Our research groups

GAPS – Grupo de Aplicaciones del Procesado de Señal

GAPS was created in 1988. Today it numbers 8 full-time professors as its members. The group develops research in the general fields of data engineering, system theory and analysis, speech and sound technology, and smart sensor systems, both electromagnetic and ultrasonic. The main focus is on signal theory and data processing. Research areas include distributed processing and deep learning with applications to definition of attack and defense mechanisms in communication networks, autonomous navigation in vehicles.

There is also ongoing work on machine learning as applied to: human-machine interaction, screening and evaluation of clinical conditions based on speech processing, behaviour evaluation and optimisation through reinforcement learning, and algorithmic Trading Systems.

We must add activity on speech analysis, synthesis and recognition, plus artificial audition and spatial sound systems. Finally, a research area develops the theory of non-linear systems using parametric methods and statistical modeling, with applications to precision instrumentation.
