torchrl.objectives.symexp

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

Apply the inverse of symlog() element-wise.

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 symexp, symlog
>>> x = torch.tensor([-1000.0, 0.0, 1000.0])
>>> torch.allclose(symexp(symlog(x)), x, atol=1e-4)
True
