Unsupervised Data Mining in Nominally-Supported Databases
نویسنده
چکیده
The meaning of structure or pattern for data which ful lls only nominal requirements will be investigated. Basic Informationand Uncertainty-measures will be discussed and a theoretical framework of four basic techniques for structurending introduced. I will conclude with an overview of a set of both, well known and less known methods, which will be related to each other, to the structurending problem and also to the introduced basic techniques. To contrast the nominal-data, unsupervised approach some fundamental methods of the much more investigated continuous, supervised domain will also

Grid Density Clustering Algorithm
Data mining is the method of finding the useful information in huge data repositories. Clustering is the significant task of the data mining. It is an unsupervised learning task. Similar data items are grouped together to form clusters. These days the clustering plays a major role in every day-to-day application. In this paper, the field of KDD i.e. Knowledge Discovery in Databases, Data mining...
متن کاملFrom unsupervised learning to data mining: linking cognition and data analysis
Recently, Knowledge Discovery on Databases (KDD) has emerged as a promising research area encompassing methods from several disciplines. Particularly, the data mining step of KDD shares most of its goals with unsupervised learning. But data mining methods are biased towards statistical techniques arguing that Machine Learning (ML) methods are not suitable to deal with real-world databases. We c...
متن کاملAnalysis of Diverse Clustering Tools in Data Mining
Clustering in data mining is an unsupervised learning technique of aggregating the data objects into meaningful groups such that the intra cluster similarity of objects are maximized and inter cluster similarity of objects are minimized. Over the past decades several clustering tools were emerged in which clustering algorithms are inbuilt and are easier to use and extract the expected results. ...
متن کاملMetapattern Generation for Integrated Data Mining
Metapatterns (also known as metaqueries) have been proposed as a new approach to integrated data mining, and applied to several real-world applications successfully. However, designing the right metapatterns for a given application still remains a diiculty task. In this paper, we present a metapattern generator that can automatically generate metapatterns from new databases. By integrating this...
متن کاملMining Concept Drift from Data Streams by Unsupervised Learning
Mining is involved with knowing the unknown characteristics from the databases or gaining of Knowledge (Knowledge Discovery) from Databases to get more useful information from the database. Real time databases which are constantly changing with time, there may arise a point when traditional Data Mining techniques may not be adequate as there may be a previously unknown class label involved or n...
