Gradual emerging patterns (GEPs) are gradual item sets that occur less frequently in one data set and more another. For instance, let ‘fan speed’ ‘temperature’ be attributes of two numerical sets. A “the higher the speed, lower temperature” (which correlates a set’s attributes) becomes GEP if it is frequent (in terms support as pattern mining) However, such do not indicate how time gap impacts ...

The concept of intelligently controlling the search process of gravitational search algorithm (GSA) is introduced to develop a novel data mining technique. The proposed method is called fuzzy GSA miner (FGSA-miner). At first a fuzzy controller is designed for adaptively controlling the gravitational coefficient and the number of effective objects, as two important parameters which play major ro...

Fuzzy association rule mining discovers patterns in transactions, such as shopping baskets in a supermarket, or Web page accesses by a visitor to a Web site. Temporal patterns can be present in fuzzy association rules because the underlying process generating the data can be dynamic. However, existing solutions may not discover all interesting patterns because of a previously unrecognised probl...

Although data mining is relative young technique, it has been used in a wide range of problem domains over the past few decades. In this paper, the authors present a new model to forecast the cultivated land demand adopts the technique of data mining. The new model which is called fuzzy Markov Chain model with weights ameliorate the traditional Time Homogeneous Finite Markov chain model to pred...

Fuzzy systems have good modeling capabilities in several data science scenarios and can provide human-explainable intelligence models with explainability interpretability. To obtain a model for decision making, this article, we investigate explainable fuzzy-theoretic utility mining on multisequences. Meanwhile, more normative formulation of the problem fuzzy sequences is formulated. By explorin...

We propose a type-2 based clustering algorithm to capture data points and attributes relationship embedded in fuzzy subspaces. It is a modification of Gustafson Kessel clustering algorithm through deployment of type-2 fuzzy sets for high dimensional data. The experimental results have shown that type-2 projected GK algorithm perform considerably better than the comparative techniques. General T...

Due to the nature of the geological and mining activities, different input parameters in the grade estimation and mineral resource evaluation are always tainted with uncertainties. It is possible to investigate the uncertainties related to the measurements and parameters of the variogram model using the fuzzy kriging method instead of the kriging method. The fuzzy kriging theory has already bee...

This paper shows a summarization method. We focus on the construction of fuzzy prototypes by means of typical values. For this purpose, we use a formal framework of measures of comparison of values of attributes of data for the management of fuzzy databases especially for data mining. One of the originalities of this paper lies in the fact that values are fuzzy.

With the rapid expansion of computer networks during the past few years, security has become a crucial issue for modern computer systems. A good way to detect illegitimate use is through monitoring unusual user activity. The solution is an Intrusion Detection System (IDS) which is used to identify attacks and to react by generating an alert or blocking the unwanted data. For IDS, use of genetic...
