We meet WEDNESDAYS 11:10 - noon in Room 380 Soda Hall, Berkeley campus.
The coordinators are Profs. J. Demmel (demmel at cs.berkeley.edu), 
M. Gu (mgu at math.berkeley.edu), and B. N. Parlett (parlett at math.berkeley.edu). 
The program will be a mixture of research talks and tutorials.
The tutorials will provide a partial sequel to Math 221.

         Mathematics, Russian Academy of Sciences
Title: Tensor approximation tools free of the curse of
       dimensionality
Abstract: Even "simple" case in higher dimensions may require data elements
as many as atoms in the universe. Structure in data in such case
is the key issue. However, existing tenosr reprentations suffer from
various drawbacks. We propose new tensor decompositions called
TENSOR-TRAIN DECOMPOSITIONS and the corresponding numerical algorithms
with then complexity linear in the number of axes. Applications include
interpolation of multi-variate functions, computation of multi-dimensional
integrals, solving PDEs, fast inversion of tensor structured matrices etc.

There will be no seminar on Nov. 11, which is a University holiday.
