Domestic cat sound classification using transfer learning

Abstract

The domestic cat or house cats (Felis catus) are an ancient human pet animal that can deliver various alert message to human on environmental changes by its mysterious kinds of sounds generation capability. Cat sound classification using deep neural network had scarcity of labeled data, that impelled us to make CatSound dataset across 10 categories of sound. The dataset was even not enough to select data driven approach for end to end learning, so we choose transfer learning for feature extraction. Extracted feature are input to six various classifiers and ensemble techniques applied with predicted probabilities of all classifier results. The ensemble and data augmentation perform better in this research. Finally, various results are evaluated using confusion matrix and receiver operating characteristic curve.
