Introduction to Data Mining: Key Concepts and Applications
- Data mining involves classifying galaxies based on stages of formation and attributes such as image features and characteristics of light waves received
- The data size for this classification includes 72 million stars, 20 million galaxies, with a 9 GB object catalog and a 150 GB image database
- Regression in data mining predicts continuous valued variables based on other variables, such as sales amounts of new products or time series prediction of stock market indices
- Clustering in data mining involves finding groups of objects with similar characteristics while maximizing inter-cluster distances and minimizing intra-cluster distances
- Applications of cluster analysis include custom profiling for targeted marketing, grouping related documents for browsing, and summarization to reduce the size of large datasets
- Market segmentation and document clustering are two key applications of clustering, involving the subdivision of markets into distinct subsets of customers and grouping similar documents based on important terms
- Association rule discovery in data mining involves producing dependency rules to predict the occurrence of an item based on occurrences of other items within a set of records
- Market-basket analysis, telecommunication alarm diagnosis, and medical informatics are examples of applications for association analysis
- An example of association analysis is the identification of a subspace differential coexpression pattern enriched with the TNF/NFB signaling pathway related to lung cancer
- Deviation/anomaly/change detection in data mining is used for detecting significant deviations from normal behavior and has applications in credit card fraud detection, network intrusion detection, and monitoring forest cover changes
- The motivating challenges in data mining include scalability, high dimensionality, heterogeneous and complex data, data ownership and distribution, and non-traditional analysis
- Data in data mining consists of a collection of data objects and their attributes, where an attribute is a property or characteristic of an object, such as eye color or temperature.
