Modules, brains and schemas

Abstract

A short personal note briefly traces the author's interactions with Hartmut Ehrig. Where Ehrig has devoted much work to an algebraic theory of modules, the author has developed schema theory primarily as a tool for brain theory, but the author's version of schema theory has also been associated with algebraic theory and robotics. Topics presented in the present informal overview of schema theory include the role of schémas in bridging from action-oriented perception to knowledge, the notion of schema instances and their role in cooperative computation, learning in schemas, and ways of linking schemas to the study of the brain. © Springer-Ver lag Berlin Heidelberg 2005.
