Unsupervised Learning, Recommendation Systems

I am currently enrolled in the Data Science postgraduate program at the National and Kapodistrian University of Athens, with a specialization in Artificial Intelligence and Big Data.

Simultaneously, I am working as a research associate at the Athena Research Center. My work in the lab involves deep and unsupervised learning in recommender systems.

I hold a B.Sc. in Informatics and Telecommunications from the University of Peloponnese, where I completed my thesis with the title "Simulation of a Quantum Telecommunication System", where we explored the endless possibilities for information propagation that lie within the properties of fundamental particles alone.
