Who:    Tomaso Poggio, Massachusetts Institute of Technology

Topic:  Models of Visual Recognition in the Ventral Stream: towards a theory


We will describe a class of quantitative models of the ventral stream for
object recognition, which have been developed during the last two decades
from the anatomical and physiological data and which are quite successful in
explaining several physiological data across different visual areas.
Surprisingly, such models also mimic the level of human performance in
difficult rapid image categorization tasks in which human vision is forced
to operate in a feedforward mode. The main focus of the talk will be on
extending these hierarchical models to deal with recognition in image
sequences and to account for computational roles of attention and cortical
backprojections.
Finally we will also sketch initial steps with S. Smale, J. Bouvrie and L.
Rosasco towards a mathematical theory of hierarchical architectures
described by the models of visual cortex.
