Log-Sum-Exponential
The natural logarithm of the sum of the elementwise exponential, \log∑_{i=1}^n e^{x_i}.
log_sum_exp(x, axis = NA_real_, keepdims = FALSE)

(Optional) The dimension across which to apply the function: |

(Optional) Should dimensions be maintained when applying the atom along an axis? If |
An Expression representing the log-sum-exponential of the input.
