Decision Utility
Decision Utility in the context of production machine-learning systems.
Lessons
Formal explanations, examples, simulations, and checkpoints.
Problem framing, statistics & evaluation
Predict decisions, not just labels
A model score earns its place by improving a declared decision.
Problem framing, statistics & evaluationLabels, availability, and leakage
Train on what the system knew then, label with what became known later.
Problem framing, statistics & evaluationMetric selection by task and decision
Select metrics from the prediction target, decision, error costs, prevalence, slices, horizon, and deployment constraints—not from habit.
Courses & assignments
Dependency-authoritative learning units.
Casebook
Reported facts and course reconstructions.
