parallel distributed processing

PDP (parallel distributed processing)

an attempt to simulate a cognitive process by the interaction of a number of simple processing units that could be linked to neurons

Jeffrey Hinton

considered to be the “god father of AI”

Jay McClelland

equally important to parallel distributed processing and AI

Seidenberg & McClelland

developed a model of reading aloud

Seidenberg & McClelland Model

based on simple processing units that learn associations between inputs and outputs

words are associated with:

• orthographic units (spelling/letters)

• phonological code (sound)

• semantic units (meaning)

process as a computer program

simulates reading aloud with sophisticated representations for all levels

• orthography

• phonology

• semantics

input and output meaning

input: visual unput (letters of a word)

output: phonological code (used to drive pronunciation)
