torchrl.objectives.symlog(x: Tensor) → Tensor

Apply the element-wise symmetric logarithm transform.

Parameters:

x (torch.Tensor) – Input tensor.

Returns:

A tensor with the same shape, dtype, and device as x.

Examples

>>> import torch
>>> from torchrl.objectives import symlog
>>> symlog(torch.tensor([-100.0, 0.0, 100.0]))
tensor([-4.6151,  0.0000,  4.6151])
