ATM cash flow prediction and replenishment optimization with ANN
(Kırıkkale Üniversitesi, 2019) Özpınar, Alper; Serengil, Sefik Ilkin
ATMs are physical interaction points between financial institutions and real customers. Storing physical cash causes renouncing to get interested. On the other hand, customer satisfaction requires to store the necessary cash amount. This concern becomes even more critical for countries having high-interest rate and overnight interest rates are higher. In this paper, we will show that daily cash withdrawals are predictable and we will propose a cost function for replenishment optimization. Experiments show that proposed model decrease idle balance dramatically.
HyperExtended LightFace: A Facial Attribute Analysis Framework
(Institute of Electrical and Electronics Engineers, 2022) Serengil, Sefik Ilkin; Özpınar, Alper
Facial attribute analysis from facial images has always been a challenging task. Its practical use cases are very different. This paper mentioned how to build machine learning models with facial image data for age, gender, facial expression, and race/ethnicity prediction tasks. A fully coded open-source software framework was also developed and published with those functionalities.
