Researchers have developed Seq-Flow, a novel conditional flow model designed for efficient probabilistic forecasting. This model utilizes an ODE to transport samples from a previous forecast distribution to an updated one, significantly reducing the number of sampling steps required. To mitigate error accumulation from sequential updates, Seq-Flow employs a self-rollout training method where a moving average copy of the model initializes subsequent training. Experiments demonstrate Seq-Flow's effectiveness in particle-accelerator beam spill forecasting, achieving a 65% reduction in CRPS with a limited sampling budget, and maintaining accuracy over hundreds of updates.
