Detailed Description

Motivation

The Pattern object represent a configuration (partial or complete) of the network that can be used by a learning algorithm as model to learn. A LearningAlgorithm will use Pattern for setup network's inputs, spread network and eventually calculate the error, and modify the network's paramenters on the basis of neurons activities in order to get closer to neuron activities presented by the Pattern

Description

Pattern simply associates inputs/outputs pairs to Clusters:

  Pattern pat;
  pat->setInputsOf( anInputCluster, Inputs );
  pat->setOutputsOf( anOutputCluster, Outputs );
  pat->setInputOutputsOf( anHiddenClusterToReset, Inputs, Outputs );
  //--- retrieve stored information:
  pat[aCluster].inputs;
  pat[anotherCluster].outputs;
  //--- add/modify informations:
  pat[aNewCluster].outputs.assign( aRealVecOfData );
  pat[aNewCluster].outputs += 3.0;

Warnings

Pay attention when you use operator[] because it silently add new data. Like std::map::operator[]

Todo:

Supports for storing all properties of Cluster... storing Linkers info ?!?!

Member Function Documentation

void setInputsOf	(	Cluster *	,
		const RealVec &
	)

set the inputs associated with Cluster passed

void setOutputsOf	(	Cluster *	,
		const RealVec &
	)

set the outputs associated with Cluster passed

void setInputsOutputsOf	(	Cluster *	,
		const RealVec &	inputs,
		const RealVec &	outputs
	)

set the both inputs and outputs associated with Cluster passed

const RealVec& inputsOf

(

Cluster *

)

const

return stored information if exists, otherwise it return a zero vector

const RealVec& outputsOf

(

Cluster *

)

const

return stored information if exists, otherwise it return a zero vector

PatternInfo& operator[]

(

Cluster *

)

return the stored information

Warning:

it silently create a new one if the Cluster passed is not present
