looks like they meant “effective dense size” which is the square root of total params×active params, so in this case sqrt(397 x 17) = ~82

- zozbot234 7mo agoBut the claim that "one expert is 17B" is incorrect. Experts are picked with per-layer granularity (expert 1 for layer X may well be entirely unrelated to expert 1 for layer Y), and the individual layer-experts are tiny. The writeup for the original experiment is very clear on this.
- stingraycharles 7mo agoOk I am by no means an expert on this and I immediately stand corrected. But as I understand it, in order to understand the amount of active memory that’s required, it’s more accurate to go by the ~82B number, right?
- zozbot234 7mo agoThe ~82B figure is an attempt to compare performance to an equivalent dense model. The amount of active parameters is given by the ~17B.
