Theme One Program • Discussion 7

Posted on June 24, 2022 by Jon Awbrey

Re: Ontolog Forum • Alex Shkotin Re: Theme One Program • Exposition 4 AS: As we both like digraphs and looking at your way of rendering, let me share my lazy way of using Graphviz on one of the last … Continue reading →

Theme One Program • Exposition 5

Posted on June 23, 2022 by Jon Awbrey

Lexical, Literal, Logical Theme One puts cactus graphs to work in three distinct but related ways, called lexical, literal, and logical applications. The three modes of operation employ three distinct but overlapping subsets of the broader species of cacti. Accordingly … Continue reading →

Theme One Program • Exposition 4

Posted on June 20, 2022 by Jon Awbrey

Coding Logical Graphs It is possible to write a program that parses cactus expressions into reasonable facsimiles of cactus graphs as pointer structures in computer memory, making edges correspond to addresses and nodes correspond to records. I did just that … Continue reading →

Theme One Program • Exposition 3

Posted on June 17, 2022 by Jon Awbrey

Coding Logical Graphs My earliest experiments coding logical graphs as dynamic “pointer” data structures taught me that conceptual and computational efficiencies of a critical sort could be achieved by generalizing their abstract graphs from trees to the variety graph theorists … Continue reading →

Theme One Program • Exposition 2

Posted on June 16, 2022 by Jon Awbrey

The previous post described the elementary data structure used to represent nodes of graphs in the Theme One program. This post describes the specific family of graphs employed by the program. Figure 1 shows a typical example of a painted … Continue reading →

Theme One Program • Exposition 1

Posted on June 15, 2022 by Jon Awbrey

Theme One is a program for building and transforming a particular species of graph-theoretic data structures, forms designed to support a variety of fundamental learning and reasoning tasks. The program evolved over the course of an exploration into the integration … Continue reading →

Survey of Theme One Program • 4

Posted on June 12, 2022 by Jon Awbrey

This is a Survey of blog and wiki posts relating to the Theme One Program I worked on all through the 1980s. The aim was to develop fundamental algorithms and data structures for integrating empirical learning with logical reasoning. I … Continue reading →

Charles Sanders Peirce, George Spencer Brown, and Me • 16

Posted on January 15, 2022 by Jon Awbrey

Re: Conceptual Graphs • Gary Zhu GZ: I’m quite confused on why people are interested in Laws of Form. What is LOF trying to do? Is it just rewriting logic or is there something more fundamental. e.g. a universal algebraic … Continue reading →

Differential Logic, Dynamic Systems, Tangent Functors • Comment 2

Posted on November 6, 2021 by Jon Awbrey

Re: Differential Logic, Dynamic Systems, Tangent Functors • 1 Seeing as how quasi-neural models and the recurring issues of symbolic vs. connectionist paradigms have come round again, I thought I might revisit work I began initially in that context, investigating … Continue reading →
