We propose a new, robust boosting method by using a zer0-0ne step func- tion as a loss function.In deriving the method, the margin boost technique is blended with the derivative approximation algorithm, called Stochastic Noise Reaction (SNR).Based on intensive numerical experiments, we show that the proposed method is actually better than other boosting methods on test error rates in the case of noisy, mislabeled situation.
