About us

One Fourth Labs is a startup incubated at the IIT Madras Research Park by faculty members. We believe that AI is a disruptive technology. We are committed to readying India for the AI-age with affordable high-quality online courses, and building solutions with societal and commercial value.

PadhAI is our education arm. The word PadhAI can be read in many ways, each meaningful. In Hindi it can mean studies (पढ़ाई) or study AI (पढ़ AI). In Tamil you can read it as path (பாதை). Lets together read and understand AI and build the path forward.

A First Course on Deep Learning

Our flagship offering is a 5-month online course on Deep Learning. It provides both basic theoretical understanding and practical hands-on programming. It is beginner-friendly, but builds up expertise sufficiently to work with state-of-the-practice methods. 

We began the first batch in Feb 1, 2019 and received a very large response. The next batch begins on Aug 1, 2019. Registrations will begin on Jul 10, 2019. If you are interested, you can join the waitlist for the course.

Praveen R

This course is the best as it focuses both on the theory and hands on.This course introduced me to Kaggle competitions and I got addicted to it. I feel more confident that I can contribute to real world projects involving deep learning after taking this course.

Tulasi Ram Laghumavarapu

Never seen a course like this which has a perfect balance between theory and hands-on


Padhai is one among the best place to learn. The courses offered by Padhai is cheap, very effective and worth spending time on. I would love to take up more courses in Padhai.

Vudata Rohit

Learned a lot from this course. Before starting this course, I have no knowledge of deep learning but after learning this course I am pretty confident.

Deepak Kumar G S

Highly recommended for deep learning beginners and pros alike.

Srivathsan Vijayaraghavan

I would suggest this course to all of my colleagues and students.

Kanumuri Sri Naga Sai Ajith

This course can turn you into a deep learning enthusiast if you have the urge to learn something new (even if you don't know anything about deep learning at all).

Shashank Mishra

There was paradigm shift in knowledge of deep Learning after pursuing this course.

Deepak Choudhary

It is best hands-on practical Deep learning course taught in a beautiful way.

Ari Ezhilarasan

Focussing more on fundamentals what makes this course so special. I could still imagine how I transitioned from an MP neuron to Encoder-Decoder architecture. Hats off to both the professors.

FAQ for students

  • What is the immediate next step?

    If you would like to enrol for the August 1st batch, you can join the waitlist. You will be notified when the registrations begin.

  • Are these courses offered by IIT Madras?

    No, these courses are not offered by IIT Madras. You will not get any certificate or course credits from IIT Madras. While we are affiliated with IIT Madras, this course is offered by our startup, One Fourth Labs.

  • How is this different from other courses?

    The focus of the courses is primarily on combining theoretical knowledge with hands-on experience. Further, the emphasis is to go from limited pre-requisites to solving a challenging problems. Finally, we hope to build a community around PadhAI by continuing to engage with you after the course through the DL garage, subsequent courses, and also through our startup One Fourth Labs which will build solutions on Deep Learning.

  • Will I get a certificate on completing a course?

    Yes, upon successful completion, you will get a certificate from our startup One Fourth Labs. This certificate will be accessible to you through LinkedIn so that you can add it to your profile.

  • Will I get compute resources for running assignments and for working on the project?

    No, we will not be able to provide compute resources. The hands-on sessions are run on Google Colaboratory which is free for use. This should be sufficient for most of the course. For specific hands-on exercises, you can use free tiers of AWS and GCP.

  • What are the pre-requisites?

    The primary pre-requisite is a working knowledge of Python. We do not expect you to be familiar with AI or related topics. Mathematical understanding equivalent to 12th standard syllabus would be sufficient. However, the course requires a time commitment of 4 hours per week.

  • How can I ask my doubts?

    We will have discussion forums where you can discuss the topics covered and ask doubts. Your peers or our TAs will answer the questions. Additionally, there will periodical video calls once a fortnight where instructors will answer questions.
