PRiSM: Prototype Regularization for Few-Shot VLMs

Ghassen Baklouti, Omprakash Chakraborty, Jose Dolz +1

Training-free few-shot adaptation methods have gained significant attention recently in the context of Vision-language Models (VLMs). Yet, current benchmarks rely on strong assumpt…

Quantile Adaptive Temperature Scaling for Confidence Calibration

Omprakash Chakraborty, Leo Fillioux, Ismail Ben Ayed +1

Deep neural networks often produce poorly calibrated confidence estimates, overstating their certainty even when predictions are incorrect. Temperature Scaling remains the most wid…

Are Online Skill and Memory Modules Always Worth Their Tokens? A Budget-Constrained Study of Web Agents

Sina Hajimiri, Masih Aminbeidokhti, Jose Dolz +4

Online web agents often augment a base actor with memory, workflow, or skill modules. These modules can improve performance, but they also consume test-time tokens, a cost rarely r…
