Define the target and data
Select a domain-specific image dataset and specify success criteria, such as an acceptable FID band and visual inspection protocol.
Generative adversarial networks. Assess sample fidelity.
Generative adversarial networks train a generator and a discriminator in opposition so the generator learns to produce realistic samples. Important practical issues include choosing an architecture, stabilising adversarial training (mode collapse, vanishing gradients), and using appropriate evaluation metrics such as FID and human preference studies.

Generative adversarial networks train a generator and a discriminator in opposition so the generator learns to produce realistic samples. Important practical issues include choosing an architecture, stabilising adversarial training (mode collapse, vanishing gradients), and using appropriate evaluation metrics such as FID and human preference studies.
A proposed application is to generate synthetic imagery for augmentation in low-data creative workflows, with a human reviewer validating outputs before any public use. This extension is not delivered by the supplied starter.
Select a domain-specific image dataset and specify success criteria, such as an acceptable FID band and visual inspection protocol.
Implement a simple generator and discriminator (for example DCGAN), and train with adversarial loss while logging losses and sample grids.
Compute FID and diversity scores, and perform human preference checks for artefacts, memorisation and identity leakage.
Add monitoring for drift and amplification of biases, and provide a human-in-the-loop approval step for publishing synthetic media.
The supplied starter defines a small set of 3-dimensional numeric examples, computes their centroid and covariance, then draws five multivariate-normal samples around that centroid and prints them. It uses only NumPy and does not implement any neural network, generator/discriminator pair, adversarial training loop or image data handling.
centroid = seed_examples.mean(axis=0)
covariance = np.cov(seed_examples.T) + np.eye(seed_examples.shape[1]) * 0.01
synthetic_samples = rng.multivariate_normal(centroid, covariance, size=5)
synthetic_samples = np.clip(synthetic_samples, 0, 1)
print(PROJECT_NAME)The starter draws Gaussian samples from a statistical centroid of five toy vectors and prints them. It is not a GAN: there is no generator or discriminator, no adversarial optimisation, and no image dataset; the outputs are low-dimensional numeric vectors and cannot validate generative-image performance.
A proposed extension is to replace the toy data with a small curated image dataset, implement a DCGAN or StyleGAN2-lite, log experiments (loss curves, sample grids), compute FID, and provide an interactive viewer for a human reviewer to flag problematic outputs.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
