Data Mining in a Nut Shell Essay example -- Essays Papers

selective information Mining in a orchis ShellIn todays business world, information virtually the customer is a necessity for a businesses trying to maximize its profits. A new, and important, tool in gaining this knowledge is Data Mining. Data Mining is a settle of automated procedures used to find previously unknown patterns and relationships in info. These patterns and relationships, once extracted, butt be used to make valid predictions approximately the behavior of the customer.Data Mining is generally used for four briny tasks (1) to improve the process of making new customers and retaining customers (2) to reduce fraud (3) to secernate internal wastefulness and deal with that wastefulness in operations, and (4) to chart undiscovered atomic number 18as of the internet (Cavoukian). The fulfillment of these tasks can be enhanced if appropriate data has been collected and if that data is stored in a data w arhouse. According to Stanford University, A Data W atomic n umber 18house is a repository of integrated information, available for queries and analysis. Data and information are extracted from heterogeneous sources as they are generated....This makes it much easier and much efficient to run queries over data that originally came from different sources. When data about an organizations practices is easier to access, it becomes more economical to mine. Without the pool of formalize and scrubbed data that a data warehouse provides, the data tap process requires considerable additional effort to pre-process the data (SAS Institute).There are several different types of models and algorithms used to mine the data. These include, but are non limited to, neural networks, decision trees, rule origination, boosting, and genetic algorithms. flighty networks are physical cellular systems which can acquire, store, and utilize experiential knowledge (Zurada). Neural networks offer a way to efficiently model large and daedal problems. D ecision trees are diagrams used for making decisions in business or computer programming. Branches are used to represent choices with associated risks, costs, results, or probabilities. Rule induction is a way of deriving a set of rules to classify cases (Two Crows). These set of rules differ from those in a decision tree in that they are independent from one another. Boosting is a technique in which multiple ergodic samples of data are taken and a... ...networks, fuzzy logic and genetic algorithms.http//www.partek.com/. MITWINROSAWINROSA is a software tool which generates automatically Fuzzy If-Then Rules from your data. The generated data set can be run by most of the existing fuzzy tools ilk e.g. DataEngine, fuzzyTECH, and Matlab.http//www.mitgmbh.de/Attar SoftwareXpertRuleData Mining using high consummation parallel SQL technologyA Windows PC client being able to intelligently head the data source on the host server can action knowledge Induction. The speed of the pr ocess is therefore dependant upon the server - not the speed of the client PC. This allows data mining to exploit the speed offered by MPP servers (Massive Parallel Processors) and database architectures that are optimized for serving queries.http//www.attar.com/Works CitedCavoukian, Ann, Ph.D. Data Mining Staking a Claim on Your Privacy.
