Explicit for-loop optimisation or SupervisedTrainer

It seems that in the majority of tutorials, the optimisation for loop is given explicitly. In relatively few places, the SupervisedTrainer is used, despite existing for this reason.

I can see why having the explicit for loop is beneficial for tutorials - so that people are more aware of the inner workings. However, for the sake of conciseness, I would be in favour of having just one notebook (named suitably) in which the explicit for loop is given, and then from there on, using the SupervisedTrainer. Notebooks using SupervisedTrainer could then refer to the explicit notebook.

I think @ericspod is in favour of leaving the notebooks as they are, so as not to hide anything (which I understand). Anyone else have an opinion?

Esamina i notebook del tutorial che utilizzano cicli di ottimizzazione espliciti e SupervisedTrainer, quindi confrontane i ruoli didattici. Decidi se un notebook debba mantenere il ciclo esplicito e gli altri debbano farvi riferimento; il lavoro è completato quando l’insieme dei tutorial segue l’approccio coerente scelto.
