Ranking from Pairwise Comparisons in General Graphs and Graphs with Locality
Yanxi Chen
This technical report studies the problem of ranking from pairwise comparisons in the classical Bradley-Terry-Luce (BTL) model, with a focus on score estimation. For general graphs…
Fast Computation of Optimal Transport via Entropy-Regularized Extragradient Methods
Gen Li, Yanxi Chen, Yu Huang +3
Efficient computation of the optimal transport distance between two distributions serves as an algorithm subroutine that empowers various applications. This paper develops a scalab…
Learning Mixtures of Linear Dynamical Systems
Yanxi Chen, H. Vincent Poor
We study the problem of learning a mixture of multiple linear dynamical systems (LDSs) from unlabeled short sample trajectories, each generated by one of the LDS models. Despite th…
Learning Mixtures of Low-Rank Models
Yanxi Chen, Cong Ma, H. Vincent Poor +1
We study the problem of learning mixtures of low-rank models, i.e. reconstructing multiple low-rank matrices from unlabelled linear measurements of each. This problem enriches two…
Active Orthogonal Matching Pursuit for Sparse Subspace Clustering
Yanxi Chen, Gen Li, Yuantao Gu
Sparse Subspace Clustering (SSC) is a state-of-the-art method for clustering high-dimensional data points lying in a union of low-dimensional subspaces. However, while opt…
