Stubbing in MindMeld() and stopping derailment of thought.

We function now as an AI Mind Maintainer debugging the Perlmind free AI source code. In the ghost198.pl AI we first stub in the audacious MindMeld() module to nudge AI practitioners into devising a way for two AI Minds to share their dreams. Then we deal with some problems pointed out on Usenet by persons who have downloaded the Perlmind and evaluated its functionality.

We run ghost198.pl with "dogs are mammals" as input and we press the Escape-key to halt the AI after its first response, "I HELP KIDS". We notice immediately three problems with how the word "DOGS" is stored in the @psy and @ear memory arrays. For some reason, "DOGS" is being assigned new-concept #3002, even though the Tutorial display of diagnostic messages indicates that the AI is preparing to assign new-concept #3001 to the first new concept. We check the MindBoot() sequence to make sure that "DOG" is not already a known concept in the AI; it is not. Now let us inspect the source code to see where the new-concept number $nxt is incremented from 3001 to 3002. We see that the end of MindBoot() clearly assigns the number 3001 as the value of the $nxt variable. Now let us search for the $nxt++ increment. It is happening towards the end of the NewConcept() module. We immediately wonder if $nxt is being incremented before AudMem() stores the concept-number. We insert into AudMem() a diagnostic message to let us know the $nxt value before storage. The first diagnostic message does not tell us enough, so we insert a second diagnostic into the AudMem() module. It also does not help us.

In the AudInput() module we use some diagnostic messages to learn that the "S" in "DOGS" is first being stored with the correct $nxt value of "3001" and then a second time with the incorrect value of "3002". Perhaps we should increment $nxt not in NewConcept() but in AudInput(). We move the $nxt++ increment from NewConcept() into AudInput(), and we stop getting the wrong values of the $nxt variable.

A second problem is that the concept of "DOGS" is being stored with a zero instead of "2" for "plural" in the $num slot of the @psy conceptual flag-panel. The most recent incarnation of the InStantiate() module does not seem to address the $num value sufficiently, so let us inspect recent or older MindForth code. We discover that the obsolete 24jul14A.F version of MindForth uses some complex tricks to assign the num(ber) of a concept being stored, so we will put aside this problem to deal with more serious issues.

The third and presumably more serious problem is that the input word "DOGS" is being stored with the $nxt concept number "3001" only on the "S" phoneme and not on the "G" at the end of the word-stem "DOG". Let us leave that problem also aside for a while, because entering "dogs are mammals" repeatedly is running into more serious problems. FOr instance, all three words of the input are being stored erroneously with the same $rv recall-vector, which can cause the wrong auditory memories to be retrieved. Let us see if the previous ghost197.pl does the same error. Yes, and so does the ghost196.pl AI. However, we should not find it difficult to correct the $rv problem. We fix the problem by resetting $rv to zero at the end of the InStantiate() module. Now the Perlmind no longer goes off the rails of thought, and so we upload it to the Web.

Ghost Perl Strong AI cycles through Normal; Transcript; Tutorial; Diagnostic Mode

It is time now in ghost197.pl to show a clean human-computer interface (HCI) and to stop displaying masses of diagnostic messages. Accordingly in the AudInput module we change the user-prompt to say "Tab cycles mode; Esc(ape) quits AI born [date-of-birth]". We insert if-clauses to declare which user input mode is in effect: Normal; Transcript; Tutorial; or Diagnostic. Near the start of ghost197.pl we set the $fyi to a default starting value of unity ("1") so that the human user or Mind-maintainer may press the Tab-key to cycle among user input modes. In AudInput() we insert code to increment $fyi by one point with each press of the Tab-key and to cycle back to unity ("1") for Normal Mode if the user in Diagnostic Mode presses Tab again.

In the MainLoop module we change a line of code to test for $fyi being above a value of two ("2") and, if so, to display the contents of the @psy conceptual array and of the @ear auditory memory array. Thus the user in #3 Tutorial Mode or in #4 Diagnostic Mode will see the storage of current input and current output in the memory arrays. We consider the display of conceptual memory data in Tutorial Mode to be an extremely powerful tool for teaching how the artificial general intelligence (AGI) works. After any input, the user may see immediately how the input goes into memory and how the values in the flag-panel of each row of the @psy array represent the associative tags from concept to concept and from engram to engram.

Next we start commenting out or deleting the display of various diagnostic messages. Over time and over multiple releases of the Ghost AI source code, any AI coder may decide which messages to display in both Tutorial and Diagnostic Modes, or in only one of them. Although we comment out a message involving Russian input, we do not delete the diagnostic message because we may need it when we turn back on Russian as an input language. Russian has become much more important in our Ghost Perl AI because we need Russian or German to demonstrate Machine Translation by Artificial Intelligence. When we have commented out most of the diagnostic messages, we need to put back in some code to show what the user is entering.

Stubbing in the MetEmPsychosis module.

