  1. An overview of The IBM Intelligent Miner for Data By: Neeraja Rudrabhatla 11/04/1999

  2. Mining Features supported by the Data Miner: • Association Rules • Clustering - Demographic, Neural networks • Predicting classifications - Neural Networks, Decision Trees • Predicting values • Discovering sequential patterns • Discovering similar time sequences

  3. Steps for mining data using the Data Miner: • Creation of data • Analyze and prepare data for mining • Mine the data using one or a combination of mining techniques • Visualize mining results using advanced graphical techniques

  4. Main Window of the Data Miner:

  5.

  23. Results of PlayTennis: In-sample: 2 Out-sample: 1

  24. One partition of the PlayTennis-Prediction:

  25. Textual Representation of a single partition:

  26. Sequential Patterns Mining and Time Sequence Mining: • Sequential patterns are used to find predictable patterns of behavior over a period of time. (A certain behavior at a given time is likely to produce another behavior or a sequence of behaviors within a certain time-span) • Time sequences help find all occurrences of similar subsequences in a database of time sequences.

  27. Sequences: • Combine several objects into a single object that you can run • The benefit is that you can combine several steps into one step • If you combine several functions into a sequence, you need run only the sequence, which then runs each of the objects within it

  28. Applications: The Intelligent Miner offerings are intended for use by Data Analysts and Business Technologists in the following areas: • Perform database marketing • Streamline business and manufacturing processes • Detect potential cases of fraud • Helps in customer relationship management
