Claim:
1. A computer-implemented method of evaluating a class of a test datum, the method being implemented in a computing system, said test datum being defined in a data space of dimension D where D≧3, said data space further comprising reference data, the class of each reference datum being known, the method comprising: projecting with an object evaluation computer a set of reference data of the data space into a space of dimension Q where Q<D; calculating with the object evaluation computer a similarity matrix comprising measures of similarities of the test datum with respect to each of the reference data of said set of reference data; defining with the object evaluation computer a region in the projection space for each reference datum, said region being associated with a set of appearance parameters, the appearance parameters associated with the region depending on the measure of similarity between the test datum and the reference datum; evaluating with the object evaluation computer the class of the test datum from the classes of the reference data comprised in one of said regions depending on the appearance parameters associated with said regions; and generating a representation of the regions containing the projections of the reference data with the object evaluation computer on a user interface included in said computing system based on at least some of the appearance parameters, wherein the representation of the regions containing the projections of the reference data with the object evaluation computer on the user interface renders similarities between the test datum and the reference datum to the user, which are visualized on a map.
