The Ray Brain Model for AI Applications
Pattern Synthesis
All patterns are not remembered sets of data. New patterns can be created by the system, from parts duplicated from previously stored patterns. Elements can be "subtracted" from one pattern and "added" to others. Thus we have two components here--"the pattern ADDER" and the "pattern SUBTRACTOR".
As there is a pattern for everything the brain knows there will be, in storage, a pattern that "matches" the element that is to be extracted or added to a pattern in the adder or subtractor buffers. the matching elements are either removed from the pattern in the buffer or added to it, depending upon the operation desired. the result is a NEW pattern, which will ALSO be stored in the "Stack" along with the remembered process used to create it.
Another pattern synthesizer is what we can call the "AND-ER". The operation of this element can be directly observed in the reader?s brain. The reader, for example, may think of a series of people he knows. They may be a "Joe", "Mary", "Bill" that is known. Each name "calls up" a separate pattern. BUT if we insert the word "AND" into this list, something happens---- "Joe, Mary and Bill" become a NEW pattern containing the duplicated elements of the three former patterns. That the word "AND" makes us think of the people as a group, rather than individuals, is evidence that a new pattern was created.
The function of the "Ander" reveals an important connection between LANGUAGE and brain function. the word "and" is directly associated with the internal function that combines the data of several patterns into one. This holds true for the "Adder" and "Subtractor" components also, but as more words are involved, the effects might not as be as obvious as in the "Ander". This suggests that the Brain uses what can be called a "BASAL LANGUAGE". That is, certain brain functions are directly associated with certain words learned by the system.
Other words can also affect brain function. "Plus", for example, may function as "and", but "And", being the FIRST word learned by the system is "basal" while "Plus" is not. "Plus" triggers the "Ander" only because it is ASSOCIATED with being "another word for 'and'" which , in turn activates the "Ander". Therefore, the brain's "Basal Language" consists of only those words that are the FIRST learned by the system that are directly associated with a brain function or a special pattern called a "concept". Other, later learned, words are simply associated with equivalent words learned previously and the line of associations may ultimately "link" to a "Basal" word. Basal words are important as the brain's operational sequences are "written" in them.
Sequence Building
The most obvious brain function is the building of sequences of thought and action that is carried out by the brain's owner. This takes place on what I call "the Primary Sequence Assembly Rack" (PSAR). The PSAR has at its "top" a "goal buffer", which holds a pattern that represents the situation that the brain desires to be in. At the "bottom" of the rack is the "PLS buffer". The "PLS" or Present Logical Situation, is the pattern that the brain system uses to represent its perceived present status and location. The brain's "problem" is, therefore, to build a continuous sequence of patterns, that will define "step by step" actions to get from the PLS buffer to the Goal buffer, and then carry them out.
It appears that the patterns contained within the PSAR and the associated brain functions represent what Psychologists call the CONCIOUS MIND. It contains the MAJOR steps (patterns) needed to proceed from the PLS to the Goal. But there are also MINOR "steps" in BETWEEN these major steps which are sequences unto themselves. These "minor steps" must also be assembled into sequences. For this yet another sequence assembly rack is needed. Here the pattern steps between the major steps in the PSAR are assembled. We can call this rack the "L-2" (Level 2) "rack". Still, there are yet other steps between the minor steps of the L2 rack, so an L3 rack is needed----and so on until the actions are "pure machine language" functions--at about the L6 or L7 level. The "racks" below L2 can be considered the "Sub-conscious Mind".
An illustration of the above can be the following example. The reader may suddenly decide that he is thirsty. He knows that there is a cool beer in the fridge in the Kitchen. Thus drinking that beer becomes the "goal". The PLS is that the reader is sitting on a chair in the computer room. He must 1: Get out of the chair 2: walk to the kitchen 3: Open the fridge 4:drink the beer.--these comprise the major steps in the PSAR (L-1) . L-2 steps might include 1: Push chair away from desk 2: Stand up 3: walk 10 feet to right 4: turn left. . . You get the Idea. L-3, for example, would include instructions on how to push away from the desk. At the "deepest" levels will be instructions for tensioning individual muscles--almost a pure machine or digital code.
At this point we can address the true nature of what we call "pain" and how pain controls the system. As the major steps in the PSAR are accomplished, one by one, they, in effect, become the PLS and there are fewer and fewer "steps" to execute in order to reach the goal. However, not ALL the steps in the sequence will be able to be carried out as is planed. When the result of an action does not result in moving to the next step, the sequence must be altered--in effect, a new PLS, the undesired result, is entered into the sequence, causing a new sequence to have to be built to the goal. The errant sequence is thus "flagged" or "pain keyed" so it will not be used again or "avoided"-----This is the very essence of "pain", although we are most familiar with pain in the "emotional" or "physical" aspect, the effects are IDENTICAL upon the system. The physical "ouch" pain, for example is our signal that a NEW PLS is being FORCED into the sequence----causing a reconstruction of a new sequence and a flagging of the previous sequence. Thus pain, in its functional sense, is a forced reconstruction of an existing racked sequence.--which may or may not actually "hurt".
