CA 2411906

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.

La présente invention concerne des algorithmes heuristiques utilisés pour classifier des Objets. Un premier algorithme d'apprentissage comprend un algorithme génétique qui sert à soumettre à un processus d'abstraction un flux de données associé à chaque Objet et un algorithme de reconnaissance de formes qui sert à classifier les Objets et à mesurer la cote des chromosomes de l'algorithme génétique. L'algorithme d'apprentissage génère un algorithme de classification qui sert à classifier ou à catégoriser des Objets inconnus. Cette invention est utile dans les domaines de la classification de textes et de prélèvements médicaux, de la prédiction du comportement d'un marché financier à partir des fluctuations des prix sur d'autres marchés financiers et de la surveillance de l'état de mécanismes de traitement complexes pour détecter des défaillances imminentes.
