Suppose you are fitting a neural network with one hidden layer to a training set. You find that the cross validation error Jcv (0) is much larger than the training error Jtrain (0). Is increasing the number of hidden units likely to help? No, because it is currently suffering from high variance, so adding hidden units is unlikely to help. O b. Yes, because it is currently suffering from high bias. No, because it is currently suffering from high bias, so adding hidden units is unlikely to help. d. Yes, because this increases the number of parameters and lets the network represent more complex functions.

Question
Suppose you are fitting a neural network with one hidden layer to a training set. You
find that the cross validation error Jcy (0) is much larger than the training error
Jtrain(0). Is increasing the number of hidden units likely to help?
Oa.
No, because it is currently suffering from high variance, so adding hidden units is
unlikely to help.
Ob.
Yes, because it is currently suffering from high bias.
No, because it is currently suffering from high bias, so adding hidden units is unlikely
to help.
O d.
Yes, because this increases the number of parameters and lets the network
represent more complex functions.
