To solve the problem that the Multiple Kernel Boosting (MKBoost) algorithm was sensitive to noise

the characteristic that noise data and normal data were treated differently by the optimal classifier was considered

and a MKBoost algorithm applied to datasets polluted by noise data was proposed.The fuse of KNN (K-nearest neighbor) algorithm and logistic regression was used for the construction of noise probability function

and calculating the probability of each instance being noise.A new loss function was constructed via the noise probability function

and addictive model was utilized for computing the coefficients corresponded to base classifier in each iteration.Experiments on the datasets from UCI show that the proposed method could efficiently reduce the sensitivity of MKBoost algorithm to noise

and improved the robustness
