| Abstract: | The pretreatment process of twin support vector machine based on Parametric-margin has been improved, principal component analysis to reduce the dimensionality of the data is used in the data preprocessing stage. The twin support vector machines based on principal component analysis speeds up the training process. Experiments on public available datasets show excellent classification ability. Dimensionality reduction of the high-dimensional dataset is also more successful. Finally, this algorithm is applied on handwritten numeral recognition. The experimental results show the effective of our algorithm. |
