Method Detail

sample

public BooleanTensor sample(KeanuRandom random)

Specified by:

sample in class Vertex<BooleanTensor>

Parameters:

random - source of randomness

Returns:

a sample from the vertex's distribution. For non-probabilistic vertices, this will always be the same value.

calculate

public BooleanTensor calculate()

Specified by:

calculate in interface NonProbabilistic<BooleanTensor>
