# Machine Learning

I am interested in algorithms and software for machine learning.
In the past we have developed some popular machine learning
packages. An important one is
LIBSVM,
which may be the most widely used
SVM (support vector machines) package.
Another popular package developed in my group is
LIBLINEAR for
large-scale linear classification.
The major computational
task behind machine learning methods
is to solve optimization problems.
I am interested in
large-scale numerical optimization
and its applications.
