Classically, unsupervised machine learning techniques are applied on data sets with fixed number of attributes (variables). However, many problems encountered in the field of informetrics face us with the need to extend these kinds of methods in a way such that they may be computed over a set of...

The process of assessing individual authors should rely upon a proper aggregation of reliable and valid papers’ quality metrics. Citations are merely one possible way to measure appreciation of publications. In this study we propose some new, SJR- and SNIP-based indicators, which not only take...

Different types of continuity of triangular norms are investigated. The types which are stronger than the usual continuity are analytical properties and, therefore, there are representations of the corresponding triangular norms. This is not the case for the weaker types of continuity (which are...

We consider a family of copulas that are invariant under univariate truncation. Such a family has some distinguishing properties: it is generated by means of a univariate function; it can capture non-exchangeable dependence structures; it can be easily simulated. Moreover, such a class presents...

The two-parts state-of-art overview of aggregation theory summarizes the essential information concerning aggregation issues. Overview of aggregation properties is given, including the basic classification of aggregation functions. In this first part, the stress is put on means, i.e., averaging...

In this second part of our state-of-the-art overview on aggregation theory, based again on our recent monograph on aggregation functions, we focus on several construction methods for aggregation functions and on special classes of aggregation functions, covering the well-known con- junctive,...

Recently, Maccheroni et al. [Maccheroni, F., Marinacci, M., 2005. A strong law of large numbers for capacities. Ann. Probab. 33, 1171–1178] have provided an extension of the strong law of large numbers of i.i.d random variables for capacities. In this paper, we formulate new versions of the...
