John - interesting outline - and I'd need to spend a lot more time
on it. At a quick glance, slide 41 seems to fit into the Peircean
three categories with 'unsupervised learning'; 'reinforcement
learning' and 'supervised learning'.

I completely agree.
For any audience, it's important to start with terminology that is
familiar to the audience. But when talking about any source, it's
best to quote the ipsissima verba of the author(s).
As an example, I'm still working on and extending the slides for a
talk
I presented in July 2016 on "The virtual reality of the mind". That
was
for a conference whose participants had a strong background in AI
and
neuroscience. So I started with those two subjects and presented
Peirce's semiotic as the unifying framework for organizing and
relating
research in those two fields. Before getting to Peirce, I started
with terminology and examples that the audience was familiar with.
See http://www.jfsowa.com/talks/vrmind.pdf [1]
The full presentation is rather long (112 slides), but Just look
at three slides to see the point:
Slide 45 describes an experiment that shows how physics instruction
changes neural representation. I describe the study briefly and
include the URL of the full publication.
Slide 46 shows three fMRI images of neural activity in the brain of
the
students. And it uses the same terminology as the original
publication.
(See a copy below.)
Slide 57 shows exactly the same three images as slide 46, but it
describes the neural activity in terms of Firstness, Secondness, and
Thirdness.
As far as I know, this is the first example that shows neural
correlates
of Peirce's three categories. If anyone knows of any other
examples,
I would love to see them.

Slide 46: Cognitive Learning
Neural activity in the right hemisphere during test sessions:
● All 14 students showed similar neural activations.
● Questions about the objects and parts activated the visual
cortex,
the occipital lobes in the back of the brain (image #1).
● Questions about structural relations activated the parietal
lobes,
which link vision to all sensory and motor regions (image #2).
● Questions about the causal effects of someone operating the
system
activated the frontal lobes and connections across the brain
(image #3).
● Summary: Cognitive learning involves structural and causal
relations
that link and coordinate perception, action, and reasoning.
Slide 57: Neural Correlates
Neural correlates of Firstness, Secondness, and Thirdness:
● Perception is based on localized percepts or prototypes. It
classifies phenomena by the monadic predicates of Firstness
(fMRI image #1).
● Long-distance connections in the parietal lobes support dyadic
relations that connect all sensory and motor modalities. They
represent the structures of Secondness (image #2).
● The frontal lobes process the mediating Thirdness in reasoning,
planning, causality, and intentionality (image #3).
● Much more detail must be analyzed and explained, but the
examples
in slides 45, 46, and this one illustrate promising directions to
explore.
