A Data Imputation Method with Support Vector Machines for Activity-Based Transportation Models
In this paper, a data imputation method with a Support Vector Machine (SVM) is proposed to solve the issue of missing data in activity-based diaries. Here two SVM models are established to predict the missing ...

Learning Method Inspired on Swarm Intelligence for Fuzzy Cognitive Maps: Travel Behaviour Modelling
Although the individuals’ transport behavioural modelling is a complex task, it has a notable social and economic impact. Thus, in this paper Fuzzy Cognitive Maps are explored to represent the behaviour and op...

Rough Sets Based Incremental Rule Acquisition in Set-Valued Information Systems
Set-valued information systems may evolve over time. How to acquire rules from updating information systems is vital in decision making. Rule acquisition from set-valued decision information systems needs both...

Using Belief Degree Distributed Fuzzy Cognitive Maps for Energy Policy Evaluation
Cognitive maps (CMs) were initially for graphical representation of uncertain causal reasoning. Later Kosko suggested Fuzzy Cognitive Maps (FCMs) in which users freely express their opinions in l...

Implications in Fuzzy Logic: Properties and a New Class
An implication in fuzzy logic, commonly defined as a two-place operation on the unit interval, is an extension of the classical binary implication. It plays important roles in both mathematical and applied sid...

An optimal model of information diffusion principles to risk and decision analysis of breast cancer morbidity
Information diffusion methods (IDMs) often deal with “small sample problems” and distribute the information of one data point to its neighbors in fuzzy information processing. By considering new criteria, we e...

Open AccessComputing with Words in Decision support Systems: An overview on Models and Applications
Decision making is inherent to mankind, as human beings daily face situations in which they should choose among different alternatives by means of reasoning and mental processes. Many of these decision problem...

α-Satisfiability and α-Lock Resolution for a Lattice-Valued Logic LP(X)
This paper focuses on some automated reasoning issues for a kind of lattice-valued logic LP(X) based on lattice-valued algebra. Firstly some extended strategies from classical logic to LP(X) are investigated in o...

On Compactness and Consistency in Finite Lattice-Valued Propositional Logic
In this paper, we investigate the semantical theory of finite lattice-valued propositional logic based on finite lattice implication algebras. Based on the fuzzy set theory on a set of formulas, some propositi...

On a New Class of Implications in Fuzzy Logic
We define and study a new class of implications determined only by a negation. We examine under which conditions the most popular eight axioms for implications are satisfied. We obtain the intersection of the ...
