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

annie::Link::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

annie::Link::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 annie::Link::~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* annie::Link::getDestination (    )

Pointer to the destination neuron.

real annie::Link::getLastDeltaWeight (    )

Neuron* annie::Link::getSource (    )

Pointer to the source neuron.

real annie::Link::getWeight (    )

Returns the weight of the link.

bool annie::Link::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 annie::Link::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 annie::Link::setWeight (  real    weight )

Sets the weight of the link.

void annie::Link::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

---

Member Data Documentation

real annie::Link::_deltaWeight [private]

The change in weight to be made. Set this using setDeltaWeight() and then when you've set all weight changes then update the links using updateWeight() See also: setDeltaWeight , updateWeight

Neuron* annie::Link::_from [private]

The source neuron.

real annie::Link::_lastDeltaWeight [private]

Neuron* annie::Link::_to [private]

The destination neuron.

real annie::Link::_weight [private]

The weight of the connection.
