Here, wxyp(D4)??[Math. 28]
is a weight held in the neural network.
Lastly, an activation layer 1205 performs a non-linear process on the v value and outputs an O value as a determination result. This process is similar to that by the activation layer 605.
In the above embodiment, a method of obtaining an estimated image by using a single neural network has been described. According to the present embodiment, the amount of operation for the learning is reduced.
