-^Bachelor's/ Master's Thesis: Interactive Subgroup Discovery in Cohort Study Data^^  
-|  {{:offers:diplomthemen:ba_interactive_subgroup_discovery.png? 120}}| Subgroup Discovery Algorithms aim to find coherent, easy-to-interpret rules concerning a target variable and a quality criterion. For instance, in a medical application rules in the form of //(glucose > 7.0 mu/l AND sex = women) --> Hepatic Steatosis = TRUE// may be found. These rules describe subpopulations whose distribution with respect to an outcome considerably deviates from the whole population. However, the process of finding an actually interesting subset of rules is hampered by a) a high redundancy towards instance coverage, b) tedious parameter tuning and c) a necessary manual post-filtering step of the results and means a considerable effort for the data analyst. Therefore, it is necessary to involve the application expert into the subgroup discovery process. The target of the project is to implement an interactive Subgroup Discovery algorithm which incorporates user feedback during candidate generation within a beam search to increase the quality of the returned set of rules with respect to the above mentioned problems.|
