Actions and Speciicity

Object Recognition: View-speciicity and Motion-speciicity

This paper describes an experiment to distinguish between two theories of human visual object recognition. According to the view-speciicity hypothesis, object recognition is based on particular learned views, whereas the motion-speciicity hypothesis states that object recognition depends on particular directed view-sequences. Both hypotheses imply a degree of view-bias (i.e. recognition of a gi...

On Speciicity in Default Logic

The applicability of lexicographic comparison in nonmonotonic reasoning with speciicity is investigated. A priority mechanism based on lexicographic comparison is deened for Reiter's default logic. The following principle earlier used by Geener and Pearl in conditional entail-ment is used as the basis for speciicity-based priorities for normal default theories: for each rule there is a context ...

Cepstral Statistics within Phonetic Subgroups

The identiication of aspects of cepstral features that contain a high degree of speaker speciicity potentially can simplify the task of speaker recognition. The identiication process can be performed both temporally and cepstrally. The temporal analysis determines which phonemes or utterances exhibit the highest degree of speaker speciicity, while the cepstral analysis examines individual cepst...

Computing Speciicity in Default Reasoning

Objects, Speciicity, Logic, and Chance

Recent deductive approaches to reasoning about action and chance allow to model objects and methods in a deductive framework. In these approaches, inheritance of methods comes for free whereas overriding of methods is unsupported. In this paper , we present an equational logic framework for objects, methods, inheritance and overriding of methods. Overriding is achieved via the concept of specii...
