Time-frequency localization of bird calls in dense soundscapes
Simen Hexeberg, Fanghui Tong, Hari Vishnu +1
Passive acoustic monitoring enables large-scale observation of wildlife, but most bioacoustic classifiers only predict species presence in a time window without localizing vocaliza…
Passive Acoustic-based Composite Indices for Reef Health Monitoring in Noisy Tropical waters
Hari Vishnu, Yuen Min Too, Mandar Chitre +3
Passive acoustic monitoring offers the potential to enable long-term, spatially extensive assessments of coral reefs. To explore this approach, we deployed underwater acoustic reco…
Diffusion-based Surrogate Model for Time-varying Underwater Acoustic Channels
Kexin Li, Mandar Chitre
Accurate modeling of time-varying underwater acoustic channels is essential for the design, evaluation, and deployment of reliable underwater communication systems. Conventional ph…
Semi-supervised classification of bird vocalizations
Simen Hexeberg, Mandar Chitre, Matthias Hoffmann-Kuhnt +1
Changes in bird populations can indicate broader changes in ecosystems, making birds one of the most important animal groups to monitor. Combining machine learning and passive acou…
