Preface
This volume contains the papers presented at the forth international conference RTA-CSIT
2021: Recent Trends and Applications in Computer Science and Information Technology held
on May 21-22, 2021 in Tirana, Albania. Due to the ongoing COVID-19 pandemics situation,
this edition has been mostly virtual.
    The conference has been organized once again by the Department of Informatics, Faculty
of Natural Sciences, University of Tirana, Albania.
    Despite the ongoing pandemics, the conference managed to achieve its continuity with many
returning researchers from previous editions and also research works presented by first time
participants. Participants of this edition presented research works from Albania, Italy, Turkey,
North Macedonia, Croatia, Romania, India, and Nigeria.
    50 papers were submitted for peer review to this conference. Out of these 19 were accepted
as full papers and 10 were accepted as short papers.
    In this edition of the conference an interestingly dominant topic was the application of deep
learning approaches in medicine related scenarios. Other than it, further works were presented
in the core topics of the previous editions: e-Government, e-Business, e-Learning, Smart Cities,
Networking, and Cloud Computing.
    Looking forward for future collaborations, we would like to thank you all participants and
reviewers for their contributions.
