Weakly Supervised Detection and Temporal Localization of Whale Calls in Long-Duration Bioacoustic Data
Researchers developed DSMIL-LocNet, a weakly supervised machine learning framework that automates both detection and temporal localization of whale calls in long-duration underwater recordings using only recording-level labels rather than frame-by-frame annotations. The system achieves F1 scores of 0.88-0.91 on recordings up to 30 minutes, significantly outperforming fully supervised baselines that degrade to 0.19-0.64 on the same task.
