The formula for the logarithm of the sum of exponentials is:

The formula for the logarithm of the sum of exponentials is:

logSumExp(x) = log(sum(exp(x_i))) for i = 1 to n

This is computed in a numerically stable way by subtracting the maximum value in the array before taking the exponentials:

logSumExp(x) = max(x) + log(sum(exp(x_i - max(x)))) for i = 1 to n
