Mitigating Tool Overuse for LLMs via Active Knowledge Boundary Probing

RADAR is proposed, an automated framework for knowledge boundary discovery and tool overuse mitigation that globally propagates labels and rewrites conflicts, yielding deployment-aligned decisions with fewer unnecessary tool calls.

Benchmarking and Enhancing Relational Diagrams Reasoning for Multimodal Large Language Models

RD-MCTS, a Monte Carlo Tree Search framework that incorporates diagram-derived structural priors, constraint-consistent state transitions, and inference-time step-level process rewards is proposed, aimed at improving constraint-consistent reasoning on high-difficulty questions.

On the Role of Discriminative Models in Generative Relation Extraction

This work pro-poses the D iscriminative-to-G enerative ( D2G ) framework, which first leverages discriminative models to produce a top-k set of candidate relations, and then integrates this knowledge into generative models via in-context or prompt learning.
