Automatic large-scale classification of bird sounds is strongly improved by unsupervised feature learning

no code implementations26 May 2014 Dan Stowell, Mark D. Plumbley

Feature learning can be performed at large scale and "unsupervised", meaning it requires no manual data labelling, yet it can improve performance on "supervised" tasks such as classification.
