Addestramento integrato

Addestrare reti di Deep Learning per dati sequenziali e tabellari utilizzando le funzioni di addestramento integrate

Dopo aver definito l'architettura della rete, è possibile definire i parametri di addestramento utilizzando la funzione trainingOptions. È quindi possibile addestrare la rete utilizzando la funzione trainnet. Utilizzare la rete addestrata per prevedere le etichette delle classi o le risposte numeriche, nonché per prevedere i passi temporali futuri.

È possibile addestrare una rete neurale su una CPU, una GPU, più CPU o GPU, oppure in parallelo su un cluster o nel cloud. L'addestramento su GPU o in parallelo richiede Parallel Computing Toolbox™. L’utilizzo di una GPU richiede un dispositivo GPU supportato (per informazioni sui dispositivi supportati, vedere GPU Computing Requirements (Parallel Computing Toolbox)). Specificare l’ambiente di esecuzione utilizzando la funzione trainingOptions.
