Zero shot forecasting. Time Series Foundation Models: MOIRAI-2, TimesFM-2.5, and Toto-2, Chronos, MOMENT.

The podcast presents an analysis and comparison of various foundation models designed for time series data. It explains that the initial generation of forecasting foundation models, such as TimeGPT and Chronos, successfully demonstrated the feasibility of zero-shot forecasting. However, the text notes that in practical, real-world applications, fine-tuned baseline models often outperformed these early foundation models. To address this limitation, researchers initially relied on finetuning as a workaround, but this contradicted the core benefit of the zero-shot approach. The document then highlights a crucial advancement, stating that recent upgrades in pretraining and data quality have yielded improved models, like MOIRAI-2 and TimesFM-2.5, which now consistently outperform specialized baselines even when handling complex datasets.
