backward_subset_selection_conditioning
(X, kappa=1000)[source]¶ Conditioning through subselecting columns of X.
Uses svd_subset_selection to greedily remove single columns of X till the desired conditioning is reached.
Parameters: - X : array, shape (n_samples, n_features)
Array whose columns we wish to subset.
- kappa : float, optional, default: 1000
The maximum condition number desired.
Returns: - C : array, shape (n_samples, ?)
Array with condition number < kappa, containing the lesser linearly dependent columns of X.
