Data mining technique with diversity promotion

摘要: Roughly described, a computer-implemented evolutionary data mining system includes a memory storing a candidate gene database in which each candidate individual has a respective fitness estimate; a gene pool processor which tests individuals from the candidate gene pool on training data and updates the fitness estimate associated with the individuals in dependence upon the tests; and a gene harvesting module for deploying selected individuals from the gene pool, wherein the genepool processor includes a competition module which selects individuals for discarding in dependence upon both their testing experience level and a diversity measure of indi viduals in the gene pool.
