Transductive inference based on support vector machine is a relatively new research region in statistical learning theo- ry.Compared with traditional inductive learning,tranaductive inference is often more practical and can give results with better perform- ance.In allusion to the shortcoming of progressive tranaductive support vector machine learning algorithm,an improved algorithm is pres- ented in this paper.Using region labeling rule to substitute the former's twin label rule,this algorithm inherits the...
