2.  Lots of collected and warehoused data being
 Computer have become cheaper and more powerful
 Competitive pressure
 Data explosion problem
 Starving for knowledge
 Solution is data mining

3.  Extraction of implicit, previously unknown and
potentially useful information from data
 Exploration and analysis by automatic or semi
automatic means of large quantity of data
to discover meaning full pattern

4.  What is data mining?
Data mining is knowledge discovery, extraction of
interesting non trivial, implicit, previously unknown
and useful information or pattern.
 what is not data mining?
 Expert system or statistical programs
 Deductive query processing

5.  Data base to be mined.
Relational, transactional, object oriented, time series,
etc..
 Knowledge to be mined
Characterization, clustering, discrimination,
association, trend etc..
 Techniques utilized
Data base oriented, data ware house(OLAP),machine
learning, statistics, neural network etc
 Applications adapted
Retail, telecommunication ,banking, fraud detection,
market analysis etc

6. prediction task
 Classification
 Regression
