Quantization
We’re trying to understand the solutions when minimizing $$L(\zz) = {1 \over 2 M^2} \|\XX^T \ZZ^2 \XX – \SS\|_F^2 + {\lambda \over 2 N}\|\zz – \bone\|_2^2.$$ We can write this as $$L(\zz) = {1 \over 2 M^2} \|\RR \zz^2 – \ss \|_2^2 + {\lambda \over 2 N}\|\zz – \bone\|_2^2,$$ where the $i$’th column of $\RR$…
