OUT OF DATE
ALREADY. Will be updated.
Note: Here are some background information of the area I study.
For my OWN work, please see
Publications.
Semi-Supervised
Learning
I
planed to write something for Semi-supervised Learning.
However, after reading
Zhu Xiaojin's PhD dissertation
(now Assistant Professor at UWisconsin), I find it far better to read
his
thesis. He also maintains a
web
page that puts together the historical and cutting edge research
in semi-supervised learning. The work is up-to-date (May
2005), clear and comprehensive. Proudly, I got my
Bachelor's degree from the same university as Prof. Zhu, Shanghai Jiao Tong University (though he graduated and
left the university 3 years before I was admitted)
.

Learning on Structured Data
I also planed to write something for
Structured Data. However, after reading
Ben Taskar's PhD
dissertation, I find it far better to read his
thesis. It contains his work
that won the Student's Award for NIPS 2003. The work is
up-to-date (December 2004), clear and comprehensive.
Here
is a list (must be incomplete) of recent papers (up to early 2005) on machine
learning with structured data.

Optimization tools and miscellaneous Linux programming skills
There is a huge number of
optimization tools/software available online. What I like to
use is
TAO,
based on
PETSc. This package utilized
MPI, thus it is
very suitable for maximum entropy models and CRF. In fact, we
used 30 processors to compute the objective function value and
gradient (expectations) in parallel, by uniformly distributing data
examples to all processors available and then assemble their
contribution to calculate the gradient.
