Generative AI Interview Questions
Here is a comprehensive list of questions and answers on Generative AI that you should know before your next interview.
Questions on Basic Concepts
Q1. What is generative AI?
Answer: Generative AI refers to artificial intelligence that can create new content, such as text, graphics, music, and movies. It works by analyzing existing content to identify patterns and connections before using that knowledge to generate original material.
Q2. How do Generative Adversarial Networks (GANs) work?
Answer: GANs are a subset of generative AI that generate new data through a unique two-network architecture. One network, the Generator, creates new data, while the other network, the Discriminator, evaluates the authenticity of the generated data.
Q3. What are the main components of a GAN?
Answer: A GAN consists of two primary neural networks – the Generator, which creates new data, and the Discriminator, which evaluates the authenticity of the generated data. These networks compete with each other in an iterative process to improve their performance.
Q4. Can you explain the difference between discriminative and generative models?
Answer: Discriminative models predict or categorize data based on existing information, while generative models understand the underlying structure of the data and can create new samples that are similar to the training data.
Q5. What is latent space in generative models?
Answer: Latent space is a compressed, hidden layer that captures the essence of the training data in generative AI models. It allows the model to navigate and generate new data based on the patterns learned from the training data.
Questions on Practical Applications of Generative AI
Q6. How is generative AI used in healthcare?
Answer: Generative AI has various applications in healthcare, including drug discovery, diagnostics, personalized medicine, and medical research. It can help in creating new drug candidates, enhancing diagnostics, and generating synthetic patient data for research.
