Weakly Supervised Detection and Temporal Localization of Whale Calls in Long-Duration Bioacoustic Data 事件

Weakly Supervised Detection and Temporal Localization of Whale Calls in Long-Duration Bioacoustic Data arXiv:2502.20838v3 Announce Type: replace-cross Abstract: Passive acoustic monitoring (PAM) systems generate continuous recordings spanning months, yet automated bioacoustic analysis of whale calls requires two separate annotation efforts: binary presence labels for classification and precise temporal boundaries for localization. A binary label for a multi-minute recording can be assigned in s
