Learning Rate

A numerical value which controls how much the gradients update the parameters of a model.

---

The learning rate controls how much the gradients adjust the parameters by multiplying the learning rate and gradients together.

Note

A learning rate that is too high can cause the training system to either get stuck in a loop or diverge from the optimal weights.

A learning rate that is too low can cause the training system to take a very long time to reach the optimal weights.
