Collect and label pairs
Assemble a dataset of image pairs with same/different labels and reserve disjoint identities for validation to avoid identity leakage.
Verify faces match. Decide similarity with thresholds.
Face verification determines whether two face images belong to the same person. Practical issues include pose and illumination variation, ageing, low resolution, and choosing an operating threshold to balance false accepts and false rejects. Evaluation must report verification metrics (TAR/FAR, ROC) and operational behaviours such as latency and failure modes for unseen subjects.

Face verification determines whether two face images belong to the same person. Practical issues include pose and illumination variation, ageing, low resolution, and choosing an operating threshold to balance false accepts and false rejects. Evaluation must report verification metrics (TAR/FAR, ROC) and operational behaviours such as latency and failure modes for unseen subjects.
A proposed application is a supervised access-control audit tool that flags likely matches for a human security reviewer rather than making automatic entry decisions. Because biometric decisions affect privacy and security, a human should remain in charge.
Assemble a dataset of image pairs with same/different labels and reserve disjoint identities for validation to avoid identity leakage.
Use a pretrained face-embedding network (e.g. ArcFace/FaceNet) or train one so each face maps to a fixed-length vector for pairwise comparison.
Compute distances for validation pairs, plot ROC, choose an operating threshold, and report TAR at fixed FAR and confusion behaviour across demographics.
Serve embeddings and similarity scores via an API, surface borderline cases to human reviewers, and monitor drift, latency and false-accept events.
The supplied starter loads sklearn's digits dataset, splits it, fits a RandomForestClassifier to digit images, prints a classification report and shows a confusion matrix. It does not use face images, compute face embeddings, or perform pairwise verification.
model = RandomForestClassifier(n_estimators=300, random_state=42)
model.fit(X_train, y_train)
predictions = model.predict(X_test)
print(PROJECT_NAME)
print(classification_report(y_test, predictions))
The code trains a RandomForest on the MNIST-like digits dataset; it contains no face images, no embedding model, and no pairwise match/threshold logic required for face verification.
A proposed extension is a small pilot that uses a pretrained face-embedding model to compare pairs, selects an operating threshold on a held-out identity-disjoint set, and surfaces low-confidence pairs to a human reviewer for verification.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
