Parameters: parameters ( Iterable[Tensor] or Tensor) – an iterable of Tensors or a … WebClipping by value is done by passing the `clipvalue` parameter and defining the value. In this case, gradients less than -0.5 will be capped to -0.5, and gradients above 0.5 will be capped to 0.5. The `clipnorm` gradient clipping can be applied similarly. In this case, 1 is specified.
