Guest Lecture by Practitioners of Mathematics Department: Artificial Neural Networks by Avan, Risk Modeler Bank Mandiri

News, Student, , , ,

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 →

News, Student, , , , ,

The Data Science Research Group (KeRis DSc) held a book discussion on Variable Selection in Predictive Modeling for Statistics and Machine Learning on December 2nd. The event featured Dr. Bagus Sartono, S.Si., M.Si., Chairman of FORSTAT and Head of the Statistics Department at IPB University, and Prof. Dr. Vita Ratnasari, S.Si., M.Si., a Professor of Statistics at the Sepuluh Nopember Institute of Technology. The event was held at the UNEJ Entrepreneurship Building and was opened by the Dean of the Faculty of Mathematics and Natural Sciences (FMIPA) at UNEJ and President of IndoMS, Prof. Drs. Dafik, M.Sc., Ph.D. In his speech, the Dean praised KeRis DSc for initiating the book discussion to promote a culture of mathematical literacy. “This is a very interesting book, discussing machine learning which will eventually lead to ‘black box’ models,” he said.

The Dean explained that the black box approach could speed up coding when developing application programs. “I hope this book discussion will be useful for the advancement of mathematics, especially statistics, and inspire other research groups in FMIPA,” he added. The book *Variable Selection* is written by Bagus Sartono, Alfian Futuhul Hadi, Evi Ramadhani, and Akbar Rizki. Prior to the discussion, Dr. Mohamat Fatekurohman, S.Si., M.Si., Chair of KeRis DSc, expressed his appreciation to the team for organizing the event in such a short time. He mentioned that after a period of inactivity, DSc is starting up book discussions again, with plans for guest lectures and seminar series in the future. Continue reading →
