Generative AI Interview Questions
Here’s our comprehensive list of questions and answers on Generative AI that you must know before your next interview.
Questions on Basic Concepts
Q1. What is generative AI?
Answer: Generative AI refers to artificial intelligence (AI) that can produce new content, including text, graphics, music, and even movies. It works like a really efficient copycat, finding connections and patterns in the existing content before using that knowledge to produce original stuff.
Here’s a breakdown of how it works:
- Training on Data: Large collections of preexisting data are used to train generative AI models. This might be an image collection for making new photographs, or it could be a dataset of text articles for authoring.
- Learning the Patterns: The model discovers the underlying linkages and patterns as it examines the data. For instance, it might pick up on the standard sentence pattern found in news stories or the way that paintings frequently blend various hues and shapes.
- Creating New Content: The model can begin creating new material as soon as it has a firm understanding of the patterns. It accomplishes this by leveraging its expertise to produce something that adheres to the same patterns as the data it was trained on, after receiving cues from a prompt or some initial information.
Q2. How do Generative Adversarial Networks (GANs) work?
Answer: Generative adversarial networks, or GANs, are a subset of generative artificial intelligence that generates fresh data through a unique two-network architecture. Consider it an art world version of a competition between a detective and a forger.
The two participants:
- Artist/Generator: This neural network produces fresh data, such as music or images. Using the training dataset, it takes random noise as a starting point and refines it to look like real data.
- Critic/Discriminator: This neural network examines input to identify if it is generated by the other network or real (from the training set).
The Adversarial Process:
To trick the discriminator, the generator continuously strives to produce ever-more-realistic data. In an attempt to become more proficient at identifying fakes, the discriminator examines both authentic data and the output of the generator.
The result is that the generator gradually gains the ability to provide data that can successfully fool the discriminator through this back-and-forth struggle. Then, this created data is regarded as practical and realistic.
Q3. What are the main components of a GAN?
Answer: Two primary neural networks that compete with one another make up a Generative Adversarial Network (GAN):
Generator (G): This network mimics the actions of a forger by continuously attempting to produce new data (text, audio, or images) that closely matches the authentic data from the training set. To create a new data sample, it begins with a random noise vector and modifies it through its layers. The generator’s ultimate objective is to trick the discriminator by gradually making its creations more and more like actual data.
Discriminator (D): Analyzing both created data from the generator and real data from the training set, this network functions as an art critic. Its task is to ascertain the veracity of a data sample. The discriminator is continuously educated to enhance its capacity to identify generator-created frauds.
This is how they collaborate:
- The generator generates fresh data and transmits it to the discriminator in an iterative process.
- After analyzing the data, the discriminator produces a classification (genuine or bogus).
- The generator modifies its internal parameters to enhance its forgeries in the subsequent round based on the discriminator’s feedback.
- In turn, the discriminator makes use of this updated bogus data to improve its forgery detection capabilities.
The ongoing competition between the discriminator and generator propels both networks forward. Both the generator and the discriminator improve in their ability to spot fakes and provide real data. The generator should be able to reliably generate data that fools the discriminator after a considerable amount of training, which suggests that the generated data is realistically convincing.

Q4. Can you explain the difference between discriminative and generative models?
Answer: Two core machine learning techniques that approach issues quite differently are discriminative and generative models. The following summarizes their main distinctions:
Goal
- Discriminative Model: Predicts or categorizes using data that is already available. It maps hidden data points to the most likely category by figuring out how an input (X) and an output (Y) relate to one another. (Consider: Deciding if an email is spam or not.)
- Generative Model: Generative model comprehends the data’s fundamental structure. It is able to produce completely new samples that are similar to the training data after learning the probability distribution of the data (P(X)). (Consider: Making a fresh picture that resembles a cat.)
