Emerging Methodologies in Economics and Finance

Machine Learning

Complex Networks

Econometrics

THE TEAM. Our research team operates within the Department of Economics, Democritus University of Thrace, Greece. Our research efforts were funded by a Research Grant from the European Union (Research Funding Program THALES) under the title “Study and Forecasting of Economic Data Using Machine Learning”, MIS 380292. Also, two PhD candidates are funded for their research from Hellenic Foundation for Research & Innovation (H.F.R.I.) and State Scholarship Foundation (ΙΚΥ).

MEMBERS. The research team is led by associate professors Periklis Gogas an economist (B.A., M.A., Ph.D.) and Theophilos Papadimitriou a mathematician (B.A.) and electrical engineer (M.Sc., Ph.D). Two Post Docs and six PhD candidates are actively working for the team.

RESEARCH INTERESTS. Our group's research interests include both classic Econometrics and also emerging methodologies of as they are applied to Economics and Finance. We currently work with: a) Machine Learning: Support Vector Machines for Classification and Regression and Deep Learning Architectures and b) Complex Networks: Threshold – Minimum Dominating Set, Weighted Dominating Set, and Multivariate Networks.
