Censoring
Censoring in the context of production machine-learning systems.
Lessons
Formal explanations, examples, simulations, and checkpoints.
Problem framing, statistics & evaluation
Labels, availability, and leakage
Train on what the system knew then, label with what became known later.
Problem framing, statistics & evaluationBaselines and honest splits
A baseline sets the floor; an honest split keeps the ruler straight.
Problem framing, statistics & evaluationMetrics, thresholds, and calibration
Measure ordering, repair probability meaning, then choose the policy the operation can actually run.
Courses & assignments
Dependency-authoritative learning units.
Casebook
Reported facts and course reconstructions.
