Short: Project Mentifex's Arexx based AI design Uploader: vedovatt@u.washington.edu Author: uj797@freenet.victoria.bc.ca (Arthur T. Murray) Type: util/rexx Readme29APR94 for Mindrx940429.lha Amiga AI public-domain work-in-progress. The REXX programs in this archive are an attempt to implement in software the linguistic theory of mind found as text and a "Mind.anim" on the Amiga Library Disk (Fred Fish) No. 411. These work-in-progress postings are being made by Arthur T. Murray of Project Mentifex in Seattle, Washington. I am the author of Mind.rexx and I hereby release the version in this posting into the public domain. The version "Mind29APR94A" permits the creation of various diagnostic and archival records, such as hardcopy "labnote" print-outs of Mind.rexx sessions, and RAM files containing the detailed state of the conceptual memory and of the auditory memory at the end of a Mind.rexx session. Persons who obtain and examine Mind.rexx are invited to choose the hardcopy option and to mail the resulting "Field Report" to Project Mentifex, Post Office Box 31326, Seattle, WA 98103-1326 before the end of September 1994. "Mind29APR94A" demonstrates the "quickening" of the Mind.rexx program. Today we have pulled out all the stops (the requests that the user press the key) and we have programmed Mind.rexx to check briefly for user input - in the absence of which, Mind.rexx goes into its "THINKING" mode and formulates a simple sentence. However, we have only barely begun to implement the internal associative processes of the rexxmind, as is evident from the poor linguistic performance that results. This version is nevertheless being released immediately because it is the first version that actually does anything. Mind.rexx now interacts with the user and responds to user input. Much work remains to be done, but the very release of this program is an invitation, for anyone who wishes, to work on the Mind.rexx code to create artificial intelligence (AI). Some sample "mindlog" and "audlog" files are included in this archive. The audlog file shows a stream of auditory memory in which a "+" sign indicates reactivated engrams brought forward from the past, and the "@" sign indicates current input from an external source at the time "t". The "+" memories may well reflect the first stirrings of Mind.rexx as a machine intelligence. The "AudInPut" program is the rudimentary implementation of our present plan to isolate the Mind.rexx from direct human input and to let the rexxmind think on its own, after spawning a separate REXX program which the human operator may use as an independent channel of communication with the main Mind.rexx AI. The need for such isolation arose from the programming consideration that the rexxmind should not have to wait idly for human input, but should be allowed to think independently while checking constantly for human input. We have opted to use the Amiga ARexx "Clip List" as the message-passing mechanism, rather than an external file, so as to keep the mental structures tightly within ARexx and not loosely out in the vicissitudes of the operating system. As an afterthought, it occurs that multiple co-existing rexxminds may pass messages through the Clip List, or one single rexxmind may poll Clip List message-names for not only auditory input, but also visual and other sensory input. Mind.rexx simulates massive parallelism by letting all internal flows of information advance by only one single step during a single moment "t" of time. The program relies on its speed of computation in its attempt to keep up with real-time input. During a frozen moment "t" of time, Mind.rexx will generate an entire sentence of thought in natural language and then deposit the sentence as engrams in the auditory memory channel over an appropriate span of moments commensurate with the length of the sentence. Although with use of the Clip List and of other uniquely Amiga REXX features we are risking a non-portability of Mind.rexx, our primary concern is first to create the artificial mind on the Amiga, verify that it works (thinks), and then re-code Mind.rexx for portability. Even while still on the Amiga platform, the construction of Mind.rexx as a group of intercommunicating mental "modules" makes possible our invitation for any interested ARexx programmer to work on the implementation of specific modules such as: visual input and the visual memory channel; speech-recognition for a truly phonemic auditory channel; the motor memory channel leading to robotics; emotion; volition; pain/pleasure; and so forth. No permission from Project Mentifex is necessary, and no objection from any authority is tolerable: The making of minds already occurs every day when parents have children. The modules of mind are apparent in the Main Body "Mindgrid" loop which calls the modules one by one as Mind.rexx functions. REXX programmers are invited to substitute their own programming code to improve a module. Further public-domain implementation of Mind.rexx will be sought for the following non-Amiga versions of REXX: uni-REXX VX-REXX The Workstation Group WATCOM International 6300 N.
