New Method of Design Hierarchical Support Vector Machine Multi-class Classifier

Designing the hierarchical structure is a key issue for the hierarchical support vector machine multi-class classification.Inter-class separability is an important basis for designing the hierarchical structure.A new method based on linear support vector machines is proposed to measure inter-class separability.Furthermore,a method is presented which designs a hierarchical support vector machine multi-class classifier based on the inter-class separability.Experimental results indicate that the new method speeds up the hierarchical support vector machine multi-class classifiers and yields higher precision.
