Low-Rank Tensor Estimation from Nonlinear Observations: A Unified Framework

Junren Chen, Lijun Ding, Dong Xia +1

We consider the estimation of a $d_{1} \times d_{2} \times d_{3}$ tensor $X^{⋆}$ of Tucker rank $(r_{1}, r_{2}, r_{3})$ from the nonlinear observations $\{y_i=f_i(\langle A_i,X^\star\rangle)\}_{…

On the Subsample Size of Quantile-Based Randomized Kaczmarz

Jian-Feng Cai, Junren Chen, Anna Ma +1

Quantile-based randomized Kaczmarz (QRK) was recently introduced to efficiently solve sparsely corrupted linear systems $A x^{*} + ε = b$ [SIAM J. Mat…
