\title{Connectionism} \author{Patrick Juola} \begin{document} \maketitle \begin{abstract} Connectionist networks, also called ``neural'' networks, are the outgrowth of an attempt to produce human-like behavior by modelling the architecture of the human brain. This is a radical departure from traditional rule-and-object formalisms of the sort that most linguists are familiar with, but may produce some better results in capturing regularities (and processes) in the human language system. This chapter summarizes some of the mathematics underlying common connectionist systems and shows how these systems have been deployed to a variety of linguistic problems. It tries to illustrate both how connectionism can be helpful as an explanatory and exploratory aid, and also some of the pitfalls of blindly applying connectionism without understanding its weaknesses. \end{abstract} \end{document}
