RMGN: A Regional Mask Guided Network for Parser-free Virtual Try-on

2 code implementations24 Apr 2022 Chao Lin, Zhao Li, Sheng Zhou, Shichang Hu, Jialun Zhang, Linhao Luo, Jiarun Zhang, Longtao Huang, Yuan He

Virtual try-on(VTON) aims at fitting target clothes to reference person images, which is widely adopted in e-commerce. Existing VTON approaches can be narrowly categorized into Parser-Based(PB) and Parser-Free(PF) by whether relying on the parser information to mask the persons' clothes and synthesize try-on images.

Preconditioned Gradient Descent for Over-Parameterized Nonconvex Matrix Factorization

no code implementations NeurIPS 2021 Jialun Zhang, Salar Fattahi, Richard Zhang

This over-parameterized regime of matrix factorization significantly slows down the convergence of local search algorithms, from a linear rate with $r=r^{\star}$ to a sublinear rate when $r>r^{\star}$.

Cost-Oriented Load Forecasting

How many samples is a good initial point worth in Low-rank Matrix Recovery?

no code implementations NeurIPS 2020 Jialun Zhang, Richard Zhang

Optimizing the threshold over regions of the landscape, we see that, for initial points not too close to the ground truth, a linear improvement in the quality of the initial guess amounts to a constant factor improvement in the sample complexity.
