visualization under Imperfect Queries

A new paradigm that reframes Text-to-Vis as interaction-driven intent recovery, and the first benchmark for dynamic interactive Text-to-Vis, featuring controlled imperfection injection, a leakage-controlled User Agent for realistic multi-turn feedback, and dual-perspective (code and chart) automated evaluation are intr...

To Retrieve or To Think? Cross-Boundary Context Evolution for Multi-hop Complex Reasoning

EvoCtx dynamically decides whether the next reasoning transition should cross the current evidence boundary through retrieval or refine the reasoning state within the existing context, and strategically alternates between boundary expansion and intra-boundary trajectory refinement.

RelAgent: a multi-agent solution for molecular relationship grounding

RelAgent decomposes the task into three interpretable stages: entity extraction, substructure localization, and ontology-guided relationship reasoning, and then uses verifier agents to rank structurally plausible candidates to support fine-grained reasoning over molecular substructure.

Do LLMs Truly Generalize in the Molecular Domain? A Perturbation-Based Analysis

A Molecular Perturbation framework that generates syntax-valid structural variants of training molecules under controlled Graph Edit Distance (GED) to probe the manifold regularity of molecular LLMs and suggests that it can partially expand the local trust region and offer a promising direction for stabilizing molecula...
