Detailed Description

A dynamic list of "active" TDConnections (those with a non-zero eligibility trace).

This saves a lot of time by only looping over the active TDConnections, not all of them.

Member Function Documentation

void verve::ActiveTDConnectionList::addNewActiveConnection (  TDConnection *  c  )  [virtual]

Adds a new active TDConnection to the list. If the TDConnection is already in the list, this will do nothing. Definition at line 47 of file ActiveTDConnectionList.cpp. References verve::TDConnection::isInActiveList().

void verve::ActiveTDConnectionList::clearList (   )  [virtual]

Empties the list of active TDConnections and notifies each one that it is no longer in an active TDConnection list. Definition at line 38 of file ActiveTDConnectionList.cpp. References mConnections.

void verve::ActiveTDConnectionList::decayETraces (   )  [virtual]

Decays the eligibility trace of each TDConnection. Definition at line 73 of file ActiveTDConnectionList.cpp. References verve::defaults::activeETraceThreshold, and mConnections. Referenced by verve::RLModule::update().

void verve::ActiveTDConnectionList::increaseETraces (   )  [virtual]

Increases the eligibility trace of each TDConnection, if appropriate. Definition at line 64 of file ActiveTDConnectionList.cpp. References mConnections. Referenced by verve::RLModule::update().

void verve::ActiveTDConnectionList::trainConnections (  real  learningFactorTimesTDError  )  [virtual]

Trains the TDConnections using the given error signal (i.e. learning factor * TD error). Definition at line 107 of file ActiveTDConnectionList.cpp. References mConnections. Referenced by verve::RLModule::trainTDRule().
