sklearn.utils.sparsefuncs. inplace_csr_column_scale(X, scale)[source]¶
Inplace column scaling of a CSR matrix.
Scale each feature of the data matrix by multiplying with specific scale provided by the caller assuming a (n_samples, n_features) shape.
| Parameters: | X : CSR matrix with shape (n_samples, n_features) Matrix to normalize using the variance of the features. scale : float array with shape (n_features,) Array of precomputed feature-wise values to use for scaling. |
