What math do you know? You can quickly get started with PyTorch but usually people employed as AI/ML engineers have a heavy math background.

That said, it’s nothing too crazy. Most of deep learning is just linear algebra and optimization. For general data science, statistics and probability should be your main focus in my opinion.

Right but that’s not how SQl executes unfortunately. You go to Starbucks then ask for what you need. SQL does a Cartesian product of all the tables you need, then filters with the ON clause. Only then can you “order” what you want in SELECT.

In standard SQL syntax you’re essentially asking for what you want at your house then driving to a Starbucks.

More readable but doesn’t follow the execution order at all.

Interesting, I’ve used both for years and have found R to be way more intuitive for data exploration and visualization. R looks different than most programming languages, but once it clicks it’s actually really nice.
