IAPO: Input Attribution-Aware Policy Optimization for Tool Use in Small Multimodal Agents

Yifan Yang, Zhen Zhang, Jiayi Tian +2

This paper investigates reinforcement learning (RL) methods for improving tool-calling capabilities in multimodal small language model (SLM) agents. While existing works have explo…

LoRi: Low-Rank Distillation for Implicit Reasoning

Ryan Solgi, Jiayi Tian, Zheng Zhang

Implicit chain-of-thought (iCoT) methods aim to internalize reasoning in large language models, but often underperform explicit CoT prompting. We empirically find that hidden-state…

Activation-Informed Pareto-Guided Low-Rank Compression for Efficient LLM/VLM

Ryan Solgi, Parsa Madinei, Jiayi Tian +4

Large language models (LLM) and vision-language models (VLM) have achieved state-of-the-art performance, but they impose significant memory and computing challenges in deployment.…

SkipKV: Selective Skipping of KV Generation and Storage for Efficient Inference with Large Reasoning Models

Jiayi Tian, Seyedarmin Azizi, Yequan Zhao +7

Large reasoning models (LRMs) often incur significant key-value (KV) cache overhead, due to their linear growth with the verbose chain-of-thought (CoT) reasoning. This incurs both…

RankGuide: Tensor-Rank-Guided Routing and Steering for Efficient Reasoning

Jiayi Tian, Yupeng Su, Ryan Solgi +2

Large reasoning models (LRMs) enhance problem-solving capabilities by generating explicit multi-step chains of thought (CoT) reasoning; however, they incur substantial inference la…
