skada.CORALAdapter

skada.CORALAdapter(reg='auto', assume_centered=False)[source]

Estimator based on Correlation Alignment [1]_.

See [5] for details.

Parameters:
reg'auto' or float, default="auto"

The regularization parameter of the covariance estimator. Possible values:

  • None: no shrinkage).

  • 'auto': automatic shrinkage using the Ledoit-Wolf lemma.

  • float between 0 and 1: fixed shrinkage parameter.

assume_centered: bool, default=False

If True, data are not centered before computation.

Attributes:
mean_source_: array, shape (n_features,)
mean_target_: array, shape (n_features,)
cov_source_inv_sqrt_: array, shape (n_features, n_features)

Inverse of the square root of covariance of the source data with regularization.

cov_target_sqrt_: array, shape (n_features, n_features)

Square root of covariance of the target data with regularization.
