Another solution to the exploding gradient problem is to clip the gradient if it becomes too large or too small. We can update the training of the MLP to use gradient clipping by adding the “clipvalue” argument to the optimization algorithm configuration. For example, the code below clips ...
Specifically, the values of the error gradient are checked against a threshold value and clipped or set to that threshold value if the error gradient exceeds the threshold. To some extent, the exploding gradient problem can be mitigated by gradient clipping (thresholding the values of the gradient...
Gradient norm scaling entails modifying the derivatives of the loss function to have a specified vector norm when the gradient vector’s L2 vector norm (sum of squared values) exceeds a threshold value. For example, we may provide a norm of 1.0, which means that if the vector norm for a...

General solution: Gradient alleviation State of the art Zero centered gradient penalty A preprocessing of zero-averaging the gradient Limitation: The gradient can only be weakened to a certain extent, but can not prevent gradientexplosion 2. Zero centered gradient penalty with Linear interpolation ...
The model is basically a hyper-dimensional surface and you’re doing some gradient, which is defined by the differential quotient descending through a multi-dimensional vector space.” The amount of energy consumed by doing that is increasing rapidly. “If you look at the amount of energy taken...
