Ph.D. Interests

Computational methods of information geometry with real-time applications in audio signal processing

Information geometry is a recent field of mathematics that studies the theory of statistics, by using concepts of differential geometry such as smooth manifolds, and of information theory such as statistical divergences. I am studying the theoretical concepts of information geometry that are useful in the development of computational methods for real-time applications in audio signal processing.
