Fig. 5.5 Modification of cue probabilities
1. Toggles are pulsed with an Unconditional Clear to reset the output to false. This
nonreversible operation is equivalent to setting the output to false if it was
originally true, and leaving it false if it was false.
2. A Load applies true attributes, when attributes are true, that serve to trigger
multivibration. This is accomplished for each multivibrator in R1. This effec-
tively places all cues into an array of simulated qubits. Note that the Flag qubit
must also be set as a result of a load command.
Modifying Cue Probabilities
For those cues that are true, a modification is desired to lower their probability of
being true. This is equivalent to lowering their frequency of vibration. Lowering
frequency involves increasing delay very slightly, assumed to be possible with
special synapses as suggested in Fig. 5.5 .
It is assumed that delay can be increased slightly with inhibitory-like synapses
that serve to reduce the rate of charging into membrane capacitance. If it takes
longer to charge, signals propagate slower. Increasing delay is equivalent to
switching in a short length of interneuron to increase delay. Increasing delay causes
the frequency of multivibration to decrease and results in a chance that true cues
will be sampled to be false, which is the desired effect.
Note that frequency f x may be reduced smoothly. In this case it is not restricted to
be a harmonic of some lower frequency f 0 .
Upon sampling, which is not shown, cues are thus removed at random to
increase the chance of a match in long-term memory. Each time the simulated
qubits are sampled again, all cues are effectively restored, and different cues are
removed. This system will not add cues or attributes that were not present initially.
