Define the prediction task
Specify classes (e.g. no DR, mild, moderate, severe) and clinical success criteria such as sensitivity at a fixed false positive rate.
Detect diabetic retinopathy. Assess clinical decision risk.
Automatic diabetic retinopathy detection normally requires retinal fundus images, careful labelling by experts, and image-based modelling with convolutional networks. Important issues include label noise between graders, class imbalance (sight‑threatening vs mild cases), calibration of probability outputs, and clinical review of borderline predictions.

Automatic diabetic retinopathy detection normally requires retinal fundus images, careful labelling by experts, and image-based modelling with convolutional networks. Important issues include label noise between graders, class imbalance (sight‑threatening vs mild cases), calibration of probability outputs, and clinical review of borderline predictions.
A proposed use case is a triage aid in eye clinics: flag exams needing urgent ophthalmologist review while keeping a human reviewer in charge. This starter does not implement clinical triage and must not be used for real patient decisions.
Specify classes (e.g. no DR, mild, moderate, severe) and clinical success criteria such as sensitivity at a fixed false positive rate.
Collect labelled fundus images, apply standard augmentations, and split by patient to avoid information leakage.
Fine-tune a convolutional backbone on training images, track calibration and per-class sensitivity during validation.
Report sensitivity, specificity, AUC and calibration; have clinicians review failure cases before any deployment.
The supplied starter generates a synthetic numeric classification dataset with sklearn.make_classification, fits a StandardScaler + RandomForest pipeline on tabular features, and prints a scikit-learn classification report. It does not load or process retinal images, nor does it implement image-based deep learning required for diabetic retinopathy detection.
model = Pipeline(
steps=[
("scale", StandardScaler()),
("classifier", RandomForestClassifier(n_estimators=250, random_state=RANDOM_STATE)),
]
)
model.fit(X_train, y_train)
predictions = model.predict(X_test)The code uses synthetic tabular data (make_classification) rather than retinal fundus images and therefore cannot validate diabetic retinopathy detection. There is no image preprocessing, no ophthalmic labels, and no clinical validation; performance on the synthetic task does not transfer to the clinical problem.
A proposed extension is a pilot triage tool that ingests fundus images, produces calibrated risk scores for sight‑threatening retinopathy, and surfaces borderline cases for clinician review.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
