sklearn.preprocessing.binarize¶

sklearn.preprocessing.binarize(X, threshold=0.0, copy=True)[source]¶

Boolean thresholding of array-like or scipy.sparse matrix

Read more in the User Guide.

Parameters

X{array-like, sparse matrix}, 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.

thresholdfloat, 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.

copyboolean, optional, default 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).

Performs binarization using the Transformer API (e.g. as part of a preprocessing sklearn.pipeline.Pipeline).
