Abstract One way to theorize about we-identities—the identities that individual subjects have as ‘one of us’—is in terms the uniformity, interchangeability, and prototypicality group members. The social-psychological theory self-categorization epitomizes this approach, which has strongly influenced contemporary phenomenological research on we. This paper argues approach one important largely ov...

Modeling serial order effects, meaning exemplars are presented one at a time and the order of presentation affects the results subjects produce, would introduce additional constraints on our clustering algorit...

We extend Leeuwenberg's Structural Information Theory (SIT) to an algebraic framework, where domain-dependent operators are allowed to become part of the perceptual gestalts. Using the SIT notion ofìnforma-tion load', we provide a structural notion of similarity and categorization. We introduce two complexity measures , namely descriptor complexity and member complexity , which drive categoriza...

Purpose – We describe an intelligent video categorization engine (IVCE) that uses the learning capability of artificial neural networks (ANNs) to classify suitably preprocessed video segments into a predefined number of semantically meaningful events (categories). Design/methodology/approach – We provide a survey of existing techniques that have been proposed, either directly or indirectly, tow...

Categorization is a primary application for conceptual knowledge stored in the human brain. Categorization is often based on similarity, involving apparent use of both prototypes and stored exemplars. Some human categorization appears to be rule or theory based rather than based on similarity. Attempts to model categorization often involve multiple subsystems to support the different observed a...
