What do you do with Data Science?
Steve Zucker's research goal is to understand how the mammalian brain processes visual information. The challenge is to relate the complex responses of thousands of neurons to an ensemble of stimuli; and to then infer which of these neurons are likely involved in functional circuits. His approach involves both tensor factorization, to putatively relate neural responses to the stimuli, and manifold learning techniques, to organize the neurons in a manner that suggests which 'nearby' neurons (on the manifold) could form functional circuits. His work is being done in collaboration with experimental groups at Duke University (retina) and the University of California, San Francisco (cortex).
