Using #CactusGraphs or #MinimalNegations to implement pools of #MutuallyInhibitoryNeurons erects #NeuralArchitectures on substantially different foundations from current #Connectionist models. At a high level of abstraction, however, there is enough homology between the 2 orders to compare their performance on many of the same tasks. Thus I was able to try the program on a few examples suggested by #McClelland & #Rumelhart.

Given a representation of the Jets & Sharks universe in computer memory, we naturally want to see if the memory serves to supply the facts a well-constructed #DataBase should.

In their #PDPHandbook presentation of the Jets & Sharks example, #McClelland & #Rumelhart give several exercises for exploring the use of their #NeuralPool #MemoryModel on tasks of #Retrieval & #Generalization.

Our #CactusGraph bears a vocabulary of \(41\) #LogicalTerms, each denoting a #BooleanVariable, so our proposition, call it \(``q",\) is a #BooleanFunction \(q:\mathbb{B}^{41}\to\mathbb{B}.\) Since \(2^{41}=2,199,023,255,552,\) its #TruthTable has \(>\) 2 trillion rows and its #VennDiagram has that many cells. There are \(2^{2^{41}}\) functions \(f:\mathbb{B}^{41}\to\mathbb{B}\) and \(q\) is just one of them.

As we saw last time, Theme One reads the text file shown below and constructs a #CactusGraph #DataStructure in computer memory. The cactus graph represents a single #LogicalFormula in #PropositionalCalculus which embodies all the #LogicalConstraints defining the Jets and Sharks #DataBase.

The manner of representation may be illustrated by transcribing a well-known example from the #ParallelDistributedProcessing literature (#McClelland and #Rumelhart 1988) and working through a couple of the associated exercises as translated into #LogicalGraphs.

One way to do this is to interpret the blank or #UnmarkedState as the #RestingState of a #NeuralPool, the bound or #MarkedState as its #ActivatedState, and to represent a mutually inhibitory pool of #Neurons \(a,b,c\) by the proposition \(\texttt{(}a\texttt{,}b\texttt{,}c\texttt{)}.\)

The #PropositionalCalculus based on #MinimalNegationOperators can be interpreted in a way resembling the logic of #ActivationStates and #CompetitionConstraints in one class of #NeuralNetwork models.

In developing the Theme One Program I tested successive versions of its #InferenceEngine for #PropositionalCalculus #ConstraintSatisfaction on examples of #Logic problems current in the literature of the day. #McClelland and #Rumelhart's #PDPHandbook set one of the wittiest gems ever to whet one's app-titude so I could hardly help but take it on. The linked text is a light revision of the way I set it up in the program's User Guide.
