Cheating: Cheating will not be tolerated. All work you submitted must be entirely your own. Any suspicious similarities between students' work will be recorded and brought to the attention of the Dean. The MINIMUM penalty for any student found cheating will be to receive a 0 for the item in question, and dropping your final course grade one letter. The MAXIMUM penalty will be expulsion from the University. Late assignments: Late assignments will not, in general, be accepted. They will never be accepted if the student has not made special arrangements with me at least one day before the assignment is due. If a late assignment is accepted it is subject to a reduction in score as a late penalty.CS 583 11Introduction to Data MiningCS 583 12What is data mining?Data mining is also called knowledge discovery and data mining (KDD)Data mining isextraction of useful patterns from data sources, e.g., databases, texts, web, image. Patterns must be:valid, novel, potentially useful, understandableCS 583 13Example of discovered patternsAssociation rules:“80% of customers who buy cheese and milk also buy bread, and 5% of customers buy all of them together”Cheese, Milk Bread [sup =5%, confid=80%]CS 583 14Main data mining tasksClassification:mining patterns that can classify future data into known classes. Association rule miningmining any rule of the form X Y, where X and Y are sets of data items. Clusteringidentifying a set of similarity groups in the dataCS 583 15Main data mining tasks (cont …)Sequential pattern mining:A sequential rule: A B, says that event A will be immediately followed by event B with a certain confidenceDeviation detection: discovering the most significant changes in dataData visualization: using graphical methods to show patterns in data.CS 583 16Why is data mining important?Rapid computerization of businesses produce huge amount of dataHow to make best use of data?A growing realization: knowledge discovered from data can be used for competitive advantage.CS 583 17Why is data mining necessary?Make use of your data assetsThere is a big gap from stored data to knowledge; and the transition won’t occur automatically.Many interesting things you want to find cannot be found using database queries“find me people likely to buy my products”“Who are likely to respond to my promotion”CS 583 18Why data mining now?The data is abundant.The data is being warehoused.The computing power is affordable.The competitive pressure is strong.Data mining tools have become availableCS 583 19Related fieldsData mining is an emerging multi-disciplinary field:StatisticsMachine learningDatabasesInformation retrievalVisualizationetc.CS 583 20Data mining (KDD) processUnderstand the application domainIdentify data sources and select target dataPre-process: cleaning, attribute selectionData mining to extract patterns or modelsPost-process: identifying interesting or useful patternsIncorporate patterns in real world tasksCS 583 21Data mining applicationsMarketing,
