tfl.test_utils.get_linear_lattice_interpolation_fn

Returns function which does lattice interpolation.

tfl.test_utils.get_linear_lattice_interpolation_fn(
    lattice_sizes, monotonicities, output_min, output_max
)

Returned function matches lattice_layer.LinearInitializer with corresponding parameters.

lattice_sizes list or tuple of integers which represents lattice sizes.
monotonicities monotonicity constraints.
output_min minimum output of linear function.
output_max maximum output of linear function.

Function which takes d-dimension point and performs lattice interpolation assuming lattice weights are such that lattice represents linear function with given output_min and output_max. All monotonic dimesions of this linear function cotribute with same weight despite of numer of vertices per dimension. All non monotonic dimensions have weight 0.0.
