Automatic Classification of Ultrasonic Harbor Porpoise Clicks in a Varying Noise Environment

Creator:

De Leon, Daniel

Abstract:

This study compares three approaches in the design of an autonomous machine listening agent that predicts harbor porpoise ultrasonic echolocation clicks in diverse noise environments. Considering the temporal variations of noisy coastal ocean soundscapes which the harbor porpoises inhabit, we propose a leave-one-day-out (LODO) cross-validation strategy in the training of...

Multi-instance multi-label learning : algorithms and applications to bird bioacoustics

Creator:

Briggs, Forrest

Abstract:

We consider the problem of supervised classification of bird species from audio recordings in a real-world acoustic monitoring scenario (i.e. audio data is collected in the field with an omnidirectional microphone, without human supervision). Obtaining better data about bird activity can assist conservation efforts, and improve our understanding of their...
