    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 :)

    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.
