Why a computer science professor makes cheat sheets
I am Avishek Nag, an Associate Professor of Computer Science. I teach and research computer science, and my work centres on optimisation, telecommunications and AI.
Every semester I see the same pattern. Students rarely struggle because the ideas are too hard. They struggle because the essentials are scattered across lecture slides and a dozen browser tabs. The night before an exam or a job interview, nobody needs another 400-page book. They need the right page.
That is what this shop sells. Each cheat sheet, template and toolkit condenses something I teach, research, or write about into a few pages you can print or keep open on a tablet. The maths behind machine learning. The numbers every system design answer needs. A thesis template that compiles on Overleaf the first time. A grant proposal structure that an evaluator can follow.
Akribeia is the Greek word for precision. I chose the name because it is the standard I hold every page to. The notation must be correct, and every diagram must make one point clearly.
Some products grew out of my books, including Maths for AI, Maths for LLM and The Tradeoff Method. Others come from years of reviewing theses, papers and funding proposals.
A note on honesty. A cheat sheet will not replace working through problems yourself. It shows you what matters and where to look. I use AI tools to help with drafting and layout, and I check every formula, figure and page myself before it goes into the shop.
If something is unclear or a file does not open, send me a message. I read every one and fix problems within 48 hours.
Thank you for stopping by.
