Recovering Linear Causal Models with Latent Variables via Cholesky Factorization of Covariance Matrix
Yunfeng Cai, Xu Li, Minging Sun +1
Discovering the causal relationship via recovering the directed acyclic graph (DAG) structure from the observed data is a well-known challenging combinatorial problem. When there a…
Identification of Matrix Joint Block Diagonalization
Yunfeng Cai, Ping Li
Given a set of square matrices, the matrix blind joint block diagonalization problem (BJBDP) is to find a full column rank matrix such that $C_i=A…
Tensor Completion via Tensor Networks with a Tucker Wrapper
Yunfeng Cai, Ping Li
In recent years, low-rank tensor completion (LRTC) has received considerable attention due to its applications in image/video inpainting, hyperspectral data recovery, etc. With dif…
Solving the Robust Matrix Completion Problem via a System of Nonlinear Equations
Yunfeng Cai, Ping Li
We consider the problem of robust matrix completion, which aims to recover a low rank matrix and a sparse matrix from incomplete observations of their sum $M=L_*+S_*\in…
An Inverse-free Truncated Rayleigh-Ritz Method for Sparse Generalized Eigenvalue Problem
Yunfeng Cai, Ping Li
This paper considers the sparse generalized eigenvalue problem (SGEP), which aims to find the leading eigenvector with at most nonzero entries. SGEP naturally arises in many ap…
