摘要

PROBLEM TO BE SOLVED: To improve accuracy of binary prediction in observation data showing a multidimensional relationship.SOLUTION: Observation data D1 showing a multidimensional relationship and class hierarchical structure taxonomy D2 to be background knowledge for each dimension are input into the observation data expansion unit 2 of a multidimensional data predictor 1. The observation data is expanded by giving class knowledge to an object observed sparse in each dimension. A deficit value prediction unit 3 performs binary prediction for unobserved data by simultaneously analyzing the observation data D1 prior to expansion by the observation data expansion unit and expanded visit candidate data D2 to output visit candidate data D3.SELECTED DRAWING: Figure 1
