A Combination of Hand-Crafted and Hierarchical High-Level Learnt Feature Extraction for Music Genre Classification

摘要

In this paper, we propose a new approach for automatic music genre classification which relies on learning a feature hierarchy with a deep learning architecture over hand-crafted feature extracted from an audio signal. Unlike the state-of-the-art approaches, our scheme uses an unsupervised learning algorithm based on Deep Belief Networks (DBN) learnt on block-wise MFCC (that we treat as 2D images), followed by a supervised learning algorithm for fine-tuning the extracted features. Experiments performed on the GTZAN dataset show that the proposed scheme clearly outperforms the state-of-the-art approaches.
