Problem

Scenario

You have finished an analysis and built a model, and now you need to present the results to technical and non-technical stakeholders. Before you share conclusions, you want to confirm that the reported performance is stable, correctly measured, and not driven by a bad split, poor calibration, or a misleading aggregate metric.

Question

How do you validate your results before presenting them?

What Needs Validation

  • Metric stability across folds or resamples
  • Threshold-specific behavior, not just aggregate ranking
  • Calibration of predicted probabilities
  • Uncertainty bounds on key metrics
  • Error patterns hidden by averages
