## Log-sum-exp

### Why

Improves numerical stability.

### How

- usually chosen to be
- I can see that the introduction of will make it more stable, by
decreasing how much affects the sum, but at the same time you
will get even smaller exponentials due to . In my head that would
imply even more instability, no? I guess the constant somehow
provides more
*stability*than this additional instability..
