Efficient Sequential Minimal Optimisation of Support Vector Classifiers

  • Gavin C. Cawley
Conference paper


This paper describes a simple modification to the sequential minimal optimisation (SMO) training algorithm for support vector machine (SVM) classifiers, reducing training time at the expense of a small increase in memory used proportional to the number of training patterns. Results obtained on real-world pattern recognition tasks indicate that the proposed modification can more than halve the average training time.
