Scope of this mini-segmentation (read first)

A deliberately small exercise (~2.5 hours applied): group applicants WITHOUT the target, name the groups, and turn them into our own classes. Concepts: Unsupervised EDA scope; personas; risk tiers Project A: German Credit applicants (1,000 rows). Target is hidden during clustering and used only afterwards for interpretation. Project B: Optional, same scope: cluster daily load profiles into 3–4 day types (workday, weekend/holiday, heat-wave day).
