T2S

Summary

T2S is a text-to-time-series generation model that combines a length-adaptive VAE with a text-conditioned Diffusion Transformer trained through flow matching.

Role In The Wiki

T2S anchors the text-to-series generation branch. It is useful for comparing flow-matching generation interfaces: unlike Sundial, which conditions on numeric history for probabilistic forecasting, T2S conditions on natural-language captions to generate synthetic time-series instances.

It also strengthens the synthetic-data thread because it introduces TSFragment-600K, a fragment-level text-time-series dataset produced by captioning local temporal morphology in existing time-series datasets.

T2S should not be treated as forecasting or action-conditioned world-model evidence: it has no observed-history input and no explicit action, control-input, or intervention channel.
