Collect and preprocess images
Assemble a representative, licensed image set, resize and normalise pixels, and split a held-out validation set for FID and visual checks.
Generate images with DCGAN. Judge visual fidelity.
Deep convolutional GANs (DCGANs) learn a generator and discriminator pair to produce realistic images from noise. Key challenges include dataset curation, mode collapse, training instability, and meaningful evaluation such as FID or human perceptual studies.

Deep convolutional GANs (DCGANs) learn a generator and discriminator pair to produce realistic images from noise. Key challenges include dataset curation, mode collapse, training instability, and meaningful evaluation such as FID or human perceptual studies.
A proposed application is synthetic-image augmentation for rare classes in a vision dataset, to help downstream classifiers generalise. This extension is not delivered by the supplied starter code.
Assemble a representative, licensed image set, resize and normalise pixels, and split a held-out validation set for FID and visual checks.
Define generator and discriminator CNNs (transposed convolutions and strided convs), choose loss (e.g. BCE or hinge), and train with monitored checkpoints.
Compute FID and Inception Score on held-out data, and inspect samples for mode collapse and artefacts; include human review of a sample grid.
Export generator weights (ONNX), add simple sampling API, and monitor sample quality and input distribution drift in production.
The supplied starter loads scikit-learn's digits dataset, splits it, fits a RandomForestClassifier, prints a classification report and displays a confusion matrix. It does not implement any GAN, generator, discriminator, or DCGAN training loop.
X_train, X_test, y_train, y_test = train_test_split(
digits.data,
digits.target,
test_size=0.25,
random_state=42,
stratify=digits.target,
)
model = RandomForestClassifier(n_estimators=300, random_state=42)
model.fit(X_train, y_train)
predictions = model.predict(X_test)
The starter contains no generative-adversarial model: there is no generator, discriminator, DCGAN architecture, loss terms, or sampling pipeline. Instead it trains a RandomForest classifier on the digits dataset, so it does not generate images or evaluate generation metrics like FID.
Proposed extension: train a small DCGAN on a curated subset (for example, a minority class) to produce synthetic images for augmentation and then measure whether classifier performance improves on a balanced validation set.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
