Constructor Detail

CPTVertex

public CPTVertex(java.util.List<Vertex<? extends Tensor<java.lang.Boolean>>> inputs,
                 java.util.Map<CPTVertex.Condition,Vertex<OUT>> conditions,
                 Vertex<OUT> defaultResult)

Method Detail

sample

public OUT sample(KeanuRandom random)

Specified by:

sample in class Vertex<OUT extends Tensor>

Parameters:

random - source of randomness

Returns:

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

getDerivedValue

public OUT getDerivedValue()

Specified by:

getDerivedValue in class NonProbabilistic<OUT extends Tensor>
