Detailed Description

Abstraction of a connection between two neurons.

A connection has a source, destination and a weight. The source's output is taken as input by the destination

---

Constructor & Destructor Documentation

Link (  Neuron *  to, Neuron *  from )

Creates a link between two neurons. Weight assigned is a random value between -1 and +1 Parameters: to  The destination neuron from  The source neuron

Link (  Neuron *  to, Neuron *  from, real  weight )

Creates a link between two neurons. Parameters: to  The destination neuron from  The source neuron weight  The weight of the connection

virtual ~Link (   )  [virtual]

Destroys the link. When doing so, removes the link from the _outputLinks of the source neuron and the _inputLinks of the destination neuron

Member Function Documentation

Neuron* getDestination (   )  const

Pointer to the destination neuron.

real getLastDeltaWeight (   )

Get the current delta. If updateWeight was called, this will be zero. Otherwise the result will be last value set by setDeltaWeight

Neuron* getSource (   )  const

Pointer to the source neuron.

real getWeight (   )  const

Returns the weight of the link.

bool isEqualTo (  Link *  l  )

Finds if two links are equivalent. Two links are considered equivalent if they are between the same two neurons, irrespective of the weight Returns: true if equivalent, false if not

void setDeltaWeight (  real  delta  )

Sets the change in weight of the link The actual change is made only when updateWeight is called. See also: updateWeight

void setWeight (  real  weight  )

Sets the weight of the link.

void updateWeight (   )

Updates the weight of the link. New weight = old weight + value set by setDeltaWeight Then it resets the change in weight so successive calls to updateWeight have no adverse effect. See also: setDeltaWeight
