A Spectral Method for Joint Community Detection and Orthogonal Group Synchronization
Yifeng Fan, Yuehaw Khoo, Zhizhen Zhao
Community detection and orthogonal group synchronization are both fundamental problems with a variety of important applications in science and engineering. In this work, we conside…
Scalable semidefinite programming approach to variational embedding for quantum many-body problems
Yuehaw Khoo, Michael Lindsey
In quantum embedding theories, a quantum many-body system is divided into localized clusters of sites which are treated with an accurate `high-level' theory and glued together self…
Committor functions via tensor networks
Yian Chen, Jeremy Hoskins, Yuehaw Khoo +1
We propose a novel approach for computing committor functions, which describe transitions of a stochastic process between metastable states. The committor function satisfies a back…
Joint Community Detection and Rotational Synchronization via Semidefinite Programming
Yifeng Fan, Yuehaw Khoo, Zhizhen Zhao
In the presence of heterogeneous data, where randomly rotated objects fall into multiple underlying categories, it is challenging to simultaneously classify them into clusters and…
