Description
PyHa Analyzer is a bird call classification system that I helped develop at UC San Diego as a part of the Engineers for Exploration research cohort of Summer 2023. It uses multiple different convolutional neural networks on audio spectrograms to classify bird calls by species. Project is in collaboration with the San Diego Zoo Wildlife Alliance.
