Abstract:
In this paper, an adjacent substitution rate estimation method based on weighted Euclid distance is proposed in order to improve the disadvantage of estimating weight by experience. It is based on Support Vector Machine(SVM). The proposed method is applied to the demand forecast of facial cleaning category. Experimental results identify that the predict precision is improved and the objectivity and robustness are both well.
