Outline
  • Why IDA?
  • The definition of IDA
  • Knowledge and rules
  • Tools for IDA
  • Evaluation of IDA results
  • Reference

4
Why IDA - Interest and Excitement
  • Decision making is asking for information and
    knowledge.
  • Data processing can offer this stuff.
  • Multidimensionality of problems is looking for
    methods for adequate and deep data processing and
    analysis.

5
The definition of IDA
  • IDA is an interdisciplinary study concerned with
    the effective analysis of data
  • IDA is used for extracting useful information
    from large quantities of online data extracting
    desirable knowledge or interesting patterns from
    existing databases
  • IDA is a way of data analysis based on artificial
    intelligence, on methods enabling to find out
    information and knowledge for a particular data
    domain.

6
Also known as
7
IDA gives Knowledge
8
Knowledge is
  • The distillation of information that has been
    collected, classified, organized, integrated,
    abstracted and value-added
  • At a level of abstraction higher than the data,
    and information on which it is based and can be
    used to deduce new information and new knowledge
  • Usually in the context of human expertise used in
    solving problem.

9
Knowledge in a domain can be expressed as a
number of rules
10
Rule is
  • A formal way of specifying a recommendation,
    directive, or strategy, expressed as IF premise
    THEN conclusion or IF condition THEN action

11
How to discover rules hidden in the data?
12
Tools for IDA - See 5
  • The program for analyzing data and generating
    classifiers in the form of decision trees and or
    rule sets.
  • IF (attribute1 is less-equal-greater-then v1 and
    attributen is less-equal-greater-then vn) THEN
    (class is equal ci)  

13
Tools for IDA - Cubist
  • Analyzes data and generates rule-based piecewise
    linear models collections of rules, each with
    an associated linear expression for computing a
    target value.
  • IF (attribute1 is less-equal-greater-then v1 and
    attributen is less-equal-greater-then vn) THEN
    (class is a function-linear-regression of
    attributes)

14
Tools for IDA - ILLM
  • The tool constructs classification models in the
    form of rules which represent knowledge about
    relations hidden in data.
  • IF (attribute1 is less-equal-greater-then v1 and
    attributen is less-equal-greater-then vn) THEN
    (class is equal ci)

15
Tools for IDA - Magnum Opus
  • Finds association rules providing competitive
    advantage by revealing underlying interactions
    between factors within the data.
  • IF (attributei is less-equal-greater-then vi and
    attributen is  less-equal-greater-then vn) THEN
    (attributej is less-equal-greater-then vj )
  • or
  • IF (itemi itemk itemn) THEN itemj

16
Evaluation of IDA results
  • Absolute relative accuracy
  • Sensitivity specificity
  • False positive false negative
  • Error rate
  • Reliability of rules
  • Etc
