Consensus Maximum Margin Criterion for Classification of Proteomic Profile

Article Preview

Abstract:

We propose a new technique for cancer diagnosis from proteomic profile, which mainly contains four steps. Firstly, the original profiles are preprocessed by baseline correction, denoising, compression and rescaling. Then, the profiles are modelled by maximum margin criterion (MMC) analysis. After that, a consensus technique is utilized to identify the discriminant features. Finally, support vector machine (SVM) is applied to classify the modelling data. To study the validity of the proposed method, it is worked on classifying two proteomic profile datasets, the normal and the cancer samples. The results show that the method is efficient.
