“The best notes are the ones you wish you had written yourself. I've spent twenty years trying to write them — first for my students, and now for yours.”
“The best notes are the ones you wish you had written yourself. I've spent twenty years trying to write them — first for my students, and now for yours.”
Milan has been teaching mathematics for more than two decades — first to engineering undergraduates in Akola and Mumbai, then to working professionals at Great Learning, the Emirates Institute of Finance in Dubai, and Airtics Education in Sharjah. Somewhere along the way he realized that the hardest part of learning AI wasn't the math. It was the gap between the textbook's prose and the notebook a patient mentor would draw you when you got stuck.
These notes are that notebook. Every page is handwritten — not stylized after the fact, but actually written by hand, on paper, the way he has explained these ideas to students one-on-one for years.
Milan holds a PhD in Mathematics from Sant Gadge Baba Amravati University (2011), with a thesis on Almost Periodic Functions on Locally Compact Groups. Before his present role as Senior Faculty in Data Science & AI at Great Learning in Bengaluru, he spent nearly a decade at NMIMS MPSTME in Mumbai, where he taught everything from engineering mathematics to functional analysis and topology. Earlier appointments took him through mathematics departments across Maharashtra between 2002 and 2012.
In industry, he led ML teams at Climate Connect Digital (a ReNew Power subsidiary), building production systems for energy-sector forecasting. His research has produced 15+ peer-reviewed publications in topological data analysis, persistent homology, and multi-objective optimization. In 2023, his team placed 6th globally out of 1,168 teams in the African Biomass Challenge.
Every Epoch Notes note set is written with one specific reader in mind: the learner who's already sat through the lectures, already tried the tutorial, and is now looking for the one page that makes it click. The reader who wants the why as clearly as the how. The reader the night before the interview or the exam.
The format is deliberately un-optimized for SEO. There are no 5,000-word listicles here, no AI-generated chapters, no ghostwriters. What you get is a single person's attempt to distill what matters, written in his own hand, with his own diagrams, priced so a student can afford them.
