Local Maxima of the Entrywise Norm on the Orthogonal Group
Dian Jin
The paper classifies all local (and thus global) maximizers of the entrywise fourth-power norm on real orthogonal matrices, showing that only signed permutation matrices achieve th…
On the sensitivity of the subspace predictor to behavioral perturbations
Dian Jin, Jeremy Coulson
Behavioral systems define discrete-time LTI systems in terms of a set of trajectories, which forms a linear subspace. This subspace underlies the subspace predictor used in data-dr…
Cost-optimal Sequential Testing via Doubly Robust Q-learning
Doudou Zhou, Yiran Zhang, Dian Jin +3
Clinical decision-making often involves selecting tests that are costly, invasive, or time-consuming, motivating individualized, sequential strategies for what to measure and when…
One-shot Robust Federated Learning of Independent Component Analysis
Dian Jin, Xin Bing, Yuqian Zhang
This paper studies robust one-shot aggregation for distributed and federated Independent Component Analysis (ICA). In this setting, each client computes a local ICA estimator, whil…
Optimal vintage factor analysis with deflation varimax
Xin Bing, Xin He, Dian Jin +1
Vintage factor analysis is one important type of factor analysis that aims to first find a low-dimensional representation of the original data, and then to seek a rotation such tha…
Community Detection for Contextual-LSBM: Theoretical Limitations of Misclassification Rate and Efficient Algorithms
Dian Jin, Yuqian Zhang, Qiaosheng Zhang
The integration of network information and node attribute information has recently gained significant attention in the community detection literature. In this work, we consider com…
