Fuzzy rough approximations for set-valued data
Rough set theory is one of important tools of soft computing, and rough approximations are the essential elements in rough set models. However, the existing fuzzy rough set model for set-valued data, which is directly constructed based on a kind of similarity relation, fail to explicitly define fuzzy rough approximations. To solve this issue, in this paper, we propose two types of fuzzy rough a...
متن کاملTotally coherent set-valued probability assessments
We introduce the concept of total coherence of a set-valued probability assessment on a family of conditional events. In particular we give sufficient and necessary conditions of total coherence in the case of interval-valued probability assessments. Some relevant cases in which the set-valued probability assessment is represented by the unitary hypercube are also considered.
متن کاملL-valued Fuzzy Rough Sets
In this paper, we take a GL-quantale as the truth value table to study a new rough set model—L-valued fuzzy rough sets. The three key components of this model are: an L-fuzzy set A as the universal set, an L-valued relation of A and an L-fuzzy set of A (a fuzzy subset of fuzzy sets). Then L-valued fuzzy rough sets are completely characterized via both constructive and axiomatic approaches.
متن کاملProbability on Finite Set and Real-Valued Random Variables
One can prove the following four propositions: (1) Let X be a non empty set, S1 be a σ-field of subsets of X, M be a σ-measure on S1, f be a partial function from X to R, E be an element of S1, and a be a real number. Suppose f is integrable on M and E ⊆ dom f and M(E) < +∞ and for every element x of X such that x ∈ E holds a ≤ f(x). Then R(a) ·M(E) ≤ ∫ f E dM. (2) Let X be a non empty set, S1 ...
متن کاملRough set theory for the interval-valued fuzzy information systems
The notion of a rough set was originally proposed by Pawlak [Z. Pawlak, Rough sets, International Journal of Computer and Information Sciences 11 (5) (1982) 341–356]. Later on, Dubois and Prade [D. Dubois, H. Prade, Rough fuzzy sets and fuzzy rough sets, International Journal of General System 17 (2–3) (1990) 191–209] introduced rough fuzzy sets and fuzzy rough sets as a generalization of rough...
