weighted reductions

To apply reductions that are more complicated than summation, the coefficients (or ‘weights’) of the linear combination need to be specified.

observation_reduction

Specifies a sparse weighted sum over observations.

observation_indices : 1d array of integers

Each observation index in the array points to a row of the iid_observations array in the scene object.

weights : 1d array of numbers

Coefficients of the custom linear combination.

edge_reduction

Specifies a sparse weighted sum over edges.

edges : 1d array of integers

Each edge index in the array points to an edge of the branching timeline.

weights : 1d array of numbers

Coefficients of the custom linear combination.

state_reduction

Specifies a sparse weighted sum over multivariate states.

states : 2d array of integers

An array of multivariate states.

weights : 1d array of numbers

Coefficients of the custom linear combination.

transition_reduction

Specifies a sparse weighted sum over state transitions.

row_states : 2d array of integers

An array of multivariate states.

column_states : 2d array of integers

An array of multivariate states.

weights : 1d array of numbers

Coefficients of the custom linear combination.
