I have come up with a simplistic approach to imagination

based primarily on the way Bill proposes imagination to

occur, i.e., the three levels of interaction of ECS'. Now

this says nothing of how or why imagination is triggered by

that level (n+1) ECS, but it does say what to do when it

happens.

Let's set up a scenario...

OK, the level (n+1) ECS, we'll call ECS top.

Next there are three lower level (n) ECS', which we'll call

ECS M1, ECS M2, and ECS M3, (M=middle).

Lastly ther are also three even lower level ECS', which we'll

call ECS B1, ECS B2, and ECS B3, (B=bottom level).

So the ECS (B1 to B3) are the ones that are short circuited

according to Bill's model, and the ECS' (M1 to M3) are the

ones imagining. (For the moment let's assume that those other

level (n+1) ECS', which did not request imagination to occur

are simply shut off during this process for simplicity's sake.

That's the scenario. Now what happens...

One last point, all weights are continuous value and fully

interconnected between layers and upon initialization have

small random weighted values between {-1,+1}.

Let's start be assuming the the error of ECS top is >0

and error is calculated by the rule E=R-P, where

R=net weighted sum of references

P=net weighted sum of incoming percepts.

ECS top>0 ==> R-P>0 ==> R>P (==> = implies)

the necessary action here is therefore to

increase P and decrease R.

Which is better to do? What are the implications? I'm

not sure at this point. We must remember WHY we are doing

this - it is because we haven't been able to control our

percepts entering into ECS top.

The course of action I'm proposing to alleviate this

mismatch is the following:

To increase Net Percept of ECS top do the following -

1) Consider an arbitrary percept weight, Wn, entering

into ECS top along with thhe percept signal, Pn.

2) If Wn*Pn>0

If Wn>0 and Pn>0

Wn=Wn+Delta

Else

Wn=Wn-Delta

Else

If Wn>0 and Pn<0

Wn=Wn-Delta

Else

Wn=Wn+Delta

3) What's Delta?

Delta is, I feel, something related to a portion

of the error.

I propose the following:

Delta = L*ABS(E)

L= proportion factor, say 0.2

E= error of ECS top.

This same sort of process would be applied to

the outputs of ECS top also.

I think we would have stability in finding the

equilibrium due to the porportion of the error, L,

being less than one.

Any comments?

(Keep in mind this is more or less a little

idea that popped into my head,but I thought

it was worth sharing anyways.)
