The Forecast Began by Choosing the Planet
An autonomous system assembled public and Earth-observation data on demand, then searched for a task-specific model instead of beginning with a fixed dataset.
Summary
An autonomous system assembled public and Earth-observation data on demand, then searched for a task-specific model instead of beginning with a fixed dataset.
PPE retrieves spatiotemporally relevant covariates from public and Earth-observation platforms, fuses them with foundation-model embeddings, and searches model families with overfitting guards. The authors report mean R-squared gains across 21 US health indicators, national risk and vulnerability measures, a doubling over a baseline for Nigerian food-security downscaling, and 83.3 percent Recall@10 in five retrospective weekly forecasts for the 2026 DRC Bundibugyo Ebola outbreak. Those are author-reported evaluations on selected tasks; an autonomous pipeline does not remove the need to audit data coverage, target validity, uncertainty, or decisions made from its forecasts.
