COMPOSITIONALITY - A CONNECTIONIST VARIATION ON A CLASSICAL THEME

Abstract

Connectionism has been attacked on the grounds that it does not employ compositionally structured representations (e.g., Fodor & Pylyshyn, 1988). This article develops the response that Connectionist models can, and in fact sometimes do, employ compositionally structured representations without, thereby, simply implementing a Classical "Language of Thought." Focusing on the mode of combination employed in constructing representations, it distinguishes concatenative compositionality, essential to the Classical approach, from a merely functional counterpart increasingly common in Connectionist research. On the basis of this distinction it is possible to demonstrate that Connectionist represent..
