When Does Memory Help Multi-Trajectory Inference for Tool-Use LLM Agents?

Xinzhe Li, Yaguang Tao

Multi-trajectory inference for tool-use LLM agents - generating multiple reasoning attempts and selecting among them - benefits from transferring knowledge across attempts so that…

LiTS: A Modular Framework for LLM Tree Search

Xinzhe Li, Yaguang Tao

LiTS is a modular Python framework for LLM reasoning via tree search. It decomposes tree search into three reusable components (Policy, Transition, and RewardModel) that plug into…

Chain-in-Tree: Back to Sequential Reasoning in LLM Tree Search

Xinzhe Li

Test-time scaling improves large language models (LLMs) on long-horizon reasoning tasks by allocating more compute at inference. LLM inference via tree search (LITS) achieves stron…

GRAMMAR: Grounded and Modular Methodology for Assessment of Closed-Domain Retrieval-Augmented Language Model

Xinzhe Li, Ming Liu, Shang Gao

Retrieval-Augmented Generation (RAG) systems are widely used across various industries for querying closed-domain and in-house knowledge bases. However, evaluating these systems pr…
