New method speeds up training for Time Series Foundation Models

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced Synthetic Data Distillation (SDD), a novel training objective for Time Series Foundation Models (TSFMs). SDD enhances pre-training by comparing TSFM outputs to the conditional forecast distribution of synthetic trajectories, rather than just realized future values. This method, which is a form of Rao-Blackwellization, has been empirically validated on TSFMs ranging from 4 million to 2.5 billion parameters. The results show that SDD leads to faster convergence of validation loss and requires fewer training iterations, achieving comparable or improved performance on Gaussian Process data. AI

IMPACT Accelerates the development and deployment of more capable time series foundation models.

    Distillation of Synthetic Data for Time Series Foundation Models

    arXiv:2609.09586v1 Announce Type: new Abstract: Time series foundation models (TSFMs) are increasingly pre-trained on synthetically generated time series trajectories, where the data generating process is known. Current pre-training recipes are based on loss objectives which comp…
