Binary feature selection
WebNakamura et al. developed the so-called binary bat algorithm (BBA) for feature selection and image processing [21]. For feature selection, they proposed that the search space is modeled as a -dimensional Boolean lattice in which bats move across the corners and nodes of a hypercube. WebRegression and binary classification produce an array of shape [n_samples]. fit(X, y, **fit_params) [source] ¶ Fit the RFE model and then the underlying estimator on the selected features. Parameters: X{array-like, sparse matrix} of shape (n_samples, n_features) The training input samples. yarray-like of shape (n_samples,) The target values.
