Heuristic method of classification
First Claim
1. A method of creating a classifying pattern for objects using a plurality of data strings, each data string associated with one of a plurality of objects to be classified, comprising:
- selecting a set of data elements from each data string using a learning algorithm;
classifying the set of data elements using a pattern recognition algorithm; and
repeating the selecting and classifying with a different set of data elements selected from each data string until a classifying pattern is created that is acceptable to classify the objects.

Abstract
The invention concerns heuristic algorithms for the classification of Objects. A first learning algorithm comprises a genetic algorithm that is used to abstract a data stream associated with each Object and a pattern recognition algorithm that is used to classify the Objects and measure the fitness of the chromosomes of the genetic algorithm. The learning algorithm is applied to a training data set. The learning algorithm generates a classifying algorithm, which is used to classify or categorize unknown Objects. The invention is useful in the areas of classifying texts and medical samples, predicting the behavior of one financial market based on price changes in others and in monitoring the state of complex process facilities to detect impending failures.
