Foundation models struggle with cross-dataset face attack detection

By PulseAugur Editorial · [1 sources] ·

A new study published on arXiv investigates the effectiveness of foundation models (FMs) for face presentation attack detection (PAD). The research found that while LoRA-based adaptation can achieve low intra-dataset error rates, it significantly struggles with cross-dataset generalization. This suggests that the pretrained representations and the adaptation dataset itself are more critical for generalization than lightweight adaptation strategies like LoRA. The study evaluated 32 different FMs, noting that zero-shot prompting performed poorly across various model families. AI

IMPACT Highlights limitations in current foundation model adaptation techniques for real-world generalization in security applications.

    LoRA-based Adaptation Alone Is Not Enough: Understanding the Limits of Foundation Models for Face Presentation Attack Detection

    arXiv:2608.09633v1 Announce Type: cross Abstract: Face presentation attack detection (PAD) aims to reliably detect a wide range of presentation attacks. While PAD methods achieve strong performance within individual datasets, their performance degrades under cross-dataset evaluat…
