Prepare the data
Select a licensed target image set and record the pretrained checkpoint’s provenance and restrictions.
Reuse learned features. Check the new domain.
Transfer learning adapts a pretrained representation to a new task. The model’s licence, original preprocessing and overlap with evaluation data are part of the experiment.
Learning concept · Not a validated service
Transfer learning adapts a pretrained representation to a new task. The model’s licence, original preprocessing and overlap with evaluation data are part of the experiment.
A possible application for applied ml classes: Help student teams evaluate whether pretrained features are suitable for a narrow visual task. This extension is not delivered by the supplied starter.
Select a licensed target image set and record the pretrained checkpoint’s provenance and restrictions.
Train a frozen-backbone classifier head, then compare limited fine-tuning with a lower learning rate.
Compare held-out scores and compute cost with a small from-scratch baseline; inspect domain-shift errors.
Provide a model card documenting checkpoint, preprocessing, target data and permitted uses.
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 trains a new random forest and uses no pretrained checkpoint. 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 student teams evaluate whether pretrained features are suitable for a narrow visual task.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
