Skyline queries are a popular and powerful paradigm for extracting interesting objects from a d-dimensional dataset. They rely on Pareto dominance principle to identify the skyline objects, i.e., the set of incomparable objects which are not dominated by any other object from the dataset. Two main problems may be faced when using skyline queries: (i) a small number of returned objects which could...
This paper focuses on the definition and measurement of quality of work (QoW) using a multidimensional approach, based on fuzzy logic. The multidimensional nature of quality of work has been widely acknowledged in economic and sociological literature and attempts at measuring its different dimensions can be found at European level in the work carried out by the European Foundation for the Improvement...
Purpose of this work is to develop norms, knowledge and algorithms that will make a real shift most of the educational process on the computer environment. On the basis of artificial neural networks, a mechanism, which allows taking into account, the subjective opinion of experts without requiring changes to the system. With the help of fuzzy logic developed an original method of monitoring the student's...
A large number of non-dominated fuzzy rule-based classifiers are often obtained by applying a multiobjective fuzzy genetics-based machine learning (MoFGBML) algorithm to a pattern classification problem. The obtained set of non-dominated classifiers can be used to analyze their accuracy-interpretability tradeoff relation. One important issue, which has not been discussed in many studies on MoFGBML,...
Space-time causality is one of the fundamental notions of modern physics; however, it is difficult to define in observational physical terms. Intuitively, the fact that a space-time event e = (t; x) can causally influence an event e′ = (t′, x′) means that what we do in the vicinity of e changes what we observe at e′. If we had two copies of the Universe, we could perform some action at e in one copy...
