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 […]

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 […]

Combining Client-Based Anomaly Detection and Federated Learning for Energy Forecasting in Smart Buildings
In today’s interconnected world, energy consumption forecasting faces challenges due to client-side anomalies in time-series data. Federated Learning (FL) offers a decentralized solution by forecasting without directly accessing user data. However, the effectiveness of the global model can decline if local anomalies are not properly managed. We propose our lightweight framework EIF-FL: Elliptic envelope and […]

Improving Image-Based Tool Detection in Industrial Workstations using Data Augmentation
Within the framework of Industry 5.0, affordances enable intuitive and adaptive interactions between operators and their industrial work environments. Accurately perceiving these affordances enhances overall production performance, safety, and operator effectiveness. This paper focuses on the initial step of a larger affordance characterization pipeline: detecting tools used by operators during manual assembly tasks. To address […]

Synthetic Data-Driven Augmentation for Precise 6-DoF Pose Estimation of Building Components in Automated Facility Inspections
This paper tackles the challenge of automating facility inspections by detecting building components, estimating their six-degree-of-freedom (6-DoF) poses (position and orienta tion), and comparing these estimations to Building Information Modeling (BIM) ground truth data. Vision based Deep learn ing methods offer promising results in pose estimation. They rely heavily on large annotated image datasets for […]
