Abstract  Based on the optimization of the initial basis of the feature space, the Triangle Matrix Feature Transformation method is proposed to calculate the transformation matrix 公式 in feature extraction. In this method, the number of the unknown parameters in the transformation matrix is only half of that in the currently used methods. Thus it reduces the calculation pressure a lot. This method supports various feature transformation criterions, and it is of good flexibility.
