Paper by ECE-NTUA Ph.D. student Maria Athanasiou receives the Best Student Paper Award in IEEE BIBE 2020

ECE-NTUA Ph.D. student Maria Athanasiou received the Best Student Paper Award in the 20th IEEE International Conference on BioInformatics And BioEngineering (BIBE) that was held virtually on October 26-28, 2020.

The award-winning paper entitled: “An Explainable XGBoost-Based Approach Towards Assessing the Risk of Cardiovascular Disease in Patients with Type 2 Diabetes Mellitus” was co-authored by Maria Athanasiou, Konstantina Sfrintzeri, Konstantia Zarkogianni, Anastasia Thanopoulou, and Konstantina Nikita.

The paper proposes an explainable personalized risk prediction model for the fatal or non-fatal CVD incidence in individuals with Type 2 Diabetes. An explainable approach based on the eXtreme Gradient Boosting (XGBoost) and the Tree SHAP (SHapley Additive exPlanations) method is deployed for the calculation of the 5-year CVD risk and the generation of individual explanations on the model’s decisions. Data from the 5- year follow up of 560 patients with T2DM are used for development and evaluation purposes. The obtained results (AUC=71.13%) indicate the potential of the proposed approach to handle the unbalanced nature of the used dataset while providing clinically meaningful insights about the model’s decision process.
