>> *Title of the talk:  Reverse engineering cortical microcircuit models of
visual perception*

*Abstract*:

Although deep learning has made tremendous strides in visual recognition
and generation, a significant gap remains between human and machine
perception. In this talk, I will argue that models that use stochastic
variables, lateral interactions, and dynamic inference might be required to
close this gap. I will then describe a generative model, Recursive Cortical
Networks (RCN), that partially meets these requirements and demonstrated
excellent performance on some visual task benchmarks.

Using RCN we derive a family of anatomically instantiated and functional
cortical circuit models. Efficient inference and generalization guided the
representational choices in the original computational model. The cortical
circuit model is derived by systematically comparing the computational
requirements of this model with known anatomical constraints. The derived
model suggests precise functional roles for the feed-forward, feedback, and
lateral connections observed in different laminae and columns, assigns a
computational role for the path through the thalamus, predicts the
interactions between blobs and interblobs, and offers an algorithmic
explanation for the innate inter-laminar connectivity between clonal
neurons within a cortical column. The model also explains several visual
phenomena, including the subjective contour effect, and neon-color
spreading effect, with circuit-level precision. Our work paves a new path
forward in understanding the logic of cortical and thalamic circuits.
