torch.logaddexp2¶

torch.logaddexp2(input, other, *, out=None) → Tensor¶

Logarithm of the sum of exponentiations of the inputs in base-2.

Calculates pointwise $\log_2\left(2^x + 2^y\right)$ . See torch.logaddexp() for more details.

Parameters

input (Tensor) – the input tensor.
other (Tensor) – the second input tensor

Keyword Arguments

out (Tensor, optional) – the output tensor.
