System and method for identifying an object

A system for determining the classification of a signal comprising:

• a plurality of training signals associated with one or more known classifications, wherein each of the training signals has a plurality of training signal attributes;
• a first reduct calculator for calculating one or more reducts that include the minimum number of training signal attributes that are required to correctly classify the plurality training signals;
• a classifier for classifying a plurality of unclassified signals as a function of the one or more reducts and one or more attributes of the unclassified signals;
• a marginal reduct identifier for determining if one or more reducts provided one or more marginal classifications;
• and
• a reduct classification fuser for combining one or more marginal reducts identified by the marginal reduct identifier.

A method of determining to what classification a signal belongs, the method comprising the steps of:

• providing a classification system including a subset of training signals and a plurality of reducts, the classification system having been determined by the steps of:
• providing a training information set in the form of a table of data, the table having a plurality of columns and rows, wherein each column of the table represents an attribute of the classification and wherein each row of the table is a training signal and represents attributes associated with a specific classification;
• partitioning the training signals;
• wavelet transforming signals in each of the training signal partitions and appending wavelet coefficients as additional signal values;
• labeling signals resulting from the wavelet transforming step;
• selecting a subset of the plurality of columns by removing duplicate and ambiguous signals;
• calculating the plurality of reducts;
• providing a set of test signals in the form of a table with a plurality of columns of attributes and rows of test signals;
• determining a classification of each test signal of the plurality of test signals using the classification system.
