We introduce TopoPrimer, a framework that makes the global topological structure of the series population an explicit input to any forecasting model. TopoPrimer improves accuracy across diverse domains, stabilizes forecasts under seasonal demand spikes, and closes the cold-start gap. Precomputed once per domain via persistent homology and spectral sheaf coordinates, TopoPrimer deploys per token for fully-trained models and as a lightweight adapter for pre-trained backbones. Of these two components, sheaf coordinates are the primary accuracy driver. Across four public benchmarks on Chronos and…
The continuous growth in data and the increasing complexity of AI models necessitate more robust and accurate forecasting methods to handle evolving patterns and 'cold-start' scenarios effectively.
Improved forecasting accuracy, especially in complex temporal data and 'cold-start' situations, enhances the reliability and applicability of AI in critical operational and strategic domains.
Forecasting models can now explicitly integrate global topological structure, moving beyond traditional feature engineering to improve stability and accuracy across diverse, time-series data.

Wider adoption of advanced topological data analysis in AI forecasting leads to more precise predictive maintenance and resource allocation.
Industries with highly variable demand or 'cold-start' problems experience increased efficiency and reduced waste due to improved model reliability.
The integration of topological context becomes a standard requirement for next-generation AI forecasting platforms, driving innovation in data representation and model architectures.
