Data Mining Methods and Applications

Data mining activities can lead to unexpected results, requiring creative decision-making.
Prediction methods use variables to predict future values, while descriptive methods find human-interpretable patterns.
Data mining tasks fall into four categories: classification, clustering, association rule discovery, and sequential pattern discovery.
Classification, a supervised induction method, is commonly used for analyzing historical data and predicting future behavior.
Data clustering algorithms partition a database into segments with similar qualities, aiming to create groups with maximum similarity and minimum similarity across groups.
The major difference between cluster analysis and classification is that classification sorts cases into groups, while cluster analysis identifies common characteristics shared by group members.
Association data mining establishes relationships between items that occur together, often used in market basket analysis.
Sequence discovery identifies associations over time, tracking elapsed time between events and frequency of occurrences.
Two types of data mining are hypothesis-driven, starting with a proposition, and discovery-driven, uncovering unknown facts.
Data mining is used in various business sectors including banking, retailing, manufacturing, marketing, government, health, airlines, and broadcasting.
Understanding customer behavior in retail involves analyzing demographic data, transaction data, and online interaction data.
In retail, data mining focuses on web analytics, gathering web statistics to track customer behavior and adjust websites to meet customer needs.
