ImDiffusion: Imputed Diffusion Models for Multivariate Time Series Anomaly Detection

Summary: ImDiffusion uses diffusion-model imputation to capture temporal and cross-variable dependencies for robust multivariate time-series anomaly detection. It leverages intermediate denoised outputs as anomaly signals, yielding SOTA accuracy/timeliness and +11.4% F1 in Microsoft production. (summarized by gpt-5-mini on Feb 09 2026)
