Understanding the exploding gradient problem

Why Neural Networks Explode — A Simple Fix That Helps

Training some neural networks, especially RNNs, can feel like steering a boat in storm, because small changes sometimes grow out of control and cause learning to fail.
This runaway behavior people call exploding gradients, it makes the model jump wildly and forget what it was learning.
The good news is there is a plain and useful trick: keep the big numbers in check.
That trick, known as gradient clipping, stops huge updates and lets training continue without blowing up.
It does not solve every problem, but brings back calm and better stability, so the network can focus on learning patterns.
You can think of it like a safety rope that limits how far a step can go, small change but huge effect.
Many teams use this simple rule, and often it was enough to get much better results on tasks like predicting text or music.
Try it when training feels unstable, you might surprised how often it helps, and training just runs smoother.
