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 ...

Using Belief Degree-Distributed Fuzzy Cognitive Maps for Safety Culture Assessment
Safety Culture describes how safety issues are managed within an enterprise. In this paper we describe a prototype for safety culture assessment using Belief Degree Fuzzy Cognitive Maps. Our appr...

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...

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...

A Hybrid Approach for Fault Tree Analysis Combining Probabilistic Method with Fuzzy Numbers
Conventional fault tree analysis in safety analysis of complex engineering systems calculates the occurrence probability of the top undesired event using probabilistic failure rates. However, it is often very ...

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 ...

On a Mathematical Relationship Between the Fixed Point and the Closed Itemset in Association Rule Mining
Association rule mining is one of important research topics in knowledge discovery and data mining. Recent promising direction of association rule mining is mainly to mine closed itemsets. Based on the Galois ...
