CoveredBy

class hybrid_learning.fuzzy_logic.predicates.custom_ops.CoveredBy(*in_keys, logical_and=None, logical_or=None, mask_dims=(- 2, - 1), keep_dims=False, **kwargs)[source]

Bases: AbstractFuzzyIntersect

Calculate the proportion of one mask covered by another. The value calculates for masks \(A, B\) and fuzzy set membership function \(\in\) as:

\[\min(1, \frac{\sum_c c\in A \wedge c\in B}{\sum_a a \in A})\]

This is the summed fuzzy set intersection over the summed mask \(A\).
