+We can implemented different algorithms from similarity matching famility by specifying different $\Phi, \Psi$, and constraints on $Y$, $W$, and $M$.
 For example:
 
 When $W,M,Y$ are unbounded, and $$\Phi(W) = \frac{1}{2}\text{Tr}WW^{\top}, \text{  and  } \Psi(M) = \frac{1}{2}\text{Tr}MM^{\top},$$
