## Riconoscimento delle immagini
Il machine learning viene utilizzato anche per il riconoscimento delle immagini.
La tipologia di rete neurale utilizzata per questa applicazione è chiamata rete neural a convoluzione ( **convolutional neural networks**), abbreviata CNN.
Innanzitutto consideriamo che ogni immagine può essere codificata come una matrice di valori

Una CNN esegue quattro step durante la fase di apprendimento
#### Convoluzione
Consideriamo l'immagine di un uccello.
