Constructor Detail

DoubleProxyVertex

public DoubleProxyVertex(VertexLabel label)

This vertex acts as a "Proxy" to allow a BayesNet to be built up before parents are explicitly known (ie for model in model scenarios) but allows linking at a later point in time.

Parameters:

label - The label for this Vertex (all Proxy Vertices must be labelled)

DoubleProxyVertex

public DoubleProxyVertex(long[] shape,
                         VertexLabel label)

DoubleProxyVertex

public DoubleProxyVertex(long[] shape,
                         java.lang.String labelString,
                         DoubleVertex parent)

DoubleProxyVertex

public DoubleProxyVertex(long[] shape,
                         java.lang.String label)

Method Detail

setLabel

public <V extends Vertex<DoubleTensor>> V setLabel(VertexLabel label)

Description copied from class: Vertex

Set a label for this vertex. This allows easy retrieval of this vertex using nothing but a label name.

Overrides:

setLabel in class Vertex<DoubleTensor>

Type Parameters:

V - vertex type

Parameters:

label - The label to apply to this vertex. Uniqueness is only enforced on instantiation of a Bayes Net

Returns:

this

calculate

public DoubleTensor calculate()

Specified by:

setParent

public void setParent(DoubleVertex newParent)

Specified by:

setParent in interface ProxyVertex<DoubleVertex>

getParent
