About me

I am a Ph.D. candidate at the Remote Sensing Laboratory at the National Technical University of Athens under the supervision of Konstantinos Karantzalos and Nikos Komodakis. My research focuses on self-supervised learning and explainable AI.
I completed my Master's in Mathematical Modeling at the National Technical University of Athens and a Bachelor of Mathematics at the University of Athens.

I serve as a reviewer at CVPR, IJCV, IEEE TNNLS, Neural Networks, IEEE GRSL, IEEE Access.

Keep It SimPool: Who Said Supervised Transformers Suffer from Attention Deficit?
We developed a universal attention-based pooling mechanism called SimPool to replace default pooling strategies in both convolutional and transformer encoders, significantly improving performance and generating high-quality attention maps for both supervised and self-supervised settings.

What to Hide from Your Students: Attention-Guided Masked Image Modeling
We introduce a novel masking strategy, called attention-guided masking (AttMask), and we demonstrate its effectiveness over random masking for dense distillation-based MIM.

MARIDA: A benchmark for Marine Debris detection from Sentinel-2 remote sensing data
We present Marine Debris Archive (MARIDA), the first open-access dataset based on the multispectral Sentinel-2 (S2) satellite data, which distinguishes Marine Debris from various marine features that co-exist.

HOW CHALLENGING IS THE DISCRIMINATION OF FLOATING MATERIALS ON THE SEA SURFACE USING HIGH RESOLUTION MULTISPECTRAL SATELLITE DATA?
We explore the ability to discriminate marine debris from other floating materials and sea features using high-resolution multispectral satellite data. To perform our analysis, we utilized the open-access Marine Debris Archive (MARIDA). We indicate that the spectral information alone is insufficient to distinguish marine plastic from other floating materials which exhibit similar spectral behavior, such as vessels.

Evaluating explainable artificial intelligence methods for multi-label deep learning classification tasks in remote sensing
We evaluated quantitatively and qualitatively different aspects of ten XAI methods. We assess XAI methods’ performance for multi-label classification tasks in BigEarthNet and SEN12MS datasets employing various metrics. We extracted significant insights regarding models’ decisions as well as datasets’ composition and conclude that Occlusion, LIME and Grad-CAM were the most interpretable methods for the specific multi-label remote sensing classification task.
