The learning aspect of deep learning is:

a. is figuring out the weights of all parameters associated with all layers in a network such that it minimizes the loss function calculated based on predictions made by the last layer and the training dataset

b. None of the other

c. is figuring out the weights of all layers in a network such that it maximizes the output

d.is figuring out the weights of all layers in a network such that it minimizing the output layer
