1. An information processor comprising: detecting means for detecting a multiplicity of combinations of n parameter values, where n is a natural number, for each of a plurality of operation modes in which an object functions, which values vary with operation; and Self-Organizing Map creating means for creating a Self-Organizing Map by using detection data, obtained on the basis of the multiple combinations of parameter values detected by said detecting means, as learning data; wherein said Self-Organizing Map creating means creates a plurality of the Self-Organizing Maps, serving as individual separation models and corresponding one to each of the plurality of operation modes.
