Constrained Posterior Sampling: Time Series Generation with Hard Constraints

NeurIPS 2025poster

Generating realistic time series samples is crucial for stress-testing models and protecting user privacy by using synthetic data. In engineering and safety-critical applications, these samples must meet certain hard constraints that are domain-specific or naturally imposed by physics or nature. Con…

Time Weaver: A Conditional Time Series Generation Model

ICML 2024spotlight

Imagine generating a city’s electricity demand pattern based on weather, the presence of an electric vehicle, and location, which could be used for capacity planning during a winter freeze. Such real-world time series are often enriched with paired heterogeneous contextual metadata (e.g., weather an…
