1. A system for identifying an object wherein said object is represented by a signal, comprising:
- a computer system;
a training information data set, said training set in the form of a table having a plurality of rows and a plurality of columns, wherein each row represents a signal and each column represents attributes associated with each given signal;
a labeler;
a reduct calculator;
a testing information data set; and
a reduct classification fuser.

Abstract
A system and method for determining the classification of a signal, or the identification of an object is provided. Based on rough set theory, or data mining, a training data set (105) is partitioned (105) and labeled (125) with a multi-class entropy method. Reducts (145) are calculated from a sub-set of the best-performing columns (130) of the partitioned and labeled training set data. These reducts are applied to test signals and combined for each signal classification. The present system and method produces a more accurate, robust and efficient classification result.

20. A data-mining method of determining what classification a signal belongs to, the method comprising 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 signal and represents all the attributes associated with a specific classification;
binary labeling the signals;
selecting a subset of the plurality of columns, each column in the subset having a higher information index than any of the remaining columns in the plurality of columns that were not selected;
calculating each of the 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 separate reduct classification of each of a plurality of test signals using each of the reducts; and
determining a final classification of each test signal of the plurality of test signals by combining each of the separate reduct classifications for each of the test signals. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
