Ameva: An autonomous discretization algorithm
(ScienceDirect, 2009-04)
This paper describes a new discretization algorithm, called Ameva, which is designed to work with supervised learning algorithms. Ameva maximizes a contingency coefficient based on Chi-square statistics and generates a ...

The intentional relationship of representation between the constructs of a language and reality
(Elsevier, 2009)
Specifications of conceptualisations (ontologies) are often employed for represent- ing reality, both in knowledge representation and software engineering. While lan- guages o®er sophisticated constructs and rigorous ...

A new approach to qualitative learning in time series
(ScienceDirect, 2009-08)
In this paper the k-nearest-neighbours (KNN) based method is presented for the classification of time series which use qualitative learning to identify similarities using kernels. To this end, time series are transformed ...
