Parallel Distributed Processing: Explorations in the Microstructure of Cognition

Introduction

Parallel Distributed Processing (PDP) is a computational approach inspired by the human brain, emphasizing the parallel processing of information across interconnected units. This model stands in contrast to traditional serial processing, which involves sequential steps. PDP has been instrumental in understanding complex cognitive phenomena, such as learning, memory, and perception.
