By the way, i want to konw why does the equation 7 in paper use e^x not just use x for the difinition? in this way the complexity of 3DNA is (hws)(h+w+s)
这里的HWS是范围吧,那e的HWS次方不是早就超出attention的范围了?
Indeed, this is a weird statement. By rewriting the product of exponential factors as a single exponential of the variable x=h+w+s
:
(e^h)(e^w)(e^s) = e^(h+w+s)
We are on a classical inequality between x
and e^x
, and it is easy to prove or verify that x < e^x
for every x
.
yeah,so how it would be x > e^x. (h+w+s)> e^h e^w e^s. like the paper said.
As the paper says in appendix: "For example, for long videos or high-resolution frames with large h, w, s, usually (e^h)(e^w)(e^s)< (h + w + s)" Is there any situation that (e^h)(e^w)(e*s)< (h + w + s)?
