PyTorch torch.logaddexp function
PyTorch torch reference manual
torch.logaddexpis a function in PyTorch used to compute log(exp(x) + exp(y)).
Function definition
torch.logaddexp(input, other)
Usage example
Example
import torch
# compute log(exp(x) + exp(y))
x = torch.tensor([1.0, 2.0])
y = torch.tensor([3.0, 4.0])
z = torch.logaddexp(x, y)
print("logaddexp:", z)
# compute log(exp(x) + exp(y))
x = torch.tensor([1.0, 2.0])
y = torch.tensor([3.0, 4.0])
z = torch.logaddexp(x, y)
print("logaddexp:", z)
The output is:
logaddexp: tensor([3.0486, 4.0181])
