Since Fall 2016, I am working with
Csaba
in Statistical Machine Learning.
I am finding
bandit algorithms
quite interesting.
And there is online learning and reinforcement learning.
It seems that optimization is one pervasive theme in machine learning,
though it comes up in a variety of flavours and colours that it isn't boring.
Plus just optimization doesn't quite do it... to really be talking about learning
one has to pay attention to generalization.
This winter term I am doing some deep learning.

I spent some time with
Mauricio's
group looking at some signal analysis related things.
Before that I was working with
Sasha and
Nicole
using some geometric functional analysis and probability
for estimating the smallest singular value of a sparse random matrix.
Even before that I worked with
Byron
on reversibility of a Brownian motion with drift.
As an undergrad, I had fun with a project with
Loretta
about repeated games with incomplete information.
