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…
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…
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…
Top- ranking with a monotone adversary
Yuepeng Yang, Antares Chen, Lorenzo Orecchia +1
In this paper, we address the top- ranking problem with a monotone adversary. We consider the scenario where a comparison graph is randomly generated and the adversary is allowe…
