Abstract:
Recent technological advances offer unprecedented possibilities for observing and manipulating neural activity. Characterizing the structure of neural circuits is a fundamental problem in brain science, however, unraveling the connectivity and interactions among populations of neurons remains a daunting challenge. In this talk, I address two problems: learning the neural response in retinal ganglion cells, and the estimation of large neuronal networks from calcium imaging data. Utilizing a general computationally scalable framework for estimation of large dynamical structured nonlinear systems, the approach significantly improves over existing methods in both computational cost and performance. This methodology offers provable guarantees in consistency and convergence and is applicable across a wide variety of settings.
