What's the difference between LibSVM and LibLinear

Question

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?

Answer 1

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.
