From Patching to Pruning Visual Computation in Vision Language Models

Rahul Chowdhury, Timothy A Rupprecht, Xuan Shen +3

Vision language models (VLMs) incur substantial inference cost because every visual token is processed by the attention and MLP projections of every decoder layer, even when token-…

Mechanistic Interpretability of Structure-Aware Numerical Reasoning in LLaMA 3.1 8B

Rahul Chowdhury, Timothy A Rupprecht, Senhao Cao +5

Recent work has shown that large language models (LLMs) exhibit strong numerical sequence modeling capabilities and show promise in time-series prediction. While LLMs display in-co…

ScAle: Attention Head Scaling as a Minimal Adapter for Spatial Reasoning in Vision Language Models

Rahul Chowdhury, Timothy A Rupprecht, Xuan Shen +2

Spatial reasoning remains a persistent challenge for many vision language models (VLMs), and improving it typically requires fine-tuning with substantial additional parameters. Our…

Human Cognition in Machines: A Unified Perspective of World Models

Timothy Rupprecht, Pu Zhao, Amir Taherin +20

This report of world models distinguishes prior works by the cognitive functions they innovate. Many works claim an almost human-like cognitive capability in their world models. To…
