Special Issue Information

Dear Colleagues, 

In the era of the Internet of Things and big data, the use of advanced computational intelligence approaches for the extraction of knowledge has emerged and become a process that is now required to conduct decision analyses in various application fields.

In general, the nature of the information and the reasoning processes applied to it are blurred and must be treated with the use of fuzzy-based data mining and approximate reasoning methods and techniques as applied to an increasing knowledge base and on complex models representing the real world.

This Special Issue is aimed at researchers and scholars who wish to propose fuzzy computational intelligence methods and models of knowledge extraction and approximate reasoning for application to massive and multidimensional data.

We hope this Special Issue will attract numerous researchers who will help in providing an update on the latest developments in the field of fuzzy-based computational intelligence techniques in the presence of massive data and their important applications in complex real-world problems.

Some topics that the contributions may focus on include:

  • fuzzy models in time series analysis;
  • fuzzy clustering models and fuzzy approaches to classify massive and multidimensional data;
  • fuzzy multiobjective optimization methods in data analysis;
  • hybrid approaches of fuzzy machine learning and fuzzy deep learning;
  • type-2 fuzzy rule-based systems;
  • fuzzy massive data fusion techniques;
  • fuzzy decision making.

Cluster-based hot spot detection is applied in many disciplines to analyze the locations, concentrations, and evolution over time for a phenomenon occurring in an area of study. The hot spots consist of areas within which the phenomenon is most present; by detecting and monitoring the presence of hot spots in different time steps, it is possible to study their evolution over time. One of the most prominent problems in hot spot analysis occurs when measuring the intensity of a phenomenon in terms of the presence and impact on an area of study and evaluating its evolution over time. In this research, we propose a hot spot analysis method based on a fuzzy cluster hot spot detection algorithm, which allows us to measure the incidence of hot spots in the area of study. We analyze its variation over time, and in order to evaluate its reliability we use a well-known fuzzy entropy measure that was recently applied to measure the reliability of hot spots by executing fuzzy clustering algorithms. We apply this method in crime analysis of the urban area of the City of London, using a dataset of criminal events that have occurred since 2011, published by the City of London Police. The obtained results show a decrease in the frequency of all types of criminal events over the entire area of study in recent years. Full article

Fuzzy transform is a technique applied to approximate a function of one or more variables applied by researchers in various image and data analysis. In this work we present a summary of a fuzzy transform method proposed in recent years in different data mining disciplines, such as the detection of relationships between features and the extraction of association rules, time series analysis, data classification. After having given the definition of the concept of Fuzzy Transform in one or more dimensions in which the constraint of sufficient data density with respect to fuzzy partitions is also explored, the data analysis approaches recently proposed in the literature based on the use of the Fuzzy Transform are analyzed. In particular, the strategies adopted in these approaches for managing the constraint of sufficient data density and the performance results obtained, compared with those measured by adopting other methods in the literature, are explored. The last section is dedicated to final considerations and future scenarios for using the Fuzzy Transform for the analysis of massive and high-dimensional data. Full article
