probly.utils.sets¶

Utility functions regarding sets.

Functions

`capacity`(q, a)	Compute the capacity of set q given set a.
`moebius`(q, a)	Compute the Moebius function of a set q given a set a.
`powerset`(iterable)	Generate the power set of a given iterable.

probly.utils.sets.capacity(q, a)[source]¶

Compute the capacity of set q given set a.

Parameters:

q (np.ndarray) – numpy.ndarray, shape (n_instances, n_samples, n_classes)
a (Iterable[int]) – Iterable, shape (n_classes,), indices indicating subset of classes

Returns:

numpy.ndarray, shape (n_instances,), capacity of q given a

Return type:

min_capacity

probly.utils.sets.moebius(q, a)[source]¶

Compute the Moebius function of a set q given a set a.

Parameters:

q (np.ndarray) – numpy.ndarray of shape (num_samples, num_members, num_classes)
a (Iterable[int]) – numpy.ndarray, shape (n_classes,), indices indicating subset of classes

Returns:

numpy.ndarray, shape (n_instances,), moebius value of q given a

Return type:

m_a

probly.utils.sets.powerset(iterable)[source]¶

Generate the power set of a given iterable.
