Constructor Summary

ExcitationTask(int ticksPerRun, PamNode n, double excitation, PerceptualAssociativeMemory pam)
Instantiates a new excitation task to excite supplied PamNode specified amount.

Method Summary

protected void

runThisFrameworkTask() This method first excites the PamNode, if this puts the PamNode over the percept threshold it creates an AddNodeToPerceptTask to add it to the percept.

Constructor Detail

ExcitationTask

public ExcitationTask(int ticksPerRun,
                      PamNode n,
                      double excitation,
                      PerceptualAssociativeMemory pam)

Instantiates a new excitation task to excite supplied PamNode specified amount.

Parameters:

ticksPerRun - the ticks per run

n - to be excited

excitation - amount to excite

pam - PerceptualAssociativeMemory module

Method Detail

runThisFrameworkTask

protected void runThisFrameworkTask()

This method first excites the PamNode, if this puts the PamNode over the percept threshold it creates an AddNodeToPerceptTask to add it to the percept. In either case it calls PerceptualAssociativeMemory.propagateActivationToParents(PamNode) to pass the node's activation, then the tasks finishes.
