What is an AI Viva?

Before delving into the questions, it’s important to understand what an AI viva is. An AI viva (short for viva voce) is an oral examination that is often conducted as part of the evaluation for students pursuing advanced degrees in artificial intelligence or related fields. During the viva, the candidate is typically asked a series of questions by a panel of examiners to assess their understanding of their research, theoretical concepts, and practical applications of AI.

The AI viva typically takes place after the submission of a thesis or dissertation and can range from discussing general principles of AI to specific topics covered in the student’s research. This means that candidates need to be prepared to answer not only questions about their own work but also questions about broader AI topics.

Why Is It Important to Prepare for AI Viva Questions?

AI is a rapidly evolving field with complex concepts and diverse applications. As such, the examiners will expect you to demonstrate in-depth knowledge, critical thinking, and the ability to explain your work clearly. Here’s why thorough preparation is key:

1. Showcase Your Knowledge: The viva is a chance for you to demonstrate your mastery over the subject.
2. Answering Under Pressure: The oral nature of the exam can be stressful, so preparation helps you stay calm and composed.
3. Engage in Scientific Discourse: The viva allows for a discussion of your research in the context of the greater AI community.
4. Validate Your Work: A well-prepared candidate can confidently defend their thesis and provide solid justifications for their methods and conclusions.

Key Areas to Focus on During AI Viva Preparation

Before jumping into the list of potential AI viva questions, it’s important to categorize the areas you’ll need to study. Here are the key areas to focus on when preparing for an AI viva:

1. Theoretical Foundations of AI
   This includes basic concepts such as search algorithms, decision trees, neural networks, and reinforcement learning. You should also have a clear understanding of the different paradigms in AI, such as symbolic reasoning and machine learning.

2. Algorithms and Models
   Understanding the different algorithms used in AI is critical. You should be able to explain how algorithms like the A* algorithm, genetic algorithms, k-means clustering, and backpropagation work and when they are appropriate to use.

3. Machine Learning
   AI and machine learning go hand in hand, so be prepared for questions related to supervised learning, unsupervised learning, deep learning, and reinforcement learning. You should also be able to explain key concepts like overfitting, bias-variance tradeoff, and cross-validation.

4. Research and Literature Review
   Be ready to explain the context of your research and how it fits into the current body of knowledge. Familiarize yourself with recent developments in AI, especially in areas relevant to your thesis or dissertation.

5. Applications of AI
   Be prepared to discuss how AI is applied in different industries such as healthcare, finance, robotics, and natural language processing.

6. Ethical Considerations
   AI has significant ethical implications. Examiners may ask you about the ethical challenges associated with AI, such as bias in algorithms, privacy concerns, and the societal impact of automation.

Common AI Viva Questions

In this section, we’ll go through some of the most commonly asked AI viva questions. These questions will help you understand what to expect and will guide you on how to formulate your responses.

1. General AI and Theoretical Concepts

Question	Expected Response
What is artificial intelligence?	AI is the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions.
Can you explain the difference between AI and machine learning?	AI is a broader concept that refers to creating intelligent machines, whereas machine learning is a subset of AI focused on the development of algorithms that allow machines to learn from data.
What are the different types of AI?	AI can be categorized as Artificial Narrow Intelligence (ANI), Artificial General Intelligence (AGI), and Artificial Superintelligence (ASI).
What is the Turing Test?	The Turing Test, proposed by Alan Turing, assesses a machine’s ability to exhibit intelligent behavior indistinguishable from that of a human.

2. Machine Learning Algorithms

Question	Expected Response
What is supervised learning?	Supervised learning is a type of machine learning where the model is trained on labeled data, and the algorithm learns to make predictions based on this data.
Can you explain overfitting in machine learning?	Overfitting occurs when a model learns too much from the training data, including noise or random fluctuations, making it perform poorly on unseen data.
How does a decision tree algorithm work?	A decision tree splits the data into subsets based on the feature values, ultimately forming a tree-like structure that can be used for classification or regression.
What is the difference between bagging and boosting?	Bagging is an ensemble method where multiple models are trained independently, and boosting is an ensemble method where models are trained sequentially to correct the errors of previous models.

3. Neural Networks and Deep Learning

Question	Expected Response
What is backpropagation in neural networks?	Backpropagation is an algorithm used to minimize the error by adjusting the weights of a neural network during training through a process of gradient descent.
Explain the concept of a convolutional neural network (CNN).	CNNs are specialized neural networks designed for processing data with a grid-like topology, such as images, by using convolutional layers to detect features.
What is the vanishing gradient problem?	The vanishing gradient problem occurs when gradients used in backpropagation become very small, hindering the learning process, particularly in deep networks.

4. AI Ethics and Societal Impact

Question	Expected Response
What are some ethical concerns related to AI?	Ethical concerns in AI include bias in algorithms, job displacement due to automation, privacy issues, and the potential misuse of AI technologies.
How can AI bias be reduced?	AI bias can be mitigated by using diverse datasets, regular auditing of AI systems, and incorporating fairness constraints into algorithms.
Do you think AI will replace human jobs?	AI may replace some jobs, especially repetitive tasks, but it will also create new job opportunities in areas like AI development, maintenance, and supervision.

5. Future of AI and Research

Question	Expected Response
What do you see as the future of AI?	AI is expected to advance in areas like natural language processing, reinforcement learning, and human-robot interaction. It will continue to impact fields like healthcare, education, and business.
How do you ensure that your AI system is generalizable?	Generalizability can be achieved by using robust validation techniques, such as cross-validation, and testing the model on diverse datasets to ensure it works well across different scenarios.

Tips for Successfully Answering AI Viva Questions

Here are some tips for handling your AI viva effectively:

1. Understand the Basics: Even though you might be asked complex questions, examiners expect you to have a strong grasp of the foundational concepts.
2. Know Your Thesis Inside and Out: Be prepared to defend every aspect of your research and explain how your work fits into the broader AI landscape.
3. Stay Calm: Don’t panic if you don’t know the answer immediately. Take a deep breath, pause for a moment, and then respond logically.
4. Clarify Unclear Questions: If you don’t understand a question, it’s okay to ask for clarification rather than guess and give an incorrect answer.
5. Practice: Do mock vivas with peers or mentors to simulate the pressure of the oral exam and improve your responses.

Conclusion

Preparing for your AI viva can be an intense experience, but with the right approach, you can approach the exam with confidence. Review the most common AI viva questions, study key concepts, and be ready to engage in scientific discourse. Your viva is an opportunity to showcase your understanding of AI and to demonstrate your contribution to the field. With careful preparation, you’ll be well-equipped to answer AI viva questions effectively and impress your examiners.

Good luck!
