An Empirical Study Into What Matters for Calibrating Vision-Language Models

no code implementations12 Feb 2024 Weijie Tu, Weijian Deng, Dylan Campbell, Stephen Gould, Tom Gedeon

Vision--Language Models (VLMs) have emerged as the dominant approach for zero-shot recognition, adept at handling diverse scenarios and significant distribution changes.

Zero-Shot Learning

A Closer Look at the Robustness of Contrastive Language-Image Pre-Training (CLIP)

no code implementations NeurIPS 2023 Weijie Tu, Weijian Deng, Tom Gedeon

Driven by the above, this work comprehensively investigates the safety objectives of CLIP models, specifically focusing on three key properties: resilience to visual factor variations, calibrated uncertainty estimations, and the ability to detect anomalous inputs.

A Bag-of-Prototypes Representation for Dataset-Level Applications

no code implementations CVPR 2023 Weijie Tu, Weijian Deng, Tom Gedeon, Liang Zheng

The former measures how suitable a training set is for a target domain, while the latter studies how challenging a test set is for a learned model.
