pasteur.graph.loss.ParentMeta

class pasteur.graph.loss.ParentMeta(sum_dims: tuple[int, ...], idx: ndarray | None = None, b_doms: tuple[int, ...] = (), transpose: tuple[int, ...] = (), transpose_undo: tuple[int, ...] = ())

Contains the necessary metadata to align a parent clique to an observation clique.

First, attributes that are not present in an observation clique are summed out. Then the common dimensions that are different are transposed to the front and indexed. Finally, the transpose is undone and the cliques are aligned.

Attributes

b_doms	Alias for field number 2
idx	Alias for field number 1
sum_dims	Alias for field number 0
transpose	Alias for field number 3
transpose_undo	Alias for field number 4

Methods

count(value, /)	Return number of occurrences of value.
index(value[, start, stop])	Return first index of value.

b_doms: tuple[int, ...]

Alias for field number 2

count(value, /)

Return number of occurrences of value.

idx: ndarray | None

Alias for field number 1

index(value, start=0, stop=9223372036854775807, /)

Return first index of value.

Raises ValueError if the value is not present.

sum_dims: tuple[int, ...]

Alias for field number 0

transpose: tuple[int, ...]

Alias for field number 3

transpose_undo: tuple[int, ...]

Alias for field number 4
