摘要

PROBLEM TO BE SOLVED: To appropriately visually detect predetermined data such as an outlier in given arbitrary multidimensional data.;SOLUTION: An outlier visualization apparatus A is used to visualize predetermined data in a plurality of data y forming object data Y by means of a mixed autoregressive model mixing a K number of autoregressive models. In the outlier visualization apparatus A, a model parameter estimation part 11 reads the object data Y into memory, and pairs the data y with input vectors x created from the data y to create a plurality of data D into memory, then an extended probability vector estimation part 12 estimates joint probabilities of the stored data D and classes k into memory, and combines a mean 2 sigma value to the probability vectors to create extended probability vectors into memory, and an outlier visualization part 13 uses the extended probability vectors to visually display the predetermined data.;COPYRIGHT: (C)2005,JPO&NCIPI
