When Context Compensates for Sparse Event History: AlphaEarth for Spatio-Temporal Point-Process Forecasting
arXiv:2607.01082v1 Announce Type: new Abstract: Spatio-temporal point-process models must often generalise across space when local event histories are sparse. We study whether exogenous spatial context can compensate in such regimes. Using a fixed log-Gaussian Cox process backbone, we compare an event-only model with the same model augmented by AlphaEarth embeddings as linear spatial context. We evaluate spatial transfer on emergency medical services (EMS) forecasting across eight held-out regions, fixed forecast anchors, and a sweep over history length $w$, using only AlphaEarth (AE) embeddin
The continuous advancements in AI and machine learning techniques, particularly in integrating complex contextual data, are enabling more sophisticated real-time predictive models.
This research is important for strategic readers as it demonstrates a critical improvement in forecasting rare events, which has direct implications for resource allocation, emergency response, and operational efficiency in various sectors.
The ability to compensate for sparse event histories with exogenous spatial context fundamentally changes how predictive models can operate in data-poor environments, expanding the applicability of AI-driven forecasting.
