  "Description": "A variable selection procedure, dubbed KKO, for\nnonparametric additive model with finite-sample false discovery\nrate control guarantee. The method integrates three key\ncomponents: knockoffs, subsampling for stability, and random\nfeature mapping for nonparametric function approximation.
