The talk introduced 'prediction-domain adaptive evaluation', which involves defining the prediction domain first, constructing validation folds that reflect it (using tools like Area of Applicability, Local Point Density, and kNNDM cross-validation), and summarizing performance weighted by prediction condition prevalence. The workshop provided practical R workflows implementing these ideas. The core message: spatial ML evaluation must answer not just 'how accurate is the model?' but 'where can the model be trusted?' ## Full article daily.dev links to this article rather than hosting it.
