Addestramento personalizzato utilizzando la differenziazione automatica
Se la funzione trainingOptions non fornisce le opzioni di addestramento necessarie per l'attività o se è presente una funzione di perdita non supportata dalla funzione trainnet, è possibile definire un loop di addestramento personalizzato. Per i modelli che non possono essere specificati come reti di livelli, è possibile definire il modello come funzione. Per saperne di più, vedere Custom Training Loops.
