I had gone through some of the data science tutorials but none of them teach how to choose the modelling

In my experience, it is a question of practicing. There are also cases where some approaches are more recommended than others. In that case it is better to follow what the majority of researchers do.

In case there are several approaches to tackle one thing, and let's say you are using supervised models, then there are techniques for model comparison.

Hope this helps.

Is anyone familiar with Big O?

Hi @BananaCire what is exactly your problem with Big O?

@arunkumar413 I'd recommend this book if you're able to find it It is a very applied book (as the title suggests) and it will go over the modeling process in choosing the right model and optimizing it. I've only gotten through a little bit of it but it is a good start.
@arunkumar413 but I agree with @evaristoc. It does come with practice as well, especially when it comes to applying these models to a certain problem.
