Abstract:

Independent Component Analysis (ICA), a method for separating a mixture of different components into its constituents, has been proposed for a variety of different applications, including functional Magnetic Resonance Imaging (fMRI) of brain processes. The presentation summarizes the findings of several years of interaction between applied mathematicians and neuroscientists, expert in fMRI, concentrating on probing ICA methods for brain fMRI. This study raised questions, informed by mathematical considerations, that are investigated using numerical simulations and specially designed fMRI experiments. The intent was not to cast doubt on the successes of ICA methods for fMRI data analysis, but rather to understand the elements that determine the methods' success; this led us to a surprising result.

Short biography:

Ingrid Daubechies received both her Bachelor's and Ph.D. degrees (in 1975 and 1980) from the Free University in Brussels, Belgium. She held a research position at the Free University until 1987. From 1987 to 1994 she was a member of the technical staff at AT&T Bell Laboratories, during which time she took leaves to spend six months (in 1990) at the University of Michigan, and two years (1991--93) at Rutgers University. She is now at the Mathematics Department and the Program in Applied and Computational Mathematics at Princeton University. Her research interests focus on the mathematical aspects of time-frequency analysis, in particular wavelets, as well as applications.

In 1998 she was elected to be a member of the National Academy of Sciences and a Fellow of the Institute of Electrical and Electronics Engineers. The American Mathematical Society awarded her a Leroy P. Steele prize for exposition in 1994 for her book "Ten Lectures on Wavelets," as well as the 1997 Ruth Lyttle Satter Prize. From 1992 to 1997 she was a fellow of the John D. and Catherine T. MacArthur Foundation. She is a member of the American Academy of Arts and Sciences, the American Mathematical Society, the Mathematical Association of America, the Society for Industrial and Applied Mathematics, and the Institute of Electrical and Electronics Engineers.
