arXiv:2603.29981v3 Announce Type: replace Abstract: Reliable estimation of predictive performance is essential for spatial environmental modeling, where machine-learning models are used to generate maps from unevenly distributed observations. Standard cross-validation (CV) assumes that validation data are representative of prediction conditions across the target domain. In practice, this assumption is often violated due to preferential or clustered sampling, leading to biased performance and uncertainty estimates. We introduce a deployment-oriented validation framework based on weighted CV tha
The increasing deployment of machine learning in critical spatial environmental modeling demands more reliable performance estimation methods to avoid biased outcomes.
Accurate spatial prediction is crucial for effective environmental management, resource allocation, and policy making, where biased models can lead to significant errors and misinformed decisions.
A new framework for validating spatial prediction models that accounts for often-violated assumptions of representative validation data, promising more robust and reliable performance estimates.
