connectBindOnState()

The given state of the automaton (see createAutomaton()) turns-off the self.answerObjectCells for all the places, i.e. over all self.numberPlaces.

Below shows the startState of the automaton turning-off the state represented by self.answerObjectCells of just one place. Note that this will be done for all the places in self.numberPlaces.

Note that for the above illustration to be complete two more steps are required

• see stateStopsDone()

createAutomaton(tryToBindStates=10, bindingStates=10, bindDoneStates=6)

Given the arguments tryToBindStates, bindingStates, and bindDoneStates this function creates,

• cell assemblies, and
• three timers (see createTimers())

The cell assemblies are created using FSAHelperFunctions .makeCA. An automaton with five states will therefore have five corresponding cell assemblies as shown below

ooooooooooooo   ooooooooooooo   ooooooooooooo   ooooooooooooo   ooooooooooooo

• the number of cell assemblies for an automaton is determined by self.numberAutomatonStates (default = 15)
• the number of neuron populations within a cell assembly is given by FSAHelperFunctions .CA_SIZE (default = 10)
• the number of neuron units within a population is CA_SIZE * numberAutomatonStates (default = 150)

This function returns the automaton cells, the prototype neuron populations used in constructing the above cell assemblies.

createObjects(numberObjects)

For a given numberObjects this function creates five cell assemblies using FSAHelperFunctions .makeCA

• functionally, one cell assembly each for

  • binding the cells
  • binding the on-cells (“on” state of the cells)
  • binding the done-cells (“done” state of the cells)
  • inquiring about the on-cells
  • answering about the cells

• all cell assemblies

  • have numberObjects times FSAHelperFunctions .halfTurnOnStateFromSpikeSource cells in a population
  • uses the same cell type, IF_cond_exp

Therefore each object is represented by five cell assemblies.

For a population of \(n \times 10\) cells the cell assembly comprises of ten such population.

See createObjects()

createTimers(tryToBindStates=10, bindingStates=10, bindDoneStates=6)

Given the arguments tryToBindStates, bindingStates, and bindDoneStates this function creates three timers,

• self.tryToBindTimer for its given number of states tryToBindStates

  • a timer for accounting the time taken for a binding event

• self.bindingTimer for its given number of states bindingStates

  • a timer for binding

• self.bindDoneTimer for its given number of states bindDoneStates

  • a timer for when the binding is achieved

A timer is a collection of cell assemblies such that

• the number of cell assemblies for a timer correspond to the number of possible states of the timer

• its cell assemblies are connected using TimerClass .makeStopNoRestartTimerSynapses

  • the timer goes from state to state and the last stops on its own
  • if the state that turns it ON remains ON, this timer will not restart until its done

Regardless of the state, i.e. the cell assembly, the

• self.tryToBindTimer.timerCells,
• self.bindingTimer.timerCells, and
• self.bindDoneTimer.timerCells

are its neuron population for the above timers.

statePreventsObjectOutput(stateNumber)

The given state of the automaton (see createAutomaton()) turns-off the self.answerObjectCells for all the places, i.e. over all self.numberPlaces.

Below shows the startState of the automaton turning-off the state represented by self.answerObjectCells of just one place. Note that this will be done for all the places in self.numberPlaces.

stateStopsPlaceDone(stateNumber)

The given state of the automaton (see createAutomaton()) turns-off the self.placeBindDoneCells for all the places, i.e. over all self.numberPlaces.

Below shows the startState of the automaton turning-off the state represented by self.placeBindDoneCells of just one place. Note that this will be done for all the places in self.numberPlaces.
