You group anonymous delivery measurements without a target label.
Why is supervised accuracy unavailable as the fitting objective?
Retrieve earlier concepts before combining them.
This practice: Retrieve earlier concepts before combining them. Next: Retrieval 2 · K-Means retrieval.
Supporting concepts: Describe clusters in meaningful units →
Remember the idea
Use the inputs and evidence to recover the method. Hints and explained solutions remain collapsed; exact phrasing is not graded.
Hint 1 — Think
Recall what a supervised accuracy calculation would need as its reference.
Hint 2 — Tools
Unlabelled discovery and target-defined correctness.
Hint 3 — Approach
State what is absent and distinguish exploratory descriptions from later external interpretation.
Explained solution
No target class defines a correct answer during fitting. A later comparison with an external reference may aid interpretation, but does not turn the fitting process into supervised prediction.
