Classification Of Data Mining Techniques - 1512 Words

Abstract Data mining is the process of extracting hidden information from the large data set. Data mining techniques makes easier to predict hidden patterns from the data. The most popular data mining techniques are classification, clustering, regression, association rules, time series analysis and summarization. Classification is a data mining task, examines the features of a newly presented object and assigning it to one of a predefined set of classes. In this research work data mining classification techniques are applied to disaster data set which helps to categorize the disaster data based on the type of disaster occurred in worldwide for past 10 decade. The experimental comparison has been conducted among Bayes classification algorithms (BayesNet and NaiveBayes) and Rules Classification algorithms (DecisionTable and JRip). The efficiency of these algorithms is measured by using the performance factors; classification accuracy, error rate and execution time. This work is carried out in t he WEKA data mining tool. From the experimental result, it is observed that Rules classification algorithm, JRip has produced good classification accuracy compared to Bayes classification algorithms. By comparing the execution time the NaiveBayes classification algorithm required minimum time. Keywords: Disasters, Classification, BayesNet, NaiveBayes, DecisionTable, JRip.

Further the classification is used to forecast group relationship for precise data instance. It is generally construct models that are used to predict potential statistics trends. The major objective of machine data is to perfectly predict the class for each record. This article focuses on a survey onRead MoreData Analysis : Data Mining1567 Words   |  7 PagesIntroduction Data, Data everywhere. It is a precious thing that will last longer than the systems.

To obtain accurate rainfall prediction the above said factors should be well maintained and controlled. For this purpose a number of methods have been proposed. Fuzzy inference is used for mapping I/P and O/P sets with a set of fuzzy rules. Fuzzy inference is performedRead MoreData Mining And Knowledge Discovery1661 Words   |  7 PagesData miming Data mining or Knowledge Discovery in Databases (KDD) is discovering patterns from large data groups through methods of artificial intelligence, machine learning ,statistics, and database systems. The aim of data mining process is to extract information from a data group and switch it to an ideal format for future . The data mining process comprise of database and data management aspects, data preprocessing, inference, complexity of discovered structures, and updating. The Data miningRead MoreA Research Study On Data Mining1171 Words   |  5 PagesData mining is the process of discovering patterns, trends, correlations from large amounts of data stored electronically in repositories, using statistical methods, mathematical formulas, and pattern recognition technologies (Sharma n.d.). The main idea is to analyze data from different perspectives and discover useful trends, patterns and associations. As discussed in the previous chapter, the healthcare organizations are producing massive amounts of electronic medical records, which are impossibleRead MoreClassification And Novel Class Detection Approaches Of Feature Evolving Data Stream1716 Words   |  7 PagesA Survey On Various Classification And Novel Class Detection Approaches Of Feature Evolving Data Stream Abstract: The classification of data stream is challenging task for data mining community. Dynamic changing nature of data stream has some difficulties such as feature evolution, concept evolution, concept drift and infinite length. As we know that the data streams are huge in amount, it is impractical to store and use all the data for training. Concept drift occurs when underlying concept changesRead MoreA Study On Semi Automatic Dm Technique For Discovering Meaningful Relationships From A Given Data Set Essay1693 Words   |  7 PagesIntroduction The term DM was conceptualised as early as 1990s as a means of addressing the problem of analysing the vast repositories of data that are available to mankind, and being added to continuously. DM has been the oldest yet one of the interesting buzzwords. It involves defining associations, or patterns, or frequent item sets, through the analysis of a given data set. Further-more, the discovered knowledge should be valid, novel, useful, and understandable to the user.

The merging of technology with the management of customer relationship will result in an improved overall process. The technique of data mining will not only solve the issue but also the policies and the strategies so designed could be more effective and competent. Thus the money spent on the customer retention programs/schemes can be saved by being more direct and specific. SCOPE In the present growingRead MoreNotes On Web Usage Mining1615 Words   |  7 Pages2. WEB USAGE MINING Data mining techniques can be mainly divided into three categories: Web structural mining, Web Content mining and web usage mining. Web structural mining is used to discover structure from data available on web like hyperlinks and documents. It can be helpful to the user for navigating within documents as mining can be done to retrieve intra and inter hyperlinks and DOM structure out of documents. Web Content mining can be used to extract information from the data available on
