Feature selection based on some homogeneity coefficient
The homogeneity coefficient Phi /sup *//sub k/, described is an L/sub 1/-type criterion that can be used in measuring the degree of linear dependence among some measurements. Properties of the criterion Phi /sup *//sub k/ are analyzed. A feature selection procedure based on the coefficient Phi /sup *//sub k/ is described. Maps based on both the perception-criterion function and the homogeneity coefficients are used in the interactive computer system of diagnosis support, Hepar. This system is presently implemented on IBM PC and is to be used in the Clinic Gastroenterology in Warsaw.<>
