Joseph Peters
Bio [2004]
Joseph Peters graduated as an English major from Dartmouth College in
1999. Since then he has been in a variety of jobs involving some
combination of web design and writing, including doing some web design
for the Howard Dean campaign. His interests are quite varied but
include chat bots, the Turing test, the history of near misses of the
NKS discovery, and the structure and use of language.
Project Title
Learning the Past Tense of English Verbs, Part
Deux
Project
In brief: selecting simple rules that will distinguish between
different types of verbs and conjugate them accordingly. Turing once
suggested that one of the best tests of a human-like intelligence
would be the proper use of language. This theory has come to be known
as the "Turing test." In 1982, cognitive scientists McClelland and
Rumelhart took an important step toward this ideal by designing a
network system that could learn and express the past tenses of
English verbs. I will repeat this experiment, using a simple system
suggested in the NKS book, to observe what rules are generated by the
system when it encounters unfamiliar verbs. The process is described
below.
- Build a list of 200 verbs represented in their present and past
forms. Store the associated phonemes.
- Build a word-comparison program to generate symbols for each
category of verb.
- Expose the system to a new set of verbs, observing which rules are
generated and their success rates.
Favorite two-color, radius-2 rule
Rule chosen: 2121212121
My favorite CA is rule 2121212121--not just for its near-palindrome
title, but for its appearance as well.
