Large-scale attribute selection using wrappers
... the test data is only used to evaluate the “best” m best subsets of a particular size. To determine the “optimal” subset size, we average the m scores on the test data for each subset size, and choose the size with the highest average. Then, a final forward selection is performed on the complete dat ...

Genetic algorithm
In the field of artificial intelligence, a genetic algorithm (GA) is a search heuristic that mimics the process of natural selection. This heuristic (also sometimes called a metaheuristic) is routinely used to generate useful solutions to optimization and search problems. Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems using techniques inspired by natural evolution, such as inheritance, mutation, selection, and crossover.
