Question about the closed-form solution

[Hugo-cell111]

Hi! In your paper the correction term of the pseudo labels is calculated by equation 8. But since every term in equation 7 is known, I wonder why we don't directly use the equation 7? Thanks!

Hi, Equ. 7 is just a recursive equation for a single iteration. It normally takes tens of iterations to coverage. Instead, I apply the close-form one (Equ. 8) to obtain the optimal value directly.
