Write a model card and human decision plan
See this course’s project requirements
Evaluate the fictional box classifier and document its evidence and use boundaries in a model card.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Define the prediction task, baseline and human decision boundary.
- Document feature/label meaning and independent training/evaluation records.
- Compare two thresholds and freeze the chosen model.
- Calculate confusion counts, accuracy, precision and recall against a baseline.
- Report the separate condition audit and a targeted next evaluation step.
Review and revise
Use these criteria to check your work and choose what to improve.
- Concepts: features, labels, training and decisions remain distinct.
- Evaluation: arithmetic and denominators match the original records.
- Judgment: small samples and uneven performance are not overstated.
- Accountability: use boundaries and further evidence needs are concrete.

The idea in everyday life
A model should travel with information about what it was built to do and how it was evaluated. Without that context, a small demonstration can acquire unjustified authority when copied into another workflow. Your final artifact reuses the task, data, selected threshold, metrics and condition audit. It does not require a hosted model, chatbot prompts or an external AI account.
A model card is a short record of what a model does, how it was tested, its limits, and how its results may be used.
One step at a time.
Use the sample or information you have permission to use. Keep your work as you go. You can pause between steps.
- 1
Write a model card headed "Practice box classifier, threshold 3." State the input, predicted label, training procedure and frozen rule so a reader can reconstruct the model without software.
- 2
Include the four training rows and eight evaluation rows, identifying their different roles. Report the model’s three test metrics and always-no baseline, with raw confusion counts next to percentages.
- 3
Attach the separate lighting audit and its small-sample limitation. Explain that scuff count is incomplete information and that neither perfect training performance nor the holdout improvement establishes production readiness.
- 4
Define the human decision plan for this course: inspect and discuss errors only; do not automate real shipment, safety or people-related decisions. For a future authorized trial, name an owner, review instructions and stop conditions before use.
- 5
Write a monitoring question such as whether new lighting or measurement methods change error rates. Assemble the outputs into a reproducible card and finish with one next data-collection or evaluation action that addresses a documented gap.
See how it works.
Fictional model card summary: "Predict damaged from scuff count using yes when scuffs>=3. Selected from two candidate thresholds on four training boxes. On eight separate boxes: TP=3, TN=2, FP=2, FN=1; accuracy=62.5%, precision=60%, recall=75%; always-no accuracy=50%. A separate lighting audit found uneven recall with very small groups. Use is limited to classroom analysis of invented empty boxes. No operational decision is authorized. Next step: evaluate more consistently measured boxes across lighting conditions before considering a supervised trial." The card makes the limited evidence understandable and keeps the model’s simple prediction separate from any consequential action.
Did you cover these?
- Rule and data roles are reproducible.
- Raw counts accompany metrics and baseline.
- Use limits, owner questions and stop conditions are explicit.
What to finish
A complete model card with reproducible data, metrics, limits and human decision boundaries.
Watch for this
Presenting a classroom model as a certified, fair or production-ready AI system.
How can I tell I understand it?
A reviewer can reproduce the rule and metrics and identify the next evidence needed.
