For an input image, the method uses the gradients of the loss with respect to the input image to create a new image that maximises the loss. This new image is called the adversarial image. This can be summarised using the … gato city propertyWeb3 Mar 2024 · Gradient Clipping. Gradient clipping is a technique that tackles exploding gradients. The idea of gradient clipping is very simple: If the gradient gets too large, we rescale it to keep it small. More precisely, if ‖g‖ ≥ c, then. g ↤ c · g/‖g‖ where c is a hyperparameter, g is the gradient, and ‖g‖ is the norm of g. daybed frame twin size
