Webfit (X, y, sample_weight = None) [source] ¶ Build a forest of trees from the training set (X, y). Parameters: X {array-like, sparse matrix} of shape (n_samples, n_features) The training input samples. Internally, its dtype will be converted to dtype=np.float32. If a sparse matrix is provided, it will be converted into a sparse csc_matrix.
