What is exploding gradient problem?

Updated May 16, 2026

Short answer

Exploding gradient occurs when gradients become excessively large during training.

Deep explanation

When gradients grow exponentially during backpropagation, parameter updates become unstable and training diverges. It often occurs in deep or recurrent networks.

Real-world example

RNN training becoming numerically unstable.

Common mistakes

  • Ignoring gradient clipping techniques.

Follow-up questions

  • What is gradient clipping?
  • How is it different from vanishing gradient?
