Reconstruction-Based Methods for Multivariate Time Series Anomaly Detection : A Review and Taxonomy
Reconstruction-based methods have become a central paradigm for unsupervised multivariate time series anomaly detection (MTSAD), especially in the context of cyber-physical and industrial control systems. Their ability to learn normal patterns and detect deviations without supervision makes them highly suitable for safety-critical environments. In this work, we conduct a structured review of recent deep learning […]

The CG-MER dyadicmultimodal dataset for spontaneous french conversations: annotation, analysis and assessment benchmark
Emotion recognition is crucial for enhancing human-computer interaction systems. However, the development of robust methodologies for French emotion recognition is hindered by the scarcity of labeled, interactive multimodal datasets. In this work, we outline the acquisition and annotation procedures and provide an evaluation benchmark for the Card Game-based Multimodal EmotionRecognition (CG-MER)dataset thatwedesigned to capture spontaneous […]

Information Fusion for Real-Time Occupancy Estimation Using CO2 Dynamics and PIR Sensors in Smart Building
Real-time estimation of occupants number in buildings is crucial for managing and reducing the energy consumption of HVAC systems. Currently, estimation is mainly performed using black box models. These models require large datasets with ground truth values, which are often unavailable. Due to the difficulty to dynamically modeling occupancy change, an approach combining gray box […]

Organizing Open Social Innovation for Grand Challenges: Unlocking the Potential of Open Spaces
Open Social Innovation (OSI) is gaining increasing attention in discourses among scholars and practitioners as a new approach to addressing grand challenges. However, little is known about how to organize such OSI efforts. To address this gap, this article explores the role of open spaces, especially fabrication laboratories (fab labs), in orchestrating and scaling OSI […]

MHeedra: Putting Duplication-Enabled Task Scheduling Within Heterogeneous Multi-User Edge-Cloud Platforms to Work
Meeting task performance requirements within edge-cloud computing platforms is difficult due to heterogeneous processing, transmission capabilities, and the multiplicity of optimization opportunities. Edge-cloud platforms fill the computing continuum gap and alleviate data-locality performance issues from offloading tasks. Indeed, additional computing resources disseminated across the network but close to the data source help decouple the inherent […]

BI2PV Simulator for Optimized BIPV Design in Industrial Buildings
The integration of photovoltaics (PV) into industrial buildings remains inhibited by the lack of unified tools that reconcile architectural constraints, energy performance, and economic viability. We present Industrial Building Integrated PV (BI²PV) simulator, an interactive simulator developed with MATLAB App Designer, encompassing the entire workflow: import and interpolation of NSRDB (National Solar Radiation Database) data […]

Sparse space-heterogeneous, physics-constrained PDE reconstruction for defect identification through low-frequency mechanics
This contribution explores an application of automatic PDE identification for nondestructive testing. Defect localization is traditionally performed via the identification of the spatial distribution of a well-chosen physical property, which is assumed to be impacted by the defect in question. Defects whose impact on physical properties is unclear may thus cause the identification approach to […]

Towards Eco-Efficient AI: Hybrid Data Strategies for BIPV Energy Prediction
Accurate prediction of energy production from building-integrated photovoltaic (BIPV) systems is essential for optimizing building energy use and supporting decarbonization strategies. Synthetic data provides a valuable foundation for model development, particularly when real measurements are limited, but validation on operational systems remains critical for reliable deployment. In this study, we propose a hybrid data approach, […]
