Research

According to its mission, the Department of Computational Perception carries out basic and applied research in machine learning, pattern recognition, knowledge extraction, and generally Artificial and Computational Intelligence. In terms of application fields, our current focus is on intelligent audio (specifically: music) and image processing.
