ImConDM: Accurate MTS Anomaly Detection Integrating Imputation With Conditional Diffusion Models

Multivariate Time Series (MTS) anomaly detection is critical for various applications. Yet, most existing methods rely on forecasting or reconstruction-based frameworks, which suffer from inherent uncertainties in handling complex MTS data. The recently emerging imputation-based anomaly detection leverages partial obse...

Joint Beamforming and Segmentation Optimization for Segmented RIS-Assisted Cell-Free mMIMO Systems Under Perfect and Imperfect CSI

The integration of reconfigurable intelligent surface (RIS) technology with cell-free massive MIMO (CF mMIMO) enhances wireless network sum-rate performance. This paper proposes a novel segmented RIS-assisted CF mMIMO architecture for downlink transmission, where RIS elements within each segment share a common reflecti...
