(odm ( organization data mining به عنوان ابزار استخراج دانش اتکاپذیری ازداده ها تعریف شده است و فن آوری است که فرایند تصمیم گیری رابوسیله ی دگرگون ساختن داده ها به سوی دانش ارزشمند درجهت کسب یک مزیت رقابتی سوق می دهد و بعنوان شیوه بکاربردن ابزارهای داده کاوی تعریف شده است . با توجه به اینکه سازمان ها ، داده های تجاری بسیاری رادر تصرف خوددارند بافلج ساختن اطلاعات یک چالش کلیدی درتصمیم گیری تشکیل...
요 약 Intelligent and adaptive services for mobile users are researchable topics nowadays to be able to provide the mobile user an immediate knowledge of the location. This research work presents a framework for collaborative location-based services and uses data mining approach based on neuro-fuzzy system. The proposed framework supports data mining for knowledge discovery to location informatio...
This paper describes a prototype intelligent intrusion detection system (IIDS) that is being developed to demonstrate the effectiveness of data mining techniques that utilize fuzzy logic. This system combines two distinct intrusion detection approaches: 1) anomaly based intrusion detection using fuzzy data mining techniques, and 2) misuse detection using traditional rule-based expert system tec...
Wireless sensor networks are usually deployed for monitoring given physical phenomena taking place in a specific space and over a specific duration of time. The spatio-temporal distribution of these phenomena often correlates to certain physical events. To appropriately characterise these events-phenomena relationships over a given space for a given time frame, we require continuous monitoring ...
Data mining, also known as knowledge discovery in databases, is the process of discovery potentially useful, hidden knowledge or relations among data from large databases. An important topic in data mining research is concerned with the discovery of association rules. The majority of databases are distributed nowadays. In this paper is presented an algorithm for mining fuzzy association rules f...
Evaluation of the nutritional effects of fasting on cardiovascular diseases, using fuzzy data mining
Background: Advances in information technology and data collection methods have enabled high-speed collection and storage of huge amounts of data. Data mining can be used to derive laws from large data volumes and their characteristics. Similarly, fuzzy logic by facilitating the understanding of events is considered a suitable complement to scientific data mining. Materials and Methods: The pre...
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...
The research area of Data Mining or Knowledge Discovery in Databases has emerged in response to the challenges of analyzing the tremendously growing datasets gathered nowadays by companies and research institutions. Classification is one important task of data mining, where fuzzy techniques to extract classification rules from data are appealing due to their human understandable modeling. Often...
Copyright © 2009, IGI Global, distributing in print or electronic forms without written permission of IGI Global is prohibited. In this chapter we discuss how fuzzy logic extends the envelop of the main data mining tasks: clustering, classification, regression and association rules. We begin by presenting a formulation of the data mining using fuzzy logic attributes. Then, for each task, we pro...
Effective methods for feature and model structure selection are very important for data-driven modeling, data mining, and system identification tasks. This paper presents a new method for selecting important variables (regressors) in nonlinear (dynamic) models with mixed discrete (categorical, fuzzy) and continuous inputs and outputs. The proposed method applies fuzzy association rule mining. T...
