"""
Implements Adam algorithm weight decay fix.
Args:
params (list[Parameter]): A list of parameter, which will be updated. The element in `params`
should be class mindspore.Parameter.
learning_rate (Union[float, Tensor, Iterable]): A value for the learning rate. When the learning_rate is
Iterable or a Tensor and the dims of the Tensor is 1,
use dynamic learning rate, then the i-th step will
take the i-th value as the learning rate.
When the learning_rate is float or learning_rate is a Tensor
but the dims of the Tensor is 0, use fixed learning rate.
Other cases are not supported. Default: 1e-3.
beta1 (float): The exponential decay rate for the 1st moment estimates. Default: 0.9.
Should be in range (0.0, 1.0).
beta2 (float): The exponential decay rate for the 2nd moment estimates. Default: 0.999.
Should be in range (0.0, 1.0).
eps (float): Term added to the denominator to improve numerical stability. Default: 1e-6.
Should be greater than 0.
weight_decay (float): Weight decay (L2 penalty). Default: 0.0.
decay_filter (Function): A function to determine whether to apply weight decay on parameters. Default:
lambda x: 'LayerNorm' not in x.name and 'bias' not in x.name.
Inputs:
- **gradients** (tuple[Tensor]) - The gradients of `params`, the shape is the same as `params`,
and might be in sparse format.
Outputs:
tuple[Parameter], the updated velocity value, the shape is the same as `params`.
Examples:
>>> net = Net()

>>> optim = nn.AdamWeightDecay(params=net.trainable_params())
