Cover Learner using Integer Programming Version 3 (CLIP3)

The pseudocode of theCLIP3 machine learning algorithm is:

Given the POSitive and NEGative training sets and the threshold values do:

Phase I

1. Do for all NEGative examples: 1) generate BINary matrix by comparing matrix POS with negI where i = 1, ..., N, and N is the number of NEGative examples
2) solve the corresponding integer programming (IP) model
3) split the matrix of POSitive examples based on the features indicated by the IP solution and eliminate redundant matrices

Phase II
1. Generate the BINary template matrix (TM)
2. Solve the TM BINary matrix using corresponding IP model
3. Backproject matrices selected in step 2
4. Convert each resulting matrix to IP model and solve
5. Generate rules based on IP solutions
Phase III 1. Find the best rule
2. Eliminate positive examples covered by the best rule and go to Phase I
CLIP3 incorporates three thresholds: Following is an example of the CLIP3 Algorithm:
