Constructor & Destructor Documentation

Edge::Edge	(	double	startWeight,
		Node *	input = nullptr,
		Neuron *	output = nullptr
	)

Create a new Edge between 2 Nodes. Start with given weight

Parameters

startWeight	initial weight of the edge
input	start node of the edge
output	end node of the edge

Member Function Documentation

double Edge::getWeightedDelta

(

)

Get the delta from the output Neuron weighted for back propagation

Returns

the delta of output node weighted with the current edge weight

double Edge::getWeightedOutput

(

)

Get the output from the edge

Returns

the input weighted with the current edge weight

void Edge::setInput

(

Node *

input

)

Set the Node this Edge starts at

Parameters

input

node to set for input of edge

void Edge::setOutput

(

Neuron *

output

)

Set the Neuron this Edge ends at Note: must be Neuron (not just Node) to allow for retrieving delta for training

Parameters

output

node to set for output of edge, must be a neuron not just a node to allow for retrieving delta for training

void Edge::updateWeight

(

double

learningRate

)

Update the weight for the edge based on the backpropagation algorithm

Parameters

learningRate

distance to update weight
