Data mining and its applications!

  1. 1. Costarch Analytical Consulting Pvt Ltd.
  2. 2. Data Mining  Why data mining  What is data mining  Scope of data mining  Typical applications  Issues with data mining
  3. 3. What it is?
  4. 4. Data Mining Contd…..  A data mining research carried out at supermarkets showed that,  Men who had children and who do shopping on Saturday to buy nappies for their little ones tend to buy Beer also….  Interesting right?.....  Lets see some more examples……
  5. 5. Data Mining Contd..  helps in churn prevention.
  6. 6. Data mining Contd.. o Data mining in CRM o Based on the behavior and personal data about the customer, CRM admisnitrter will divide the customer in two classes. o A Prediction model can be created using this data to find the probability of losing a customer in next two years.
  7. 7. Data Mining Contd..  IN CRM , it is a well known fact that acquiring a new customer cost 7 times more than keeping the existing customer (churn prevention)  Thus CRM can help to reduce the churn rate
  8. 8. Why Data Mining is important ? Data
  9. 9. Why Data Mining is important?
  10. 10. Why Data Mining  Terabytes of data generated every day  Abundance of data available from sources like business, society and science  Easy techniques of data collection ex: automated data collection tools, database systems, computerized society etc  Need for analysis of massive data
  11. 11. What is Data Mining It is a process of discovering  suitable  New  Potentially useful insights  Under stable patterns and trends in the large data sets  Using sophisticated mathematical algorithms  To segment the data  Evaluate the probability for future events
  12. 12. Stages of Data mining Selection •Segmenting the data according to criteria •Example who have a car, people who are in govt jobs Preprocessing •Data cleansing stage, unnecessary information is removed Transformation . Data is transformed. Data is made usable and navigable Data mining . Stage of extracting of patterns from data Interpretation and evaluation •Patterns interpreted into knowledge that can be used to support human decision making,
  13. 13. Reasons for Data Mining popularity  Growing Data Volume  Limitations of Human Analysis  Low Cost of Machine Learning
  14. 14. Data Mining Models  Verification Model  Discovery Model
  15. 15. Data Mining Process Model Understanding business requirements Deployment Data collection Data Data prep and analysis Evaluation Data modeling
  16. 16. Scope of Data Mining  Data Mining technology can generate new business opportunities  Automated prediction of trends and behaviors  Automated discovery of previously unknown patterns  Yield the benefits of automation on existing software and hardware platforms  Implemented on new systems as existing platforms are upgraded and new products developed
  17. 17. Data Mining Limitations  Data mining systems relies on databases to supply the raw data for output.  Problem occurs as data bases tend to be dynamic, incomplete, noisy and large  Uncertainty  Size and updating problem  Limited information
  18. 18. Techniques used in Data Mining  Artificial Neural Networks  Decisions Trees  Genetic Algorithm  Nearest Neighbor Method  Rule Induction
  19. 19. Artificial Neural Networks o System of interconnected neurons that can compute values from inputs by feeding information through the network.
  20. 20. Decision Tree  Uses tree like model of decisions and their possible consequences
  21. 21. Genetic Algorithm o Generate useful solutions to optimization and search problems.
  22. 22. Nearest Neighbor Method  Classifying cases based on their similarity to other cases
  23. 23. Rule induction  The extraction of useful if-then rules from data based on statistical significance.
  24. 24. Data Mining Application Data mining techniques can be applied in various fields such as  Telecommunication  CRM  Banking  Medicine and Pharmaceuticals  Insurance  Management (Quality Assurance, Marketing)  Travel and Tourism..
  25. 25. Contd..  Media logistic  Academic Research  IT & ITES  Online Portals and Social Media Channels  Media and Advertising  Airline Companies  Sports  Finance  Film Industry and many more etc.
