**LIBSVM** and **LIBLINEAR** are two popular open source machine learning libraries.** **

**LIBSVM **implements the Sequential minimal optimization (SMO) algorithm, for** **kernelized support vector machines (SVMs), supporting classification and regression.

**LIBLINEAR** implements linear SVMs and logistic regression models

For a large dataset, use liblinear. Libsvm performs very slow at 10k samples.

Hope this answer helps.
