Abstract: In ordinary Support Vector Machine，for each elment（x_i，y_i），i=1，2，…，l of a training set，input of x_i has a definite class number y_i.While in practice，class of x_i is rarely fixed，x_i generally belongs to positive Class with probability of z_i⁺ or xi generally belongs to negative class with probability of z_i^-.In that light，this paper has modified the training set，In which yi is replaced by z_i⁺，z_i^- and classification optimal model and Uncertain Proximal Support Vector Machine are construct in turn.

Key words: uncertain, proximal, Support Vector Machine
