GABIL Extensions

• Two new genetic operators
• AddAlternative - generalizes constraints by changing a 0 to a 1
• in an attribute substring 10010 becomes 10110
• This operator was applied with probability .01
• DropCondition - performs more drastic generalization step by replacing all bits for a particular attribute by a 1.
• in an attribute substring 10010 becomes 11111
• The operator was applied with probability .60
• the addition of these operators increased accuracy from 92.1% to 95.2% on a range of datasets
