Define deployment targets
Specify acceptable accuracy loss, target bit-width (e.g. 8-bit) and latency/size constraints for the release device.
Quantization-aware training. Measure size and accuracy trade-offs.
Quantization-aware training (QAT) simulates low-precision arithmetic during training so the model learns weights and activations robust to fixed-point inference. QAT reduces model size and runtime for edge deployment but requires calibration, careful hyperparameter tuning and validation against accuracy and latency targets.

Quantization-aware training (QAT) simulates low-precision arithmetic during training so the model learns weights and activations robust to fixed-point inference. QAT reduces model size and runtime for edge deployment but requires calibration, careful hyperparameter tuning and validation against accuracy and latency targets.
A proposed application: produce a compact image or audio model for low-latency edge inference where a human reviewer remains responsible for final decisions. This starter does not produce an audit-ready QAT pipeline.
Specify acceptable accuracy loss, target bit-width (e.g. 8-bit) and latency/size constraints for the release device.
Use a real dataset matching the deployment domain and ensure validation splits reflect expected input distributions.
Implement QAT in a deep-learning framework (for example PyTorch) that inserts fake-quantisation nodes during training and monitors accuracy drift.
Measure accuracy, model size and latency on target hardware, then export to a quantised runtime format (ONNX, TFLite) and add monitoring hooks.
The supplied starter builds a scikit-learn pipeline: it creates a synthetic classification dataset with make_classification, fits a StandardScaler plus RandomForestClassifier, and prints a sklearn classification report. It does not implement quantization-aware training, nor does it use PyTorch, fake-quantisation operators, or any model export step.
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(PROJECT_NAME)
print(classification_report(y_test, predictions))The starter uses a RandomForest on synthetic tabular data and contains no quantisation, fake-quantisation nodes, PyTorch training loop, or model export. It cannot validate QAT concepts such as accuracy under fixed-point inference or measure model size/latency after quantisation.
A proposed extension: replace the starter with a small convolutional network trained with PyTorch QAT on a representative image subset, then export an 8-bit ONNX/TFLite model and measure inference latency on target hardware.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
