Rule
A rule is an explicitly specified condition, procedure, or directive that governs behavior, decisions, or outcomes in a defined domain.
Outlier Detection in Python
A rule is an explicitly specified condition or procedure that classifies or responds to data according to predetermined criteria.
- How it is used
- Flags known patterns in records or sorts detector-flagged outliers into categories for investigation.
- How deep it goes
- Works through row-wise tests, immediate flags, weighted scores, and post-detection labels; cautions that thresholds need judgment and tuning.
- Examples
- Uses staff-expense checks and network-session duration and error-rate tests.
- What you can do after
- Build it from scratch to flag specified records or label detector results, then inspect scores for patterns the labels may miss.
Collaborative Software Design: How to facilitate domain modeling decisions
A rule is a prescribed condition or policy that determines permitted behavior or outcomes in a domain.
- How it is used
- Uses rules to expose stakeholder expectations and discover acceptance criteria through collaborative examples.
- How deep it goes
- Explains rule capture, concrete-example testing, and discovery of additional rules through what-if discussions.
- Examples
- Uses cinema seating, “Only 1 ticket per seat,” adjacent reservations, and “No Orphan Seats” as concrete examples.
- What you can do after
- Apply via Example Mapping to document known policies, test edge cases, and turn discussions into clarified rules.
