Research Paper Overview
HOLA: Enhancing Audio-visual Deepfake Detection via Hierarchical Contextual Aggregations and Efficient Pre-training
Summary
HOLA proposes a two-stage video-level deepfake detection framework leveraging large-scale audio-visual self-supervised pre-training on 1.81M samples. It integrates iterative-aware cross-modal learning, hierarchical contextual modeling with gated aggregations, and a pyramid-like refiner for semantic enhancement. The method uses pseudo supervised signal injection and achieves state-of-the-art results, ranking first in the 2025 1M-Deepfakes Detection Challenge.
