An Alternative Estimation of Market Volatility based on Fuzzy Transform

, 2017
Realization of uncertainty of prices is captured by volatility, that is the tendency of prices to vary along a period of time. This is generally measured as standard deviation of daily returns.

Using the Choquet Integral in the Fuzzy Reasoning Method of Fuzzy Rule-Based Classification Systems

Axioms, 2013
In this paper we present a new fuzzy reasoning method in which the Choquet integral is used as aggregation function. In this manner, we can take into account the interaction among the rules of the system.

A New Interval-Valued Fuzzy Set Knowledge and Accuracy Measure with Applications in Multi-Criteria Decision-Making and Recognizing Patterns

Fuzzy Information and Engineering
Fuzzy sets with interval values are a generalization of conventional fuzzy sets. The theoretical understanding of interval-valued fuzzy sets rests under the presumption that each element possesses a single real-valued truth membership degree that falls ...

Fuzzy image segmentation using location and intensity information [PDF]

, 2003
The segmentation results of any clustering algorithm are very sensitive to the features used in the similarity measure and the object types, which reduce the generalization capability of the algorithm.

Measuring finite Quantum Geometries via Quasi-Coherent States

, 2016
We develop a systematic approach to determine and measure numerically the geometry of generic quantum or "fuzzy" geometries realized by a set of finite-dimensional hermitian matrices.

Matrix Representation of Capacity-Based Multicriteria Decision Analysis

IEEE Access, 2019
Matrix algebra is an efficient way to represent the relationship between different concepts in the multiple criteria decision analysis theory. The main purpose of this paper is to provide a compact and systematic representation of the capacities and ...

Some Result on Fuzzy Integration

Transactions on Fuzzy Sets and Systems
‎In this article‎, ‎we introduce a new concept of fuzzy measurement‎, ‎the space of fuzzy measurable functions and fuzzy integral‎, ‎which has a dynamic position and is different from previous approaches‎. ‎With this concept‎, ‎we create a new version of

Metric on the space of systems behavior functions represented by fuzzy measures [PDF]

Yugoslav Journal of Operations Research
G. Klir proposed to describe the behavior of complex systems using behavior functions (BFs) - invariant constraints on the set of system states. BFs are one of the most productive tools for studying the functioning of systems.
