Bias-Corrected Subspace Intersection: Minimax-Optimal Shared Subspace Estimation in Multi-View Data

Xianwen Song, Yuepeng Yang, Cong Ma

Estimating a low-dimensional subspace shared across noisy data matrices is a fundamental problem in multi-view matrix estimation. We study this problem under the two-view JIVE mode…

Sample-efficient inductive matrix completion with noise and inexact side-information

Yuepeng Yang, Cong Ma

Inductive matrix completion (IMC) is a variant of low-rank matrix completion that incorporates row and column side-information. In principle, it can reduce the effective dimension…

When Are Trade-Off Functions Testable from Finite Samples?

Kaining Shi, Qiaosen Wang, Cong Ma

We study finite-sample inference for the trade-off function of two unknown probability distributions, the function that traces the optimal type I/type II error frontier in binary t…

Estimating shared subspace with AJIVE: the power and limitation of multiple data matrices

Yuepeng Yang, Cong Ma

Integrative data analysis often requires disentangling joint and individual variations across multiple datasets, a challenge commonly addressed by the Joint and Individual Variatio…

Random pairing MLE for estimation of item parameters in Rasch model

Yuepeng Yang, Cong Ma

The Rasch model, a classical model in the item response theory, is widely used in psychometrics to model the relationship between individuals' latent traits and their binary respon…
