Standard Triangular Whitenization Weight Function and Its Application in Grey Clustering Evaluation

摘要

In order to deal with the clustering evaluation for overlapping or discontinuous grey class intervals, this paper presents a standardized form of triangular whitenization weight function named standard triangular whitenization weight function by comparing and studying the end-point triangular whitenization weight function and center-point triangular whitenization weight function. With the standardization of triangular whitenization weight function, the left increasing area and right decreasing area of triangular whitenization weight function of the grey class can be unified to one same simple expression. Lastly, the efficiency of standard triangular whitenization weight function is verified through example analysis.
