Diff-MN: Diffusion Parameterized MoE-NCDE for Continuous Time Series Generation with Irregular Observations
arXiv:2601.13534v3 Announce Type: replace Abstract: Time series generation (TSG) is widely used across domains, yet most existing methods assume regular sampling and fixed output resolutions. These assumptions are often violated in practice, where observations are irregular and sparse, while downstream applications require continuous and high-resolution TS. Although Neural Controlled Differential Equation (NCDE) is promising for modeling irregular TS, it is constrained by a single dynamics function, tightly coupled optimization, and limited ability to adapt learned dynamics to newly generated
Published in 2026, this research indicates continued advancement in generative AI techniques for challenging real-world data, building on current limitations in time series generation.
Improving time series generation for irregular and sparse data is crucial for robust AI applications in finance, healthcare, and industrial control, where such data is common.
This research introduces methods to overcome limitations of existing models (NCDEs) in handling irregular time series, potentially enabling more accurate and flexible continuous time series generation.
