Researchers introduce LinguAS, a dataset of 800+ audio samples annotated with linguistic features to improve detection of deepfaked and spoofed speech. Models trained on this linguistically-augmented data significantly outperform existing deepfake detection baselines, addressing a critical gap in audio forensics.
Researchers have developed a method using sparse crosscoders to track how large language models learn linguistic concepts during training, introducing a new metric called Relative Indirect Effects (RelIE) to identify when specific features become causally important. This approach provides interpretable, fine-grained visibility into representation learning throughout pretraining, advancing understanding of how LLMs acquire abstract capabilities.
