Membrane protein plays a crucial role in cells and makes the material basis for cells to implement various functions. In order to predict the type of membrane protein, which is a crucial fundamental research in the field of the structure and function of membrane protein, this paper introduced the position of amino acid and calculated multi-amino acid index correlation coefficients. Then it constructed a new type of membrane protein classification model that combines two feature classes and support vector machine (SVM). Under three typical methods (self-consistency, Jackknife and independent da...
