torch.logaddexp2

function logaddexp2(input: Tensor, other: Tensor, options?: BinaryOptions): Tensor

Computes log2(2^x + 2^y) element-wise in a numerically stable way.

\text{logaddexp2}(x, y) = \log_2(2^x + 2^y)

Parameters

Tensor– wise logaddexp2

const x = torch.tensor([1.0, 2.0, 3.0]);
const y = torch.tensor([2.0, 3.0, 4.0]);
torch.logaddexp2(x, y);  // numerically stable log2(2^x + 2^y)
