Constructor Detail

DoubleBinaryOpVertex

public DoubleBinaryOpVertex(int[] shape,
                            DoubleVertex left,
                            DoubleVertex right)

A vertex that performs a user defined operation on two vertices

Parameters:

shape - the shape of the resulting vertex

left - a vertex

right - a vertex

Method Detail

sample

public DoubleTensor sample(KeanuRandom random)

Specified by:

sample in class Vertex<DoubleTensor>

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 DoubleTensor getDerivedValue()

Specified by:

getDerivedValue in class NonProbabilisticDouble

op

protected abstract DoubleTensor op(DoubleTensor left,
                                   DoubleTensor right)

getLeft

public DoubleVertex getLeft()

getRight

public DoubleVertex getRight()
