Dr. Subhrajit Roy

Scientist by profession. Teacher at heart.

I am a Scientist at IBM Research - Australia, working with the TrueNorth team on Machine Learning and its applications to mobile processors. I completed my Ph.D. from the Nanyang Technological University, Singapore on Neural Networks and Deep Learning. Like most researchers, I juggle between performing research and teaching students. My research involves developing novel algorithms that will be applied to automatically program the IBM's revolutionary neural network computer i.e. the TrueNorth system. I have published over 20 papers in international journals and conferences and you can check out my most cited papers below.

On the other hand, I love to teach my students the things I work on. After getting excellent feedback from the students I teach at the local universities, I decided to cater to the huge online community. My motto is to teach Machine Learning in a simple way such that it does not seem difficult and becomes accessible to everyone. I believe that behind each successful Machine Learning algorithm there is a physical significance or intuition that makes it work. Mathematics is required only to validate it. This thought pushed me into the path of creating and publishing courses related to Machine Learning, Big Data and Neural Networks where I shall discover and share those intuitions with you.

Please don't hesitate to drop me a message if you have a suggestion for a topic for one of my courses, or need help with something. I would love to talk to you.
