Sun.26.SEP.2010 -- Reducing Calls to PsiDamp
Today into MindForth Robot AI we have inserted diagnostic code to announce each time that the PsiDamp mind-module is called, and which other mind-module is calling it. We are trying to suppress stray activations, and we do not want the PsiDamp module to interfere with the normal process of spreading activation.
The AudInput module seems to call PsiDamp from two
locations. The call from the second location (during
external input) may not be necessary, because it seems to
be just a way of knocking down the cresting concept. We
should perhaps not even think of a concept as "cresting"
during external input, but only during internal generation
of a thought. So let us try commenting out not only the
AudInput second call to PsiDamp, but also the nearby call
to VerbClip. Oops. When we comment out the second call to
PsiDamp, we stop getting a correct answer from the AI when
we ask "what am i". We get "YOU ARE YOU" instead of "YOU
ARE MAGIC". So we re-enable the call to PsiDamp.
Now let us try commenting out or conditionalizing a
call from NounPhrase to PsiDamp. Let us require
the "urpsi" to be a value above zero, so that PsiDamp does
not get called in vain. Actually, the fp091124.html MFPJ
entry explains that that call to PsiDamp did not seem to
improve anything at all. Apparently it was a defective
call to PsiDamp, because no "urpsi" was declared as the
concept to be psi-damped. Therefore let us simply comment
out that useless call to PsiDamp.
Next we were starting the AI and entering "i am stuff"
to give the AI something new to retrieve from the KB for
a "what am i" query. The AI kept answering only "YOU ARE
MAGIC". Then it dawned on us that we had so many new calls
to PsiDecay, that maybe inhibition of "-15" in NounPhrase
was not enough. So we switched to "-32" inhibition and we
received better results.

Human: i am stuff Robot: STUFF WHAT IS STUFF
Human: what am i Robot: YOU ARE MAGIC
Human: what am i Robot: YOU ARE A STUFF
It turns out that the word "MAGIC" still had a negative
activation from inhibition and so had to permit "STUFF" to
Upshot: With some success, the
MindForth AI is now able to answer both "what am i"
and "what are you" queries, retrieving multiple tidbits
from the knowledge base (KB) for each line of inquiry.
However, there is still some confusing of the "I"
and "YOU" concepts. Sometimes the AI ascribes the wrong
attribute (predicate nominative) to either "I" or "YOU",
and sometimes the AI simply says "YOU ARE I". Sometimes
the AI fails to retrieve all the available tidbits. There
is much room for improvement, but we now have some good
code which we should upload after commenting out the
