Method Detail

getProbTrue

public Vertex<DoubleTensor> getProbTrue()

logPmf

public double logPmf(BooleanTensor value)

Specified by:

logPmf in class DiscreteVertex<BooleanTensor>

dLogPmf

public java.util.Map<java.lang.Long,DoubleTensor> dLogPmf(BooleanTensor value)

Specified by:

dLogPmf in class DiscreteVertex<BooleanTensor>

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.
