## ILLM Applications and Results

ILLM (Inductive Learning by Logic Minimization) is a set of codes designed to solve classification problems. Online rule induction system available through DMS is based on the algorithms from ILLM system. To illustrate the power of the actual ILLM methodology we have listed some real-world like data mining problems on which this methods were succesfully tested.

### KDD (Knowledge Discovery in Databases) Cup 1999

**Description**

Detailed description of the problem and results can be found __here__.

**Solution**

ILLM was used to produce rule-sets on random excerpts of few thousand samples. These were tested on the training set 10% of the size of total training data, and those scoring highest scores in terms of accuracy, were put in the pool for clasifying the test set. Final classification was performed using voting between different models, based on the cost sensitive confusion matrix.

**Score**

There were in total 24 solutions for in the contest. ILLM solution was 17th. KDD Cup 1999 stimulated us to work on new solutions in combining classifiers, and changes in the objective function of the ILLM rule-search algorithm.

### CoIL (Computational Intelligence and Learning) Challenge 2000

**Description**

__CoIL Challenge site__.

**Solution**

The challenge had two tasks which were evaluated separately. Since ILLM methodology is capable of giving efficient and informative classifiers in the form of conjunctions of literals, both the prediction and description tasks were tackled simultaneously. In the experimental phase we have used 5 fold cross validation on the training set to find out the "optimal" set of parameters for the ILLM rule-set search alogrithm, which would produce robust rule-sets with high lift. Final rule-set gave us high lift, but also an informative description of about half-a-dozen distinct customer subgroups.

**Score**

- Prediction task: 9th of 43
- Description task: 2nd of 43
