Categorization Generated by Prototypes – an Axiomatic Approach
نویسندگان
چکیده
We present a model of categorization based on prototypes. A prototype is an image or template of an idealized member of the category. Once a set of prototypes is defined, entities are sorted into categories on the basis of the prototypes they are closest to. We provide a characterization of those categorizations that are generated by prototypes.

Categorization generated by extended prototypes—An axiomatic approach
We suggest a model of categorization based on prototypes. A set of entities, identified with some finite dimensional Euclidian space, is partitioned into a finite number of categories. Such a categorization is said to be generated by extended prototypes if there is a set of distinguished entities, one for each category, such that the categorization is determined by proximity to these prototypic...
متن کاملWho is an Ideal Organizational Leader in Iran? Examining the Content, Structure, and Consequences of Iranian Implicit Leadership Theories (IILTS)
Implicit Leadership Theories (ILTs) are individuals’ perceptions of the traits and behaviors characterizing leaders. Four studies investigated the reliabilities and different types of validities for a scale developed to measure Iranian Implicit leadership Theories (IILTs). Study 1 used a qualitative method to extract the implicit theories of ideal leadership after interviewing 27 experts. The I...
متن کاملConceptual Spaces with Weighted Prototypes: An Application to Categorization
This thesis introduces a new integrated formalization of the conceptual spaces framework proposed by Gärdenfors. We extend the notion of conceptual space generated by a set of prototypes by adding a weight vector to each prototype. This will allow us to represent non-uniformly scaled concepts and, as a special case, partial concepts. We also present a novel Weighted Prototypes-Based Categorizat...
متن کاملAn axiomatic approach to soft learning vector quantization and clustering
This paper presents an axiomatic approach to soft learning vector quantization (LVQ) and clustering based on reformulation. The reformulation of the fuzzy c-means (FCM) algorithm provides the basis for reformulating entropy-constrained fuzzy clustering (ECFC) algorithms. This analysis indicates that minimization of admissible reformulation functions using gradient descent leads to a broad varie...
متن کاملToward an exploration of follower's implicit followership theories of Mashhad's large organizations using a qualitative approach
Followership is a developing paradigm in organizational behavior which focusesmainly on followers. The goal of this study is to explore follower’s implicitfollowership theories (IFTs) which entail an analysis of follower’s views andperception about followership. For this purpose, based on a phenomenologicalapproach, semi-structured interviews with employees of large public and privateorganizati...
