New CrossTF Diffusion Model Enhances Extreme Event Time-Series Generation

Researchers have introduced Cross-View Time-Frequency Diffusion (CrossTF), a novel framework designed to improve the generation of realistic time-series data, particularly by capturing rare but impactful extreme events. The method leverages discrepancies between time- and frequency-view denoisers, identifying a specific cross-view window where adjustments significantly impact extreme fidelity without compromising overall generation quality. This approach allows for a staged optimization strategy, leading to a 26.1% improvement in extreme fidelity and a 7.4% increase in overall performance compared to existing baselines across seven real-world datasets.

    Cross-View Time-Frequency Diffusion for Extreme-Aware Time-Series Generation

    arXiv:2610.17407v2 Announce Type: cross Abstract: Generating realistic time-series requires faithfully reproducing rare but high-impact extreme events. Existing approaches often rely on specialized representations or extreme-focused training objectives, which may restrict the div…
