Process-Supervised Reinforcement Learning for Interactive Multimodal Tool-Use Agents

2025 · arXiv (Cornell University)

Effective interactive tool use requires agents to master Tool Integrated Reasoning (TIR): a complex process involving multi-turn planning and long-context dialogue management. To train agents for this dynamic process, particularly in multi-modal contexts, we introduce …

Multi-hop Reading Comprehension across Multiple Documents by Reasoning over Heterogeneous Graphs

2019

Multi-hop reading comprehension (RC) across documents poses new challenge over single-document RC because it requires reasoning over multiple documents to reach the final answer. In this paper, we propose a new model to tackle the …
