The goal is to classify different birds species based on their songs/calls. Spectrograms have been extracted from the audio samples and used as features for classification. A Siamese network based on 1D dilated convolutions is used here. Model is trained using triplet loss. I am using the British Birdsong Dataset available on Kaggle for this experiment.
Download the data from here. This dataset is a subset of Xeno-Canto database. Siamese Networks along with dilated 1D convolutions are used here to classify 9 different bird species.
