Preparing for the MTech in AI at IISc: Cutoff, Subjects, and Tips

As of my last knowledge update in August 2023, the cutoff for admission to the MTech in Artificial Intelligence (AI) program at the Indian Institute of Science (IISc) can vary each year based on factors such as the number of applicants, their performance, and the overall demand for the program. Generally, a strong score in the Graduate Aptitude Test in Engineering (GATE) is essential, with cutoffs typically ranging from around 600 to 800 in the relevant papers, depending on the year.

What's the Cutoff for MTech in AI at IISc?

The cutoff for the MTech in AI program at IISc can fluctuate annually. It is influenced by the number of applicants, their performance, and the demand for the program. Historically, a GATE score in the range of 600 to 800 in the relevant papers has been needed for admission. However, it is always advisable to regularly check the official IISc website for the most accurate and up-to-date information.

Subjects to Focus On for a Better Interview

To prepare effectively for an interview for the MTech in AI at IISc, consider focusing on the following subjects:

Mathematics

Linear Algebra Probability and Statistics Calculus Optimization Techniques

Computer Science Fundamentals

Data Structures and Algorithms Complexity Theory Operating Systems Computer Networks

Miscellaneous Fields

Supervised and Unsupervised Learning Neural Networks and Deep Learning Natural Language Processing Reinforcement Learning

Programming Skills

Proficiency in languages like Python, R, or Java Familiarity with libraries such as TensorFlow, PyTorch, NumPy, and Pandas

Additionally, be prepared to discuss any relevant projects or research you have done in AI or related fields, and stay updated on recent advancements in AI such as developments in generative models, ethical AI, and applications in various domains.

Choosing a Subject: Tips and Considerations

When it comes to choosing a subject, candidates frequently opt for Linear Algebra (LA), Probability, or Algorithms. However, choosing a harder topic than these can result in exponentially harder questions. For example, what you might think you know about Markov Chains may not be enough for a professor's level of understanding. Therefore, it's essential to be aware that the questions may be much more advanced than what you initially thought.

These topics are also often chosen for comprehensive exams for PhDs at IISc after two years, so the questions are likely to be from the same domain but much easier. Here are some tips for each subject:

Preparation for Linear Algebra (LA)

Be prepared to prove things, even simple ones. Watch online videos by Prof. Gilbert Strang but don't rely solely on his book. Consider reading Linear Algebra Done Right by Sheldon Axler for advanced topics. Practice proving that row rank equals column rank, even if you don't solve it completely, demonstrating a solid approach.

Preparation for Probability

While I didn't prepare this part extensively, it's highly recommended given the challenges faced during the interview. Questions may not involve specific distributions, so a good understanding of the basics is sufficient.

A highly recommended book is An Introduction to Probability Theory and Its Applications by William Feller. Online videos by Niladri from IITD on NPTEL are also a great resource.

Preparation for Algorithms

For Computer Science (CS) students, having a good preparation is essential. You should be able to explain things clearly, not just know the algorithms. Commonly referred books include Introduction to Algorithms by Cormen, Leiserson, Rivest, and Stein (CLRS) and Algorithm Design by Jon Kleinberg and éva Tardos. However, Algorithm Design by Tardos is better. Implement algorithms from a book like Algorithms by Robert Sedgewick in your preferred language to gain a better grip on programming, beyond theoretical knowledge tested by GATE. Further, you need to know about running times and complexity.

Preparation Tips

The following tips can help you prepare for the interview effectively:

Mock Interviews

Practice with peers or mentors to simulate the interview experience.

Problem-Solving

Engage in coding challenges and problems related to algorithms and data structures to hone your skills.

Research IISc

Understand the faculty’s research interests and align your preparation with them.

Focusing on these areas will help you demonstrate your knowledge and passion for AI during the interview. Being thoroughly prepared will not only increase your chances of success but also contribute positively to your enthusiasm and readiness for the rigorous program at IISc.
