Problem

Scenario

You have trained and shipped a machine learning model, and the team wants confidence that its performance will hold up outside the initial offline results. You need a clear evaluation process that catches overfitting, unstable thresholds, and score quality issues before the model affects users.

Question

How do you ensure that your machine learning models are robust and reliable?

What to Evaluate

  • Validation stability across folds
  • Probability calibration quality
  • Threshold-dependent precision and recall tradeoffs
  • Confusion matrix costs by business outcome
