Title: Novel approaches to numerical computing using neural algorithms

Abstract

The connection between computation and the brain has been discussed for decades, but specific cases of the fields influencing one another theoretically have been limited.  The need to advance this interaction has increased in recent years, especially with the arrival of brain-inspired “neuromorphic” hardware which promises low-power and rapid simulation of neural models and neural algorithms.  In this talk, I will describe three such intersections.  The first part of the talk will focus on how we can formalize a proposed neural code that accounts for the heterogeneity of neuron connectivity and responses.  This code, which describes neural activity as a combinatorial model, is useful for describing the biological process of adult neurogenesis. The second part of the talk will show how such explicitly constructed neural circuits can then be used to accelerate key numerical kernels efficiently if implemented on neuromorphic hardware. We have developed several examples of this, including correlation and matrix multiplication. Finally, the third part of the talk will describe our approach for neural algorithms for implementing Markov random walk solutions for solving the diffusion equation.
