concept:temporal-splits
Temporal Splits
Temporal Splits in the context of production machine-learning systems.
Lessons
Formal explanations, examples, simulations, and checkpoints.
Problem framing, statistics & evaluation
Baselines 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.
Problem framing, statistics & evaluationUncertainty and online experiments
Uncertainty tempers the estimate; randomization tests the cause; guardrails protect the product.
Courses & assignments
Dependency-authoritative learning units.
Casebook
Reported facts and course reconstructions.
