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…

SelectNet: Learning to Sample from the Wild for Imbalanced Data Training

Yunru Liu, Tingran Gao, Haizhao Yang

Supervised learning from training data with imbalanced class sizes, a commonly encountered scenario in real applications such as anomaly/fraud detection, has long been considered a…

Uniform-in-Time Weak Error Analysis for Stochastic Gradient Descent Algorithms via Diffusion Approximation

Yuanyuan Feng, Tingran Gao, Lei Li +2

Diffusion approximation provides weak approximation for stochastic gradient descent algorithms in a finite time horizon. In this paper, we introduce new tools motivated by the back…

Multi-Frequency Phase Synchronization

Tingran Gao, Zhizhen Zhao

We propose a novel formulation for phase synchronization -- the statistical problem of jointly estimating alignment angles from noisy pairwise comparisons -- as a nonconvex optimiz…

Wasserstein Soft Label Propagation on Hypergraphs: Algorithm and Generalization Error Bounds

Tingran Gao, Shahab Asoodeh, Yi Huang +1

Inspired by recent interests of developing machine learning and data mining algorithms on hypergraphs, we investigate in this paper the semi-supervised learning algorithm of propag…

Gaussian Process Landmarking for Three-Dimensional Geometric Morphometrics

Tingran Gao, Shahar Z. Kovalsky, Doug M. Boyer +1

We demonstrate applications of the Gaussian process-based landmarking algorithm proposed in [T. Gao, S.Z. Kovalsky, and I. Daubechies, SIAM Journal on Mathematics of Data Science (…
