Figure 1:
A diagram of an artificial neural network.
1. (1 pt.)
How many hidden layers are in the neural network displayed in Figure 1?
3
2. (1 pt.)
How many total hidden units are in the neural network displayed in Figure 1?
9
3. (1 pt.)
How many hidden units are in the first hidden layer in the neural network displayed in
Figure 1? (Layers are counted from the bottom up.)
4
4. (2 pts.)
What is the type of neural network in Figure 1 typically called?
(Deep - optional) multilayer (1pt.) perceptron (1 pt.) or
(Deep - optional) feed forward (1 pt.) fully connected (1 pt.)
5. (1 pt.)
Artificial neural networks are typically the best type of models for pattern recognition in
images, but is this type of network in Figure 1 the
very best
type of network for pattern
recognition in images?
No - (optional: Deep Learning, i.e. CNN, is better for images)
6.
(1 pt.) True or False:

Section 05 Quiz
Figure 2:
A partial dependence plot for the variable
std_imp_rep_dti
, i.e. standardized
debt-to-income ratio, and some trained machine learning model.
7. (1 pt.)
In Figure 2, when
std_imp_rep_dti = -1
, what is the average prediction of the
trained model?
~ 0.175
8. (1 pt.) True or False:
In Figure 2, as
std_imp_rep_dti
increases the output of the model
tends to decrease.
False
9. (1 pt.) True or False:
In Figure 2, the learned behavior of
std_imp_rep_dti
with respect
to the model output appears to be basically linear.
True
