From feature engineering to end-to-end learning

Humans classify or annotate music based on diverse characteristics extracted from the audio signals. For example, a heavily distorted electric guitar sound with growling vocals is a good indication of metal music. Swing rhythms, syncopation, and chromatic comping by polyphonic instruments (e.g., piano or guitars) are obvious cues that the music is jazz. Translating these acoustic and musical features into numerical representations that computers can interpret is the essence of music classification and tagging. This usually involves a series of computation steps that convert audio content into a time–frequency representation, extract discriminative features, summarize them over time, and repeat the feature extraction and summarization until the proper category for the music can be determined. The way of improving each feature extraction step to achieve the best performance has evolved with advances in learning algorithms from hand engineering based on domain knowledge to end-to-end learning. Humphrey et al. [9] explained the transition in a unified deep architecture model where multiple blocks of affine transformation, nonlinear function, and optional pooling operation are pipelined. Figure 1 illustrates four different feature representation approaches in their framework. In reviewing the evolution of such approaches, we first separate them into two classes: feature engineering and feature learning.
