Author a small feature table and compare cluster assignments under alternative scales and starting centres.
Name the expected effect, metric and what would count against the hypothesis.
Record fixtures, source, version, parameters, units, controls and how cases are split.
| Case and split | Baseline result | Changed result | Interpretation |
|---|---|---|---|
Rescaling one unchanged feature can reorganise the clusters; a different initialisation can reach a different local solution.
Record your new case and rerun the original cases after redesign.
Explain the mechanism, one exact result and what would overturn your conclusion.
Two clusters and a Euclidean geometry are assumptions; no category truth is supplied.
Next test: _ . Project filename: _ . Work that is mine and tools I used: ____ .
