Detailed Description

A synaptic connection between two Neurons.

Definition at line 34 of file Connection.h.

Constructor & Destructor Documentation

verve::Connection::Connection (  Neuron *  preNeuron, Neuron *  postNeuron )

The pre-synaptic and post-synaptic Neuron pointers here must be non-NULL. Definition at line 29 of file Connection.cpp. References mPostNeuron, mPreNeuron, and mWeight.

verve::Connection::~Connection (   )  [virtual]

Deallocates any dynamically allocated memory. This object should never be destroyed by the user calling 'delete' because memory allocated within the DLL should also be destroyed within the DLL. Definition at line 42 of file Connection.cpp.

Member Function Documentation

void verve::Connection::addToWeight (  real  delta  )  [virtual]

Adds a value to the weight. Automatically updates the input sums of all post-synaptic Neurons. Definition at line 76 of file Connection.cpp. References verve::Neuron::addToSynapticInputSum(), verve::Neuron::getFiringRate(), mPostNeuron, mPreNeuron, and mWeight. Referenced by verve::TDConnection::applyTDLearning().

Neuron * verve::Connection::getPostNeuron (   )  const [virtual]

Returns the post-synaptic Neuron. Definition at line 101 of file Connection.cpp. References mPostNeuron.

Neuron * verve::Connection::getPreNeuron (   )  const [virtual]

Returns the pre-synaptic Neuron. Definition at line 96 of file Connection.cpp. References mPreNeuron.

real verve::Connection::getWeight (   )  const [virtual]

Returns the weight. Definition at line 50 of file Connection.cpp. References mWeight.

void verve::Connection::resetShortTermMemory (   )  [virtual]

Resets temporary dynamics without affecting learned parameters. Reimplemented in verve::TDConnection. Definition at line 46 of file Connection.cpp. Referenced by verve::TDConnection::resetShortTermMemory().

void verve::Connection::setWeight (  real  value  )  [virtual]

Sets the weight. Automatically updates the input sums of all post-synaptic Neurons. Definition at line 55 of file Connection.cpp. References verve::Neuron::addToSynapticInputSum(), verve::Neuron::getFiringRate(), mPostNeuron, mPreNeuron, and mWeight. Referenced by verve::Projection::setInitialConnectionWeight().
