Suppressing Forgery-Specific Shortcuts for Generalizable Deepfake Detection
Researchers propose Shortcut Subspace Suppression (S³), a framework that improves deepfake detection generalization by explicitly identifying and suppressing forgery-method-specific artifacts in neural networks. The approach uses singular value decomposition to isolate shortcut subspaces and employs both training-time suppression and inference-time neuron attenuation to enhance cross-method detection performance.
