I have been an avid learner of statistics and machine learning. The primary reason for exploring them has been the ability to apply them to use-cases cutting across different domains and problems. This included problems across auction, pricing, survival analysis and so on.
I have had the opportunity to explore healthcare, trading and sports analytics in the form of cricket. Over the years, the effort has been to be able to solve problems end to end which means, taking a problem statement, preparing the data pipelines and finally putting the model into production.

Consistently, I would often end up re-using similar problem-solving approaches. Likewise often wanted to remember all the cool tricks/hacks and hard-learned concepts I have had been able to work-out all these years.
And several other contests during campus days !!
Besides improving your odds of winning these, I decided to write some notes to help collate concepts. Also takeaways from ML in an intuitive fashion. If you are one of those guys who love diagrams and moreover intuition over maths to better understand stuff, you would love them.
