Neural Network Theory Research

About


The complexity of our brains, of the multiple tasks they simultaneously perform in multiple ways, of the many circuits they include and the ways these interact, brings upon us a great challenge when we try to explain them.
This is perhaps the greatest scientific challenge of our lifetime. Related questions arise that are interesting as well: "What approaches should we take to study the brain?", "Which areas within the brain should we study?", "What level of details (molecules, neurons, networks or cognitive modules) would be most informative to study?", "Can we learn solely from observation or must we have some models to test?", "Do we have the necessary physical and mathematical tools we need?" are examples of such questions.

I don't think that I have the right definitive answers. I'm not even sure such answers exist. But I have come to the conclusion that discussing these questions is important. Read More

Notes


Notes on Mean-Field Calculation of Random Network Dynamics and their related Lyaponuv Exponents


The notes are the details behind the paper "Chaos in RNN" by Sompolinsky et al. 88'
They are based on Larry Abbott class notes (equations 1-36)
And were extended to include the second half of the paper by myself, with his blessing (equations 37-end)the notes
