LIBSVM: A Library for Support Vector Machines
LIBSVM: A Library for Support Vector MachinesChih-Chung Chang and Chih-Jen LinDepartment of Computer ScienceNational Taiwan University, Taipei, TaiwanEmail: version: 2001 Last updated: January 20, 2021 AbstractLIBSVM is a Library for Support Vector Machines (SVMs). We have beenactively developing this package since the year 2000. The goal is to help usersto easily apply SVM to their applications. LIBSVM has gained wide popu-larity in machine learning and many other areas. In this article, we presentall implementation details of LIBSVM. Issues such as solving SVM optimiza-tion problems, theoretical convergence, multi-class classification, probabilityestimates, and parameter selection are discussed in :Classification,LIBSVM, optimization, regression, Support Vector ma-chines, SVM1 IntroductionSupport Vector Machines (SVMs) are a popular machine learning method for classifi-cation, regression, and other learning tasks.
