DM: New rule induction system

[Alexandr A. Savinov]

Hi,

New original rule induction system is now available for evaluation. 
It works under Windows'95 and requires DAO 3.5 (available in 
MS Office 97). Although it is a prototype version it allows to 
run the algorithm and view the result. You can download this system 
from my home page:

(section Download Software). Some instructions can be found in 
ReadMe.doc file.

The algorithm is based on the notion of prime disjunction and 
transformation from DNF to CNF. The problem has been formulated 
and solved for fuzzy case but the current version is crisp. Some 
information can be found in my recent paper "Application of 
Multi-dimensional Fuzzy Analysis to Decision Making" which can 
be found on my home page (HTML and PS). More general information 
is also available in other online papers.

One feature of the approach is that it proceeds from negative 
iformation in the database, i.e., it takes into account what 
has not happened, what records are absent (negative associations), 
while conventional methods (e.g., apriori) take into account 
positive information, i.e., what happened, what is present in the 
database. This reflects the duality between (fuzzy) CNF and DNF.

Thanks.

Regards,

Alexandr
