RIKEN Center for Advanced Intelligence Project Functional Analytic Learning Unit

Unit Leader: Minh Ha Quang (Ph.D.)

Research Summary

Minh  Ha Quang(Ph.D.)

The Functional Analytic Learning Unit focuses on theories and methods from functional analysis and related fields in machine learning, in particular methods based on reproducing kernel Hilbert spaces (RKHS), matrix and operator theory, Riemannian geometry, information geometry, and optimal transport. An important direction is the theoretical formulations and algorithms based on infinite-dimensional geometrical methods, especially in the RKHS setting. The targeted application domains include, but are not limited to, functional data analysis, computer vision, image and signal processing, brain imaging, and brain computer interfaces.
