Association rules have been used for obtaining information hidden in a database. Recent researches have pointed out that simple associations are insu cient for representing the diverse kinds of knowledge collected in ...

Nowadays, the annotation of videos with high-level semantic concepts or features is a great challenge. In this paper, this problem is tackled by learning, by means of Fuzzy Decision Trees (FDT), automatic rules based on ...

We propose a general semantic notion of modal many-valued logic. Then, we explore the di culties to characterize this notion in a syntactic way and analyze the existing literature with respect to this framework

We prove an in nitary version of the Double Recursion Theorem of Smullyan. We give some applications which show how this form of the Recursion Theo- rem can be naturally applied to obtain interesting in nite sequences ...

Explicit inclusion of logic in the process of aggregation (information fu- sion) is very important in real problems from many points of view such as adequacy and transparency. In this paper aggregation is treated as a ...

This paper deals with the relationship between bounded pseudo-distances and its associated W'-indistinguishabilities, from which the idea of threshold of transitivity comes. By the way, bounded pseudo-distances are characterized

The aim of this paper is to present a general framework for comparing fuzzy sets with respect to a general class of fuzzy orderings. This approach includes known techniques based on generalizing the crisp linear ordering ...

Upper probability measures are measures of uncertainty that generalize probability measures in order to deal with non-measurable events. Following an approach that goes back to previous works by H ajek, Esteva, and ...

We consider a pair of exchangeable lifetimes X; Y and the families of the conditional survival functions F t(x;y) of (X t; Y t) given (X > t; Y > t).We analyze some properties of dependence and of ageing for F t(x;y) ...
