Information Limits of Joint Community Detection and Finite Group Synchronization
Yifeng Fan, Zhizhen Zhao
The emerging problem of joint community detection and group synchronization, with applications in signal processing and machine learning, has been extensively studied in recent yea…
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…
End-to-end Alexa Device Arbitration
Jarred Barber, Yifeng Fan, Tao Zhang
We introduce a variant of the speaker localization problem, which we call device arbitration. In the device arbitration problem, a user utters a keyword that is detected by multipl…
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…
Multi-Frequency Vector Diffusion Maps
Yifeng Fan, Zhizhen Zhao
We introduce multi-frequency vector diffusion maps (MFVDM), a new framework for organizing and analyzing high dimensional datasets. The new method is a mathematical and algorithmic…
Unsupervised Co-Learning on -Manifolds Across Irreducible Representations
Yifeng Fan, Tingran Gao, Zhizhen Zhao
We introduce a novel co-learning paradigm for manifolds naturally equipped with a group action, motivated by recent developments on learning a manifold from attached fibre bundle s…
Representation Theoretic Patterns in Multi-Frequency Class Averaging for Three-Dimensional Cryo-Electron Microscopy
Yifeng Fan, Tingran Gao, Zhizhen Zhao
We develop in this paper a novel intrinsic classification algorithm -- multi-frequency class averaging (MFCA) -- for classifying noisy projection images obtained from three-dimensi…
Cryo-Electron Microscopy Image Analysis Using Multi-Frequency Vector Diffusion Maps
Yifeng Fan, Zhizhen Zhao
Cryo-electron microscopy (EM) single particle reconstruction is an entirely general technique for 3D structure determination of macromolecular complexes. However, because the image…
