I am, in general, interested in understanding how intelligent behavior (broadly defined) emerges from brain-like computational architectures. I use ideas and tools from deep learning and computational neuroscience to address this question.

Here are some notes I have written over the years:

Cover's function counting theorem | Dirichlet processes | Helmholtz machine | Hopfield model | leaky integrate-and-fire neuron | linear dynamics in Schur modes | locally linear embedding | Isomap algorithm | particle filtering.

Please send me an e-mail if you find any typos, errors, inaccuracies or grave omissions in these notes.
