Abstract:
1. A method of constructing a vector space in which a data sample relating to an object may be encoded, comprising: providing a raw matching score between each of a plurality of basis sample elements and each of a plurality of data samples in a first sample database using a score generator, the data samples in the first sample database being out-of-sample with respect to the basis sample elements; constructing a sample space from the raw matching scores using a sample space construction module implemented on a computer, the sample space being defined by a basis set of sample space modes and structured such that a similarity between a data sample relating to an object encoded in the sample space and one or more of the data samples in the first sample database can be identified by determining a matching score between the data sample relating to the object and one or more of the plurality of basis sample elements.
