FADTI: Revolutionizing Time Series Imputation with Fourier and Diffusion Models
FADTI combines Fourier and Attention-Driven Diffusion for robust multivariate time series imputation, specifically addressing structured missing patterns and distribution shifts. This framework delivers unparalleled accuracy and stability, even with high missing rates, ensuring enterprises operate on complete, high-fidelity data.
Executive Impact & Key Advantages
Implementing FADTI translates into a direct competitive advantage for enterprises. Imagine a 20-30% reduction in data-related operational costs due to fewer errors and more reliable predictive analytics. For real-time systems, this means more accurate anomaly detection and forecasting, preventing costly downtime or missed opportunities. In healthcare, FADTI can improve patient outcome predictions by providing complete, high-quality data from sensor feeds. This technology isn't just about filling gaps; it's about unlocking the full potential of your time-series data.

Time Series Imputation
Enhanced Time Series Imputation
Multivariate Time Series Imputation (MTSI) is crucial for handling missing data due to sensor failures or irregular sampling in diverse applications like healthcare, traffic forecasting, and IoT. Traditional methods often fail to capture complex temporal dependencies or handle high missing rates effectively.
FADTI's Approach: This research introduces FADTI, a novel diffusion-based framework that integrates frequency-informed feature modulation via a learnable Fourier Bias Projection (FBP) module. This design explicitly injects frequency-domain inductive bias into the generative imputation process, enabling adaptive encoding of both stationary and non-stationary patterns.
Key Advantages: FADTI overcomes limitations of existing models by explicitly modeling periodic and trend components, enhancing performance under sparse or irregular missingness, and improving generalization by incorporating structural assumptions. Experiments demonstrate consistent outperformance of state-of-the-art methods, especially under high missing rates.
