Our lab member and PhD candidate, Stelio Bompai has successfuly submitted “Diffusion-based Data Augmentation for Short-Term Multivariate Energy Prediction in Data-Scarce Scenarios” on CAI 2026(https://www.ieeesmc.org/cai-2026/).
This work explores diffusion-based generative models as a data augmentation strategy using the ETTh1 multivariate energy dataset, evaluating point and quantile forecasting across XGBoost, LSTM, and BiLSTM architectures, with synthetic data selectively added to neural models. Results show that BiLSTM benefits significantly from diffusion-based augmentation, achieving up to 15.3% reduction in RMSE and 8.1% reduction in MAE, along with consistent improvements in quantile forecasting, while LSTM performance deteriorates across all synthetic-to-real data ratios. Bias–variance analysis suggests that the improvements mainly stem from variance reduction at moderate levels of augmentation, whereas excessive synthetic data can introduce bias and degrade performance.
Organization of SIDS 2026 Workshop
SIDS 2026 aims to bring together researchers and practitioners from mobile data management, artificial intelligence, cybersecurity, and smart city systems to explore novel approaches, architectures, and methodologies for building secure, trustworthy, and intelligent Data Spaces.
Accepted papers will be published in the MDM 2026 Workshop Proceedings and published by IEEE.

Organization of MuseKDE 2026 Workshop
The explosion of tracking technologies - from GPS, AIS, cameras, RADAR, LiDAR, to satellite systems - has created vast but fragmented mobility datasets. Transforming these heterogeneous data streams into reliable knowledge remains a major challenge. To this end, we are happy to announce a novel workshop on Multi-Sensor Trajectory Knowledge Discovery and Extraction, namely MuseKDE. We invite full papers (6 pages) and short/vision papers (2–4 pages). The venue will be co-located with IEEE MDM 2026 in Athens, Greece.

Secondment at ECL
We’re pleased to welcome Farzana Chowdhury and Takoua Jradi from École de technologie supérieure (Canada), who have just started their 3-month secondments at our premises ICCS - NTUA. During their stay, Farzana and Takoua will work on advanced research on FoundationModels and #LargeLanguageModels (LLMs), focusing on the challenging problem of #darkVessels within the vessel monitoring use case of the MUSIT project. Their work will contribute to improving situational awareness and intelligence in maritime environments. Great to have you on board — we look forward to an inspiring and productive collaboration!
