Avan, S.Si., M.Si., an alumnus of the Mathematics program and a Risk Modeler at Bank Mandiri, began his presentation by discussing the current state of the banking sector, especially in risk management. The talk was part of a guest lecture for the Artificial Neural Networks course with the theme “Credit Risk Modelling” held on December 10, 2024, at the Mathematics Department. With nearly a decade of experience as a risk modeler at Bank Mandiri, Avan shared best and worst practices for building models. Most of the attendees, who were students, paid close attention as they were familiar with the model-building framework, similar to their final thesis projects in the Mathematics Department.

“Next, we’ll discuss issues related to imbalanced datasets and overfitting,” Avan said. These two problems often challenge mathematics students when working on their theses. He explained these issues in a clear and detailed way. The lecture also covered artificial neural networks, which are a popular machine learning model used in risk modeling. The guest lecture was held in a hybrid format, with both students and lecturers from the Mathematics Department of FMIPA UNEJ attending. Continue reading →
