  "Description": "Provides a genetic algorithm for finding variable subsets\nin high dimensional data with high prediction performance. The\ngenetic algorithm can use ordinary least squares (OLS)\nregression models or partial least squares (PLS) regression\nmodels to evaluate the prediction power of variable subsets. By\nsupporting different cross-validation schemes, the user can\nfine-tune the tradeoff between speed and quality of the\nsolution.",
