MindForth Programming Journal -- 2011 April 25

We may shift our attention away for a time
from the treatment of English articles and
concentrate instead on further work in the
implementation of neural inhibition.
Tues.26.APR.2011 -- Linking Subject with Related Knowledge.
One of our techniques for learning what to
do next in MindForth artificial intelligence
(AI) is to run the program and check to see
what is the most glaring problem that we
encounter. Currently we notice that the AI
fails at first (but only at first) to retrieve
its own self-knowledge when we prompt such
retrieval by entering "you" or "you are".
The AI has been answering "I AM I", which
shows a failure to activate "ANDRU" as the
name of the AI, or "PERSON" and "ROBOT" as
nouns which should come to mind when the
robotic person thinks about itself.
MindForth is already a so-called "artilect"
of sufficient mental complexity that the AI
is not stuck in a rut of answering "I AM I"
interminably when called upon to describe
itself. The mechanisms of neural inhibition
prevent more than a few instances of "I AM I"
and enable the mind-in-software to generate
"I AM PERSON" and "I AM ROBOT" as responses
more to our liking. We need to know, however,
why the AI initially makes the error of
repeating "I AM I" a few times before inhibiting
the unwanted response and before generating the
more informative responses.
Our initial troubleshooting indicates that
entering "you" as input to the AI properly
activates the "I" concept so that the AI can
at least utter "I AM I" in faulty response,
but obviously the software mindgrid is not
letting go of the "I" concept quickly enough to
let a noun like "ROBOT" or "PERSON" complete
the response. The problem may seem like a
simple issue of setting activation-levels for
concepts in the AI, but many of the settings
are interdependent within the totality of the
AI program.
We must keep in mind some special techniques
for troubleshooting the AI Mind behavior.
We may examine older versions of MindForth
to see not only if the problem was absent
in the past, but also when and why the
problem emerged. We have also the option of
running the JavaScript version of the same
AI Mind to see if the same problem is present.
We also have extreme options like making the
AI program halt at any stage in its thinking.
When we test MindForth by inserting a "QUIT"
command into the BeVerb module just after the
calling of the VerbAct module, we discover
that nouns like "ANDRU" and "ROBOT" and
"PERSON" are all left with only twenty-three points
of activation, while the "I" concept has thirty-nine
points. Further testing shows us that the
InStantiate module is setting an "act" of
forty (40) just after speaking the "I" pronoun.
Therefore, even if the concept of "I" is initially
psi-damped, the ReEntry process leaves
the "I" concept with an activation of forty.
We solve the current problem of failure to link
subjects with related knowledge by inserting into
the InStantiate module a test to set conceptual
activations to zero during the ReEntry of
concept-words that have just been thought.
