skactiveml.utils.check_bound

skactiveml.utils.check_bound(bound=None, X=None, ndim=2, epsilon=0, bound_must_be_given=False)

Validates bound and returns the bound of X if bound is None. bound or X must not be None.

Parameters

bound: array-like of shape (2, ndim), default=None

The given bound of shape [[x1_min, x2_min, …, xndim_min], [x1_max, x2_max, …, xndim_max]]

X: matrix-like of shape (n_samples, ndim), default=None

X is the feature matrix representing samples.

ndim: int, default=2

The number of dimensions.

epsilon: float, default=0

The minimal distance between the returned bound and the values of X, if bound is not specified.

bound_must_be_given: bool, default=False

Whether it is allowed for the bound to be None and to be inferred by X.

Returns

boundarray-like of shape (2, ndim), default=None

The given bound or bound of X.