Learning Process
- Discriminative Model: Learns the decision boundary that separates different classes in the data. It doesn’t necessarily need to understand how the data is created, just how to distinguish between categories. (Think: Drawing a line between dogs and cats in a picture)
- Generative Model: Learns the underlying rules and patterns that govern the data. It can then use this knowledge to create new data points that follow the same patterns. (Think: Learning the typical features of a cat, like whiskers, fur, and pointy ears)
Applications
- Discriminative model: We use discriminative models for image classification, spam filtering and sentiment analysis.
- Generative Model: Using generative models we can create new poems or articles, we can find anomalies and evencreate our own new music.
Analogy
- Discriminative Model: They are like a security guard who is trained or made to learn to identify authorized persons based on their badge, uniform, etc. (features). They do not need to know the making of badges, they just have to know how to spot them.
- Generative Model: They are like artists who study the human form and then use that knowledge to create realistic portraits of people they’ve never met.
Q5. What is latent space in generative models?
Answer: In generative AI, latent space is a crucial concept that underpins how these models create new data. It acts like a compressed, hidden layer that captures the essence of the training data. Here’s a breakdown:
Imagine this:
- You have a massive room filled with different types of shoes (training data).
- A generative model is like an artist who wants to create new, never-before-seen shoes based on the existing ones.
Latent space comes in here as a special room:
- This room doesn’t hold the actual shoes themselves, but rather a compressed representation of their key features.
- Each shoe in the original room is mapped to a specific point in this latent space.
- Points closer together in latent space represent shoes with more similarities (e.g., both running shoes), while distant points represent very different types of shoes (e.g., sandal vs. winter boot).
The magic happens here:
- The generative model can navigate this latent space.
- It can move around, sample points, and based on those points, generate entirely new shoes (data) that resemble the ones from the original room (training data).
Key properties of latent space:
- Lower dimensionality: Latent space is designed to be much lower dimensional than the original data. This compression allows for efficient manipulation and storage.
- Continuous: The points in latent space typically form a continuous space. This enables smooth transitions between generated data points.
- Learned: The specific structure and organization of the latent space are learned by the generative model during its training on the real data.
Benefits of latent space:
- Efficient data exploration: By navigating the latent space, the model can explore different variations within the data distribution, allowing for more diverse generation.
- Controllable generation: In some cases, researchers can manipulate specific dimensions of the latent space to influence the characteristics of the generated data.
- Data interpolation: By moving along a line between two points in latent space, the model can generate a sequence of data points that smoothly transition between the two original data examples.
Different generative models use latent space differently:
- Variational Autoencoders (VAEs): This type of autoencoding gives the user more control over the generated data because it explicitly models the latent space as a component of the design.
- Generative Adversarial Networks (GANs): Although GANs lack a specific latent space, one can understand the implicit latent space as the internal representations that are learned during training.

Q7. What is the role of transfer learning in generative AI?
Answer: As an efficiency enhancer and accelerator, transfer learning is essential to generative AI. Generative models, especially complicated ones, can require large amounts of data and substantial computer power to train. Transfer learning addresses these issues with a number of benefits, including:
- Faster Training: Generative AI models can use models that have already been trained on similar tasks. This pre-trained model can be used as a starting point since it already has broad information acquired from a sizable dataset. In contrast to beginning from scratch, the new model simply needs to be adjusted for the particular generative task, greatly cutting down on training time.
- Decreased Data Needs: Generative AI may be able to work well with smaller datasets by leveraging the information from a pre-trained model. This is especially useful for activities where it can be costly or time-consuming to obtain huge amounts of labeled data.
- Enhanced Performance: In certain cases, transfer learning can result in enhanced performance on the intended task. The new generative model may benefit from the pre-trained model’s ability to identify important underlying characteristics and correlations from a larger dataset.
Q8. What are some limitations of generative AI?
Answer: Despite its amazing potential, generative AI still has certain drawbacks that scientists are trying to solve. The following are some major obstacles:
1. Lack of True Creativity and Understanding
