This paper presents the results of a study demonstrating that applying Consistency Regularization (CR) to audio event recognition improves performance on the AudioSet dataset. Applying CR to a robust supervised learning-based model that leverages data augmentation demonstrates significant performance improvements, particularly on a small training dataset (approximately 20,000 data points). Furthermore, applying CR to a robust augmentation technique and multiple augmentation techniques yields additional performance improvements on small training datasets. Furthermore, applying CR to a semi-supervised learning setup with 20,000 labeled and 1.8 million unlabeled samples also achieves performance improvements.
