Evaluation
Validation Set
A held-out portion of data used to tune your model during development, separate from both training and final test data.
Definition
A subset of data reserved for evaluating model performance during training and hyperparameter tuning. Not used for training or final evaluation. Prevents overfitting to the test set.
Why it matters
The guardrail that prevents you from inadvertently cheating on your test set, essential for honest model evaluation.

Area Under the Curve (AUC)
A score from 0 to 1 that tells you how good your model is at distinguishing between two things (like spam vs. not spam).
Conformal Prediction
A technique that tells you not just what the AI predicts, but how confident it is, with a mathematical guarantee.
