A Validation Approach to Over-parameterized Matrix and Image Recovery
Lijun Ding, Zhen Qin, Liwei Jiang +2
This paper studies the problem of recovering a low-rank matrix from several noisy random linear measurements. We consider the setting where the rank of the ground-truth matrix is u…

Flat minima generalize for low-rank matrix recovery
Lijun Ding, Dmitriy Drusvyatskiy, Maryam Fazel +1
Empirical evidence suggests that for a variety of overparameterized nonlinear models, most notably in neural network training, the growth of the loss around a minimizer strongly im…

Algorithmic Regularization in Model-free Overparametrized Asymmetric Matrix Factorization
Liwei Jiang, Yudong Chen, Lijun Ding
We study the asymmetric matrix factorization problem under a natural nonconvex formulation with arbitrary overparametrization. The model-free setting is considered, with minimal as…
