Active topics (contact me for collaboration)

Continual Learning for Music
Making deep learning systems more adaptable to real-world music scenarios.

Evaluation of discriminative music embeddings
Hollistic evaluation of music embeddings: robustness, ease of information extraction, and generalizability.

Audio Fingerprinting using self-supervised learning
Learning optimal fingerprints for music identification and broadcast monitoring.

Music rearrangement
Methods for rearranging a music recording so that it matches a new duration.

Audio-based hierarchical structure analysis and similarity |
Methods for computing a hierarchical representation of music structure from recordings and defining a similarity metric between them. Utilized for music similarity metrics and cover song identification.

Computational approaches to music cultural heritage preservation |
Digital music library audio-feature-based organization, indexing, visualization, and searchability.
