Progress on the CBMM challenge questions: What/Who is there?

Abstract:
In the Jeopardy/Watson effort every week on Friday there was an evaluation of performance. We continue the series of weekly discussions and reports on each CBMM challenge question [e.g. What is there? What will happen next? What are they doing? etc.] describing progress and problems of ongoing work at CBMM.

The Allen Institute for Brain Science uses a big science approach to neuroscience, integrating experiment, modeling and theory. One of the Institute’s projects, MindScope, is an exploration of the mouse visual system from a multitude of coordinated approaches. I will give an overview of the MindScope project and the “C3” approach – Components, Computation, and Cognition, and discuss how the goals of MindScope relate to the goals of CBMM. Important goals along our Cognition axis are Object Recognition, Attention, and Decision Making in the mouse cortico-thalamic system. The M-Theory framework provides a feedforward architecture which computes invariant representations of the visual field, facilitating fast object recognition which mimics human performance on recognition tasks within about 100ms. Several results suggest that recognition beyond 100ms or so involves feedback. I will discuss some preliminary ideas on extending the M-Theory framework to include feedback, in particular by incorporating elements of probabilistic inference into the model.
