Module 3 Assignment: Preprocessing and augmentation

Scenario

You are advising a radiology service deciding whether an imaging AI should advance from retrospective review to supervised pilot use. The stakeholders are: radiologist, imaging technician, compliance officer, and patient safety lead.

Task

Answer the module question: Which transformations preserve clinical meaning?

Use the module lab and course readings to produce: imaging model evidence packet with preprocessing notes, validation limits, and clinical handoff risks focused on preprocessing and augmentation: Apply preprocessing and document risks..

Required Evidence

• Define the decision or system boundary in one paragraph.

• Identify the dataset, proxy data, or evidence source you used: synthetic 8x8 grayscale image arrays with a small bright lesion pattern and non-lesion variation.

• Compare at least two alternatives, baselines, policies, or designs.

• Report one quantitative result or structured scoring table.

• Explain two failure modes and one mitigation for each.

• State what additional evidence would be required before real deployment.

Submission

Submit the completed notebook plus a 900-1200 word memo. The memo must include clear headings for context, method, evidence, risks, recommendation, and open questions.

Acceptance Criteria

Your submission is complete only if another reviewer can reproduce your reasoning from the evidence you provide. You do not need production-grade data, but you must be explicit about proxy-data limits and what would change with real institutional data.
