In this paper we introduce the semi-uninorm based ordered weighted averaging (SUOWA) operators, a new class of aggregation functions that, as WOWA operators, simultaneously generalize weighted means and OWA operators. To do this we take into account that weighted means and OWA operators are particular cases of Choquet integral. So, SUOWA operators are Choquet integral-based operators where thei...

A popular interpretation of the Rational Expectations/Efficient Markets hypothesis states that, if it holds, market valuations must follow a random walk; hence, the hypothesis is frequently criticized on the basis of empirical evidence against such a prediction. Yet this reasoning incurs what we could call the ‘fallacy of probability diffusion symmetry’: although market efficiency does indeed i...

The concept of universal integral, recently proposed and axiomatized, encompasses several integrals, including the Choquet, Shilkret and Sugeno integrals. In this paper we present two new axiomatizations of universal integrals on the scale 1⁄20;1 . In the first characterization, we look at universal integrals on the scale 1⁄20;1 as families of aggregation functions F satisfying some desired pro...

Interconnecting machine readable data with multimedia assets and fragments has recently become a common practice. But specific retrieval techniques for the so called Semantic Multimedia data are still lacking. On our poster we present SPARQL-MM, a function set that extends SPARQL to Media Fragment facilities by introducing spatiotemporal filter and aggregation functions.

The aim of this contribution is to find a common framework for parametric characterization of aggregation functions exploiting the notions of unipolar and bipolar parametric characterization, and also unify the ideas of global and local parametric characterization. We revise the known approaches to classification of aggregation functions in special classes in this framework, and also propose so...

This paper presents a synthesis on the essential mathematical properties of Choquet and Sugeno integrals viewed as aggregation functions. Some axiomatic characterizations are presented. Subfamilies of the class of those integrals are also investigated.

We introduce a new model of aggregate information cascades where only one of two possible actions is observable to others. Agents make a binary decision in sequence. The order is random and agents are not aware of their own position in the sequence. When called upon, they are only informed about the total number of others who have chosen the observable action before them. This informational str...

in this paper, by using dynamic stochastic general equilibrium, optimal monetary rule derived for central bank of iran. monetary transmission mechanism of the model includes four equations, aggregate demand, aggregate supply, oil price and taylor rule. we have proved that dynamic structure of aggregate demand relation, regarding monetary inflation in iran, is a function of money growth rate. wi...

The article deals with economic convergence, which has long been one of the most important issues in field economics. aim study is to identify factors determine convergence voivodships, i.e. provinces (and more specifically, responsible for regional differentiation GDP per working person) and assess strength their impact. was conducted years 2014–2019 on basis data provided by Local Data Bank S...
