Said Achmiz comments on How fast can we perform a forward pass?

[Said Achmiz]

If you edit the post on GreaterWrong, you should be able to paste in the LaTeX source and have it render, e.g.:

$\text{ElapsedTime}=\{\begin{array}{cc}\frac{54C^2}{M^3}& :\text{if}B>\frac{2}{3}M\sqrt{N}\\ \frac{8C^{2}N}{B^2(M-B/\sqrt{N})}& :\text{else.}\end{array}$

(I don’t know how to do it in the Less Wrong editor, but presumably it’s possible there as well.)
