WebSep 19, 2024 · In this article, we adapted five recent SSL methods to the task of audio classification. The first two methods, namely Deep Co-Training (DCT) and Mean Teacher (MT), involve two collaborative neural networks. The three other algorithms, called MixMatch (MM), ReMixMatch (RMM), and FixMatch (FM), are single-model methods that rely … Webdirectly. Besides, mean-teacher employs a consistency regularization to encourage similar predictions from the teacher and the student model. FixMatch [7] assumes that the consistency should also hold between images applied with augmentations of different degrees, and applies both a weak and a strong set of data augmentations.
