sklearn.preprocessing.binarize(X, threshold=0.0, copy=True)

Boolean thresholding of array-like or scipy.sparse matrix


X : array or scipy.sparse matrix with shape [n_samples, n_features]

The data to binarize, element by element. scipy.sparse matrices should be in CSR or CSC format to avoid an un-necessary copy.

threshold : float, optional (0.0 by default)

Feature values below or equal to this are replaced by 0, above it by 1. Threshold may not be less than 0 for operations on sparse matrices.

copy : boolean, optional, default is True

set to False to perform inplace binarization and avoid a copy (if the input is already a numpy array or a scipy.sparse CSR / CSC matrix and if axis is 1).
