A Novel Similarity Measure for Heuristic Selection in Examination Timetabling
Metaheuristic approaches to examination timetabling problems are usually split up into two phases: initialisation phase in which a heuristic is employed to construct an initial sol...

Image segmentation by histogram thresholding using fuzzy sets
Methods for histogram thresholding based on the minimization of a threshold-dependent criterion function might not work well for images having multimodal histograms. In this paper ...

Homomorphisms of Fuzzy Logic Models Based on Sets With Similarities
We investigate interpretations ψ D of formulas ψ in a first order fuzzy logic in models D which are based on Ω-sets, i.e. sets with similarity relations with values in a comp...

The Frank t-norm family in fuzzy similarity measurement
A family of fuzzification schemes is proposed that can be used to transform cardinality-based similarity measures for ordinary sets into similarity measures for fuzzy sets in a fi...

On the number of principal components: A test of dimensionality based on measurements of similarity between matrices
An important problem in principal component analysis (PCA) is the estimation of the correct number of components to retain. PCA is most often used to reduce a set of observed vari...
