I realized a lot of people keep pursuing and learning Competitive Programming because they get addicted to Rankings & Ratings. In this blog i have tried to help you exploit your same existing mechanism and learn Machine Learning in the process while pursuing it a competitive way.
I have drawn examples from around 10 kaggle Competitions and illustrated what works and what doesn't , what is important and what is not and how much time usually it takes for each step while competing. I have also heavily linked through the blog post and it contains more than enough links for you to start competing on Kaggle or Analytics Vidhya seriously.
Also last event by Threads, Felicity'18 called "Kings of Machine Learning" is still live. There is Rs 15,000 cash prizes and 20 T-shirts up for the Grab. If you enjoyed participating in other threads events like Gordian Knot, Codecraft, Fools Programming then probably you will enjoy this too.
