Problem 8 - Entrance Test
Which statement about the vanishing gradient problem is true?
A. It only occurs in recurrent networks
B. It is caused by activation functions saturating at extremes
C. It increases the learning rate automatically
D. It speeds up convergence
Check Answer
Show Solution
Correct: B
When activation functions like sigmoid saturate (near 0 or 1), their gradients approach zero, causing gradients to shrink as they back-propagate.
