WebNov 30, 2024 · The problem we're trying to solve by gradient clipping is that of exploding gradients: Let's assume that your RNN layer is computed like this: h_t = sigmoid (U * x + W * h_tm1 + b) So forgetting about the nonlinearity for a while, you could say that a current state h_t depends on some earlier state h_ {t-T} as h_t = W^T * h_tmT + input. WebJun 18, 2024 · Gradient Clipping Another popular technique to mitigate the exploding gradients problem is to clip the gradients during backpropagation so that they never exceed some threshold. This is called Gradient Clipping. This optimizer will clip every component of the gradient vector to a value between –1.0 and 1.0.
