Can someone please explain how this works to a software engineer who used to work with heuristically observable functions and algorithms? I'm having a hard time comprehending how a mix of experts can work.

In SE, to me, it would look like (sorting example):

- Having 8 functions that do some stuff in parallel

- There's 1 function that picks the output of a function that (let's say) did the fastest sorting calculation and takes the result further

But how does that work in ML? How can you mix and match what seems like simple matrix transformations in a way that resembles if/else flowchart logic?
