Log-sum-exp mathematical notation

Log-sum-exp is a recurring research-paper notation family. Combines exponentials under a logarithm, appearing as a smooth maximum and as the normalization term for categorical logits.

Log-sum-exp: Combines exponentials under a logarithm, appearing as a smooth maximum and as the normalization term for categorical logits. Example: Shift logits before exponentiation to preserve the same value with better numerical range.
