Theme One Program • Motivation 2

A side-effect of working on the Theme One program over the course of a decade was the measure of insight it gave me into the reasons why empiricists and rationalists have so much trouble understanding each other, even when those … Continue reading

Theme One Program • Motivation 1

The main idea behind the Theme One program is the efficient use of graph-theoretic data structures for the tasks of “learning” and “reasoning”. I am thinking of learning in the sense of learning about an environment, in essence, gaining information about … Continue reading

Theme One • A Program Of Inquiry 15

An unexpected benefit of cleaning out our basement and putting our belongings in storage was finding a trove of work I thought I’d lost, in a stash of 3½ inch floppies, no less.  I uploaded a sample to a couple of folders … Continue reading

Theme One • A Program Of Inquiry 14

As an alternative to piling generalities on generalities, not that there’s anything wrong with that, it also helps to look at issues as they arise in concrete applications. One of the most concrete applications I ever attempted was the program … Continue reading

Definition and Determination • 17

Re: Ontolog Forum • Richard McCullough RM:  We clearly have some differences in the “definition” of “definition”. I suppose it all depends on the sorts of things one wants to define, something we might call the context of application.  I am … Continue reading

Definition and Determination • 16

Re: Ontolog Forum • Richard McCullough RM:  What is your view of definitions? A recurring question, always worth some thought, so I added my earlier comment to a long-running series on my blog concerned with Definition and Determination. Survey of Definition … Continue reading

Definition and Determination • 15

Re: Ontolog Forum • Richard McCullough In some early math course I learned a fourfold scheme of Primitives (undefined terms), Definitions, Axioms, and Inference Rules.  But later excursions tended to run the axioms and definitions together, speaking for example of … Continue reading

Theme One • A Program Of Inquiry 13

Logical Cacti (cont.) The abstract character of the cactus language relative to its logical interpretations makes it possible to give abstract rules of equivalence for transforming cacti among themselves and partitioning the space of cacti into formal equivalence classes.  The … Continue reading

Theme One • A Program Of Inquiry 12

Logical Cacti (cont.) The main things to take away from the previous post are the following two ideas, one syntactic and one semantic. The compositional structures of cactus graphs and cactus expressions are constructed from two kinds of connective operations. There are … Continue reading

Theme One • A Program Of Inquiry 11

The portions of exposition just skipped over covered the use of cactus graphs in the program’s learning module to learn sequences of characters called “words” or “strings” and sequences of words called “sentences” or “strands”.  Leaving the matter of grammar … Continue reading
