libsvm and liblinear are both software libraries that implement Support Vector Machines. What's the difference? And how do the differences make liblinear faster than libsvm?

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

**LIBSVM**implements the Sequential minimal optimization (SMO) algorithm, for**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.
