Multi-Frequency Phase Synchronization

ICML 2019oral

We propose a novel formulation for phase synchronization—the statistical problem of jointly estimating alignment angles from noisy pairwise comparisons—as a nonconvex optimization problem that enforces consistency among the pairwise comparisons in multiple frequency channels. Inspired by harmonic re…

Unsupervised Co-Learning on $G$-Manifolds Across Irreducible Representations

Yifeng Fan, Tingran Gao, Zhizhen Jane Zhao

NeurIPS 2019poster

We introduce a novel co-learning paradigm for manifolds naturally admitting an action of a transformation group $\mathcal{G}$, motivated by recent developments on learning a manifold from attached fibre bundle structures. We utilize a representation theoretic mechanism that canonically associates mu…
