Deep Learning for Computer Vision Quiz 2 12 Apr 2026 — Question 13

Question 13

+1 markOne correct option

Vanishing gradients in vanilla RNNs are largely caused by:

  1. A

    The continuous addition of bias terms at each timestep which suppresses the gradient signal

  2. B

    Repeated multiplication by Jacobians whose spectral norm is often < 1

  3. C

    The use of unbounded activation functions like ReLU that cause activations to decay over time

  4. D

    The inability of the standard cross-entropy loss function to distinguish between short-term and long-term dependencies
