initializeVectorAttributesForVertex: Initialize numerically-valued vertex attributes

In robertness/signalgraph: Signal Processing with Graphs

Description

For each vertex, there are several sets of vectors representing data and calculations made on the data. These are stored as vertex attributes in the form of numeric objects wrapped in a list so the length is one. The vector attributes are;

• input.signalThe vector of linear combination of values from the parent nodes

• output.signalThe output of the activation function applied to input.signal

• f.prime.inputThe derivative of the activation function applied to the input.signal

• observedObserved values in the data. Not present for hidden and input nodes.

All of these are initialized with NA values

Usage

initializeVectorAttributesForVertex(g, v.index)

Arguments

g	graph model
v.index	vertex index

Value

and igraph object where the above attributes are initialized to the value list(rep(NA, g$n))
