Non-unique games over compact groups and orientation estimation in cryo-EM

14 May 2015Afonso S. BandeiraYutong ChenAmit Singer

Let $\mathcal{G}$ be a compact group and let $f_{ij} \in L^2(\mathcal{G})$. We define the Non-Unique Games (NUG) problem as finding $g_1,\dots,g_n \in \mathcal{G}$ to minimize $\sum_{i,j=1}^n f_{ij} \left( g_i g_j^{-1}\right)$... (read more)
