Study Notes
Introduction to Data Mining
- The class model is based on features like success stories, early class stages of formation, intermediate and late data sizes, object catalog, and image database.
- Regression is used to predict continuous valued variables based on other variables, with examples like predicting sales amounts and time series prediction of stock market indices.
- Clustering involves finding groups of similar objects, with applications in custom profiling for targeted marketing, grouping related documents for browsing, and reducing the size of large data sets.
- Market segmentation and document clustering are applications of clustering, aimed at subdividing markets and finding groups of similar documents, respectively.
- Association rule discovery involves producing dependency rules to predict the occurrence of an item based on occurrences of other items, with applications in market-basket analysis, telecommunication alarm diagnosis, and medical informatics.
- An example of association analysis is the subspace differential coexpression pattern, enriched with the TNF/NFB signaling pathway, related to lung cancer.
- Deviation/anomaly/change detection is used to detect significant deviations from normal behavior, with applications in credit card fraud detection, network intrusion detection, and identifying abnormal behavior from sensor networks.
- The motivating challenges in data mining include scalability, high dimensionality, heterogeneous and complex data, data ownership and distribution, and non-traditional analysis.
