Prepare the data
Define an import format for held-out labels, predictions, scores and non-sensitive example identifiers.
Bring the metrics back to the examples.
An evaluation dashboard should connect aggregate scores to the cases that produced them. Class balance, label ordering and threshold selection must remain visible when comparing models.

A possible application for small ml teams: Help small ML teams review a model together before deciding whether to run a pilot. This extension is not delivered by the supplied starter.
Define an import format for held-out labels, predictions, scores and non-sensitive example identifiers.
Compute per-class precision, recall, F1, confusion matrices and score curves where available.
Verify results against hand-calculated fixtures, including absent classes and zero predicted positives.
Build a read-only evaluation view with dataset version and exportable error summaries.
The supplied starter creates 800 synthetic binary-classification rows with ten numeric features. It makes a stratified train/test split, fits a scaled RandomForestClassifier pipeline and prints a classification report.
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)
print(classification_report(y_test, predictions))The source prints a terminal classification report; it does not provide a dashboard. Synthetic binary classification does not establish performance on the proposed application. The source report uses one split; it supplies no deployment or real-world validation.
Proposed extension: Help small ML teams review a model together before deciding whether to run a pilot.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
