A k-dissimilarity D on a finite set X, |X| ≥ k, is a map from the set of size k subsets of X to the real numbers. Such … (<CitationRef CitationID="CR19">2004</CitationRef>) recently posed the following question: Given an arbitrary k-dissimilarity, how … ≥ 3 a k-dissimilarity on a set X arises from a tree if and only if its restriction to every 2 k-element subset of X arises …

We define a segregation ordering as a ranking of cities from most segregated to least segregated. \ We propose a set of basic properties that any reasonable segregation ordering should have. \ We then fully characterize the class of segregation orderings that satisfy these basic properties. \ We...

Many content-based recommendation approaches are based on a dissimilarity measure based on the product attributes. In … this paper, we evaluate four dissimilarity measures for product recommendation using an online survey. In this survey, we … dissimilarity measures with. Also, we use this matrix to estimate weights to be used in the dissimilarity measures. In this way, we …

We discuss a unified approach to the description and explanation of life course patterns represented as sequences of states observed in discrete time. In particular, we study life course data collected as part of the Dutch Fertility and Family Surveys (FFS) to learn about the family formation...
