PhD Dissertation Defence – Dr. Argyro Argyrou
Congratulations to Dr. Argyro Argyrou, member of the CONNECTING Project, on the successful defence of her PhD dissertation, presented during an open lecture. Her doctoral research, entitled “Addressing the Accuracy Paradox in Archaeological Ceramic Surface Detection Using Low-Altitude, High-Resolution Remote Sensing Data”, makes a significant contribution to archaeological remote sensing and computational archaeology by integrating UAV-based high-resolution and multispectral imagery with advanced machine learning techniques. By addressing the accuracy paradox in imbalanced archaeological datasets through boosting algorithms (AdaBoost, XGBoost), decision-threshold optimisation, and tailored evaluation metrics, her work substantially improves the detection of ceramic surface remains, enhancing both accuracy and survey efficiency. Grounded in extensive empirical research across three Mediterranean case studies (Alampra and Kofinou in Cyprus, and Megara in Greece), the dissertation demonstrates strong real-world archaeological impact and introduces a novel metric, Sensitivity Archaeological Detection (SAD), offering a robust framework for future research in cultural heritage and remote sensing. We warmly congratulate Dr. Argyrou on this outstanding achievement and wish her every success in her future academic and professional journey.
