arXiv:2605.24055v1 Announce Type: new Abstract: Real-world time-series data in industrial sensing, healthcare, and energy systems is often corrupted by a mixture of Gaussian noise and occasional large-magnitude impulse outliers. For tasks that depend on local shape, such as ECG morphology analysis and battery degradation monitoring, the main requirement is not only low reconstruction error but also preservation of derivative peaks and task-critical features. We propose Cascade-KDE, a training-free restoration framework for corrupted time series. The method first estimates a two-dimensional tem
The proliferation of real-world time-series data from diverse industrial, healthcare, and energy systems necessitates increasingly robust methods for data cleaning and analysis, prompting new research in this area.
Reliable time-series data restoration is critical for various high-stakes applications, ensuring accuracy in critical tasks like medical diagnostics and industrial monitoring, which impacts operational efficiency and public safety.
The development of robust, training-free restoration frameworks like Cascade-KDE could significantly improve the quality and trustworthiness of time-series data used in AI applications, especially where data is frequently corrupted.
