Nikita Kozodoi holds a M.Sc. degree in Economics and Management Science from the Humboldt University in Berin. Since April 2018, he works as a researcher at the Chair of Information Systems. As part of his master's thesis, he investigated the predictive performance of managerial heuristics compared to machine learning methods in the area of box office forecasting. In the course of his Ph.D., Nikita researches applications for machine learning in credit risk analytics.


Research Interests

Nikita is particularly interested in machine learning and deep learning applications in credit scoring. His work includes such topics as: developing solutions to mitigate the impact of sampling bias on scoring models; performing profit-driven feature selection with multi-objective algorithms; reducing algorithmic discrimination and analyzing the profit-fairness trade-off.
