Interactive Activation Theory Models
-
An interactive activation model of context effects in letter perception...,
by McClelland and Rumelhart Psychological review (1981), is one
of the IAT papers. Note it's 7000 citations while GPS just has 1000.
- The idea is that different concepts interact with other concepts.
- Activation is spread between them.
- The Sharks and Jets is an easy example.
- In this case you set up the weights to the middle nodes, for example
with Lance being in his 20s, having graduated High School and being
a jet. If you turn on Jet, Lance and the other Jets will come on.n
- The paper above deals with letter and word recognition, and
duplicates a fair few results from people.
- There are a whole bunch of IAT spreading activation models from the
80s. I use some work from Patty Maes on planning to do this in my
spiking neural agents.
