Can We Predict Performance of Large Models across Vision-Language Tasks?

ICML 2025poster

Evaluating large vision-language models (LVLMs) is very expensive, due to high computational cost and the wide variety of tasks. The good news is that if we already have some observed performance scores, we may be able to infer unknown ones. In this study, we propose a new framework for predicting u…

The First to Know: How Token Distributions Reveal Hidden Knowledge in Large Vision-Language Models?

ECCV 2024poster

"Large vision-language models (LVLMs), designed to interpret and respond to human instructions, occasionally generate hallucinated or harmful content due to inappropriate instructions. This study uses linear probing to shed light on the hidden knowledge at the output layers of LVLMs. We demonstrate…

Towards Optimal Feature-Shaping Methods for Out-of-Distribution Detection

ICLR 2024poster

Feature shaping refers to a family of methods that exhibit state-of-the-art performance for out-of-distribution (OOD) detection. These approaches manipulate the feature representation, typically from the penultimate layer of a pre-trained deep learning model, so as to better differentiate between in…
