So, first off, I’m a touch thinker.  I can’t just read to learn much, I have to actually write code to figure out what’s happening.  My problem is I’ve figured out linear regression easily enough (it’s not terribly complicated using torch), but everything I read moves on immediately to computer vision, which I really don’t care about.  All I really want to do is figure out what’s really next after linear regression (I don’t know what question to ask in google).
Here’s what I want to do - instead of the basic y = 2x +1 problem, I want to add a second variable.  z = 2x * y, for example (I eventually want to build a model for 10 or more variables, but I need somewhere to start).
Can someone tell me what question to ask?  Is this RNN, DNN?  Log?  I just need a pointer or an example that doesn’t involve data loaders or CV.  Just raw numbers.
Appreciate any help I can get, thanks.
