JavaScript AI Mind Programming Journal -- 2011 May 13

When the question "who are you" is input repeatedly
to the JavaScript Artificial Intelligence (JSAI), the AI
needs to retain the self-concept of "I" as the subject
for each of all possible answers to the question. The
MindForth AI already performs well in this regard, but
the JSAI has been letting go of the self-concept subject.
Therefore we will try to make sure that the JSAI uses
the same activational routines as MindForth does.
Sat.14.MAY.2011 -- Using Differential PsiDecay
The artificial Mind has difficulty holding onto the subject
of a query because of stray activations that build up on
"also-ran" concepts that were proposed but not accepted
as answers to recent queries. The activation on otherwise
legitimate answers builds up so rapidly and so substantially
that an also-ran concept threatens to dislodge the very
subject of the query and become a new subject of a
thought which does not supply the knowledge requested
by the query. For instance, when we twice ask "who are you"
of the 12may11A.html JSAI as released onto the Web
two days ago, it answers first "I AM ROBOTS" and then
"A PERSON IS PERSON", apparently because the
also-ran concept of "PERSON" has risen too high in
activation to let the self-concept "I" serve as the
subject of the response. Meanwhile, yesterday we
may have had a "eureka" moment that could supply
a solution so simple and yet so effective that it provides
a tipping point in the break-out phenomenon of True AI.
Now, we don't want our AI Minds to start asking
teenage boys if they would like a little game of
GLOBAL THERMONUCLEAR WAR, Matthew,
but don't be surprised if suddenly No Such Agency
starts removing every trace of Mentifex AI from
every corner of the World Wide Web. Did you
know that, when things got a little hot during
World War Two, the U.S. government began
removing books on the mathematics of
Georg Riemann from libraries all over America?
Say, when's the last time you saw a copy of AI4U?
The secret to True AI is to imbue the artificial Mind
not with the linear PsiDecay that MindForth has
always had, but with the differential PsiDecay of
also-ran concepts so that stray activations dwindle
more rapidly from high spikes than from merely
modest spikes. In a living neural-net like the
human brain, do we not expect a sharp spike
to fall more rapidly than a simple upswell?
So let us modify the PsiDecay code and try to
make higher activations subside more rapidly.
We are trying to introduce "differential" psi-decay.
Suppose we have also-ran NounPhrase concepts
like
39=ROBOT at 54 act;
104=PERSON at 68 act;
33=ANDRU at 82 act;
We want the high-activation also-rans to drop to
an activation low enough to avoid dislodging the
input subject. Then we want at least one also-ran
to be high enough to be selected as an answer
to the input query. We want each decade or octet
of high activation to be lowered by not just one point,
but by a precipitous drop that still keeps the relative
ranking of the also-rans. For instance, we could
ordain that all activations above thirty could arrange
themselves in a spread between twenty-nine and forty,
so that
39 becomes 31;
49 becomes 32;
59 becomes 33;
69 becomes 34;
79 becomes 35;
89 becomes 36;
99 becomes 37; and so on
Upshot: We inserted similar code into the JavaScript
AI Mind and it began to function better than ever.
Somehow the JSAI is now more advanced than the
MindForth AI, until we can port the new functionality
into Win32Forth.
