You want to build a convolutional neural network to distinguish between types of cars in images. Your friend Alice, a biologist, has been working on a network to classify wildlife, which she calls WildNet. She spent several weeks training that network, and made it accessible to you. What can you do with it?
A. Nothing, wildlife is not the same as cars.
B. I can't reuse any of the weights of any layer, but I can take inspiration from the architecture of WildNet.
C. I can freeze the last few layers, and then remove the early layers and replace it with my own re-learned layers. That way, I can make use of the generic features learned by WildNet.
D. I can freeze the early layers, and then remove the last layers and replace it with my own re-learned layers. That way, I can make use of the generic features learned by WildNet.

Consider the following PyTorch code:
class ThreeLayerNet (nn.Module):
def __init__():
super().__init__()
def forward(x):
x = nn.Linear(100, 10)(x)
x = nn.ReLU()(x)
x = nn.Linear(10, 200)(x)
x = nn.ReLU()(x)
x = nn.Linear(200, 1)(x)
return x
Suppose that inputs are 100-dimensional, and outputs are 1-dimensional. What will happen if we try to train this network?
A. There will be an error because we are re-using the variable x throughout the forward() method.
B. There will be an error because the second layer has more neurons than the first. The number of neurons must never increase from one layer to the next.
C. The model will not train properly. The performance will be the same at the beginning of the first epoch and at the end of the last epoch.
