Pattern recognition system utilizing an expression profile

摘要

When making a clinical diagnosis using gene expression profiles or the like obtained from a DNA microarray, multidimensional data is visualized on a scatter chart so that outliers can be identified and the state of classifications can be recognized. A method comprises calculating said separating hyperplane by applying said pattern recognition algorithm to said training set that is entered; displaying the labels of two axes of said scatter chart in two or three dimensions; applying data of which the group it belongs to is unknown to said pattern recognition algorithm as a test set in order to determine the group the data belongs to; displaying a plot representing the data in said training set and a plot representing the data in said test set on a two- or three-dimensional scatter chart, in different manners for individual groups; and displaying said separating hyperplane by mapping it to said scatter chart.
