The transjugular intrahepatic portosystemic shunt (TIPS) is an interventional treatment for cirrhotic patients with portal hypertension. In the light of our medical staff's experience, the consequences of the TIPS are not homogeneous for all the patients and a subgroup of them dies in the first six months after the TIPS placement. Actually, there is no risk indicator to identify this group, before treatment. An investigation for predicting the survival of cirrhotic patients treated with TIPS is carried out using a clinical database with 107 cases and 77 attributes. Naive-Bayes, C4.5 and CN2 supervised classifiers are applied to identify this group. The application of several Feature Subset Selection (FSS) techniques has significantly improved the predictive accuracy of these classifiers and considerably reduced the amount of attributes in the classification models. Among FSS techniques, FSS-TREE, a new randomized algorithm inspired on the EDA (Estimation of Distribution Algorithm) paradigm, has obtained the best accuracy results.
