Twin Support Vector Machine for Clustering
Zhen Wang, Yuan‐Hai Shao, Lan Bai, Nai-Yang Deng · IEEE Transactions on Neural Networks and Learning Systems · 2015
The twin support vector machine (TWSVM) is one of the powerful classification methods. In this brief, a TWSVM-type clustering method, called twin support vector clustering (TWSVC), is proposed. Our TWSVC includes both linear and nonlinear versions. It determines k cluster center planes by solving a series of quadratic programming problems. To make TWSVC more efficient and stable, an initialization algorithm based on the nearest neighbor graph is also suggested. The experimental results on several benchmark data sets have shown a comparable performance of our TWSVC.
