Macros explanation

Papad

Hi everybody,
Can anyone give me a simple explanation of macros meaning and way that we use them?
Thanks in advance.

Hi @Papad

Here is one simple use case. Imagine you have a process which trains and validates a model on a certain dataset. It has various operators, each of them has different settings. You can use SET MACROS operator to define values of your most important parameters (for example, validation settings, model settings etc), so each time you need to change a certain parameter you don't need to go thru the whole process and open corresponding operators parameters, but you can control these parameters in a single place (SET MACROS operator). In some sense, you are controlling hyperparameters this way. 

Hope this sounds clear

I've already watched this, but I couldn't fully understand it. I would appreciate it if you could give me a simple explanation of it's meaning and it's use.
Thanks in advance.

Hi @Papad ,

what of the video did you not understand?

Best,

What I understand is that typically we set a different name and we can make changes by using it. But I've got the feeling that this is just a very simple explanation and I can do more things with macros that I don't understand.
