Find a closed form solution for $$\underset{X}{\operatorname{argmin}} \|A−XB\|^2_F$$ where $\| \cdot \|_F$ denotes the Frobenius norm.
I have found this thread. Not sure if it helps here though. Any ideas? Do I just start analyzing the above given the Frobenius norm and then simply calculate the derivatives? Is there a better way to go?
