Try these 3 questions from this book:
Q1. How accurate will the discriminator be for GAN models at the global optimum?
1. 1
2. 0.5
3. p_data/(p_g + p_data)
4. None of those
Answer: 0.5 As the generator improves with training, the discriminator performance gets worse because the discriminator can’t easily tell the difference between real and fake. If the generator succeeds perfectly, then the discriminator has a 50% accuracy. In effect, the discriminator flips a coin to make its prediction.
Q2. What are some of the use cases where Cycle GAN is preferred?
Answer: Cycle GAN is mostly utilized in situations when getting paired training samples is challenging. CycleGAN has a number of intriguing uses, such as photo enhancing, season transfer, transforming genuine photos into beautiful images, and more.
Q3. Why GANs are called implicit density models?
Answer: The training set’s data points are used to produce new data points by the generator network. The generator implicitly learns the distribution of the training set in order to create a new data point, and then creates the new data point based on this implicitly learnt distribution.
GANs are frequently referred to as the implicit density model since the generator network implicitly learns the distribution of the training set.

If you’re preparing for a job interview as a Machine Learning Engineer focusing on Generative Adversarial Networks (GANs), here are some common interview questions and detailed answers to help you ace the interview:
1. What are GANs and how do they work?
Answer: GANs are a type of neural network architecture used in unsupervised machine learning. They consist of two networks – a generator and a discriminator. The generator generates fake data samples, while the discriminator tries to distinguish between real and fake samples. The two networks are trained in a competitive manner, with the generator trying to improve its samples to fool the discriminator, and the discriminator trying to become better at distinguishing real from fake samples.
2. What are some common applications of GANs?
Answer: GANs have a wide range of applications, including image generation, image-to-image translation, style transfer, text-to-image generation, and more. They are also used in anomaly detection, data augmentation, and generating synthetic data for training machine learning models.
3. How do you evaluate the performance of a GAN?
Answer: The performance of a GAN can be evaluated using metrics such as the Inception Score, Frechet Inception Distance (FID), Precision and Recall, and Visual Turing Test. These metrics help assess the quality, diversity, and realism of the generated samples.
4. What are some common challenges in training GANs?
Answer: Some common challenges in training GANs include mode collapse, where the generator only generates a limited set of samples, vanishing gradients, instability in training, and hyperparameter tuning. Addressing these challenges often requires careful architecture design, training strategies, and regularization techniques.
5. How do you prevent mode collapse in GANs?
Answer: Mode collapse can be prevented by using techniques such as mini-batch discrimination, feature matching, label smoothing, and spectral normalization. These techniques help encourage the generator to produce diverse samples and prevent it from focusing on a limited set of modes.
6. Can you explain the concept of Wasserstein GAN (WGAN)?
Answer: WGAN is a variant of GANs that uses the Wasserstein distance (or Earth Mover’s distance) as the loss function. This helps overcome some of the challenges in training traditional GANs, such as mode collapse and instability. WGAN introduces a more stable training process and better convergence properties compared to traditional GANs.
By preparing for these interview questions and understanding the concepts behind GANs, you’ll be better equipped to showcase your knowledge and skills as a Machine Learning Engineer specializing in GANs. Good luck with your interview!