[2017-04-10] Today in ghost195.pl we stub in MetEmPsychosis() as an area for Perl code that will enable an AI Perlmind to either move itself across the Web or replicate itself across the Web. We foresee the advent of a kind of "AiBnb" or community of Web domains that invite and encourage AI Minds to take up temporary or long-term residence, with local embodiment in a robot and with opportunities for local employment as a specialized AI speaking the local language and familiar with the local history and customs.

[2017-04-10] In the AudInput() module today we insert the Cyrillic characters of the Russian alphabet for each line of code that converts lower case to upper case and sets the $hlc variable to "ru" as the human-language-code for Russian. We have not yet turned the Russian language back on again, but we will need it to test out our ideas for Machine Translation by Artificial Intelligence.

Coding VisRecog to say by default: I SEE NOTHING.

[2017-04-11] Today in ghost196.pl we would like to port in from MindForth the code that causes any statement of what the AI is seeing to default to the direct object "NOTHING," so that Perl coders and roboticists may work on integrating computer vision with the AI Mind. We make it clear that the visual recognition (VisRecog) system needs only to supply the English or Russian name of what it is seeing, and the AI will fill the slot for direct objects while generating a sentence about what the AI sees. The VisRecog mechanism does not need to be coded in Perl or in Forth. It only needs to communicate to the Perlmind a noun that names what the AI is seeing. When the generated statement passes through reentry back into the Mind, even a new noun will be assigned a concept-number and will enter into the knowledge-base (KB) of the AI.

First we declare the subject-verb-object variables $svo1, $svo2, $svo3, and $svo4 to hold a value that identifies a concept playing the role of subject, or verb, or indirect object, or direct object in a typical sentence being generated by the AI. If there is no direct object filling the slot for the object of the verb "SEE", then the VisRecog() module must try to fill the empty slot. Until a Perl expert fleshes out the VisRecog() code, the word "NOTHING" must remain the default object of the verb "SEE" when the ego-concept of "I" is the subject of the verb. We ran the AI and we typed in "you see kids." After a spate of outputs, the AI said, "I SEE KIDS," but we would really prefer for the AI to say, "I SEE NOTHING" as a default.

After coding a primitive VisRecog() module, next we go into the part of the EnVerbPhrase() module where it is looking for a direct object. We set conditions so that if the subject is "I" and the verb is "SEE", VisRecog() is called to say "NOTHING" as a direct object, and EnVerbPhrase() stops short of saying any other direct object by doing a "return" to the calling module. We now have a Perlmind that invites the integration of a seeing camera with the AI software.

Retroactively setting associative $seq tags for direct objects of verbs.

In the ghost194.pl AI, we have a problem where the direct-object $seq of a verb is being indeed properly assigned for human user input, but not for reentrant ideas being summoned from experiential memory. Because the $seq is not yet known when a verb comes in, the $seq value must be assigned retroactively when the direct object of the verb comes in. The situation where the process works for human input but not for a reentrant idea, suggests that the cause of the problem could simply be that the value of some pertinent variable is not being reset as needed.

This problem of the retroactive assignment of the associative $seq tag for a verb is difficult to debug. It may involve making the reentry routine equal to the human-input routine, or it may involve porting into Perl some special code from the 24jul14A.F version of MindForth. We have meanwhile been offering in the computer-science compsci subReddit a suggestion that students in need of an undergraduate research project might look into the Ghost AI software coded in Strawberry Perl 5 as an opportunity to select a mind-module to work on. We feel some urgency to debug our code and get it working as well as possible when we are inviting undergraduate students and graduate students and professors to take over and maintain their own branch of the AI Mind development. There is a steep learning curve to be surmounted before participants in such an artificial general intelligence (AGI) project may move forward in AI evolution. So now we go back to the problem of debugging the retroactive assignment of $seq subsequent-concept tags.

We search our ghost194.pl source code for "$psy[" as any instance where a $seq is being inserted either currently or retroactively into a flag-panel row of the @psy conceptual array. We discover that a $verbcon flag for seeking direct or indirect objects is governing the storage of the $seq tag in the Parser() module. Immediately we suspect that the $verbcon flag is perhaps being set during actual human user input but not during the reentry of an idea retrieved from memory. We check and we see that $verbcon is set to unity ("1") in the Parser() module when the part-of-speech $pos variable is at a value of "8" for a verb. The $pos value is set in the OldConcept() module when a known verb is recognized.

We insert a diagnostic message about the direct object in the Parser() module, and the message shows up during human user input, but not during reentry. Apparently the Parser() module is not even being called during reentry. No, it is being called, but the $verbcon flag is not being set properly during reentry. When we comment out the reset of $verbcon at the end of the AudInput() module and we move the reset to the Sensorium() module, we start seeing the assignment of direct-object $seq tags during the reentry of ideas recalled from memory. However, in a later session we must deal with the new problem that improper direct-object $seq flags are being set for personal pronouns during human user input. No, we debug the problem now, simply by resetting time-of-verb $tvb at the start of the EnThink() module, to prevent an output-sentence from adjusting associative tags for a previous sentence with a previous time-of-verb. The AI becomes able to receive "i know you" as input and then somewhat later say "YOU KNOW ME."
