arXiv:2605.28867v1 Announce Type: new Abstract: Generating high-quality time-series data is challenging because real-world signals often exhibit multimodal patterns and multiscale dynamics, including oscillations and high-frequency variations. Flow Matching (FM) offers an efficient alternative to diffusion models, but practical implementations typically rely on a single finite-capacity global vector-field estimator. In such heterogeneous temporal distributions, distinct regimes may pass through nearby flow states while requiring incompatible conditional velocities. A monolithic estimator train
The continuous drive for more efficient and accurate generative AI models, especially for complex data like time-series, necessitates innovations like PrismFlow to overcome limitations of existing methods.
Improving time-series generation is crucial for advanced simulations, forecasting, and synthetic data creation across many domains, impacting real-world applications in finance, healthcare, and engineering.
This research introduces a novel approach for Flow Matching that offers superior handling of complex, multimodal, and multiscale time-series data, potentially enabling more realistic and diverse synthetic data generation.

PrismFlow enables more accurate and diverse synthetic time-series data generation by addressing limitations of current flow matching methods.
Improved synthetic time-series data can accelerate research and development in areas like autonomous systems, financial modeling, and drug discovery by providing richer training datasets.
The widespread adoption of such advanced generative models could lead to new forms of data-driven insights and AI applications previously constrained by data scarcity or quality.
