An Improved SVM Multiclass Classification Algorithm Based on DAG
Xiaofeng Wang · Journal of Chongqing Jiaotong University · 2009
Aiming at the problem that the SVM multiclass classification algorithm based on DAG doesn't use an effective constructing algorithm of directed acyclic graph,an improved SVM multiclass classification algorithm based on DAG is put forward.The class distance of clustering is taken as the basis of hierarchical classification.The experiment results show that the new method has higher classification accuracy than the original algorithm does.
