Statement of the Problem

An Evaluation of Commercial Data Mining Capabilities, for example Oracle9i’s Data Mining Suite.

Background

Data mining is a relatively new offshoot ofdatabase technology which has arisen as a resultof the ability of computers to: Store vast quantities of data in data warehouses. Implement ingenious algorithms for the mining

of data. Use these algorithms to analyse these vast

quantities of data in a reasonable amount of time.

Data mining discovers the patterns in data that represent knowledge.

It is of interest what algorithms data mining suites use and how well each category of data mining algorithm performs on data and what kind of results are produced.

Another important issue is usability of the algorithm.

Data A and B random numbers generated in Excel.

Data c = 2*(data a) + 3*(data b).

51st value calculated by Excel:4.37385831

Value calculated using Knowledge Miner – a Macintosh data mining tool:

4.34791231 and the equation :

1.97*(data a) + 2.96*(data b) + 0.0324

Experiment repeated using three columns of random numbers and this equation:

Data d = 23*(data a)-4.5*(data b)+(data a + data c) .

The last five entries for Data D were missing from the column.

These were generated by Excel:14.7314558 12.0720505 22.0008992 7.52633344 5.25167700 These are what Knowledge Miner predicted:14.7341613 12.0731391 22.0080223 7.52465867 5.24861860

Plan of Action

Literature Survey (and other resources) Install Software for Oracle Get to know the Oracle Suite Evaluate Oracle9i’s Data Mining Suite

Install Software for Oracle

Including JDeveloper May be extended to the installation of

other commercial data mining suites eg.

DB2’s Intelligent Miner

Informix’s Data Mine

Investigate Oracle9i’s Data Mining Suite Two major algorithm types – supervised and

unsupervised learning. A Medical Example:

Supervised learning – researchers input medical profiles into a leukaemia model to predict propensity for the disease.Unsupervised learning – searches for clusters of related information in data sets to reveal insights about diseases and patient populations.

Get to know the Oracle DM Suite (a major task). Explore JDeveloper, Oracle9i’s Java

based API. JDeveloper complies with JDM (Java Data

Mining) used by Oracle, Sun, IBM and others.

Explore DM4J( Data Mining for Java) the new Graphical User Interface for Oracle DM.

Addressing the Problem:

Run the different algorithms available in the data mining suite.

Document and analyse results in terms of performance and effectiveness of algorithm.

Expected Results:

The ability to say conclusively whether Oracle's data mining capabilities are inferior or superior to anything else in the market place and why this can be stated.

Possible Extensions to the Project: To have sufficient knowledge of the topic to give

recommendations or feedback: to Oracle regarding their data mining suite. to IT customers wanting to purchase data mining

suites. Explore the field of Random stereograms- could

a computer see them? If not, why not?
