A Probe Towards Understanding GAN and VAE Models
Lu Mi, Macheng Shen, Jingzhao Zhang
This project report compares some known GAN and VAE models proposed prior to 2017. There has been significant progress after we finished this report. We upload this report as an in…
R-SPIDER: A Fast Riemannian Stochastic Optimization Algorithm with Curvature Independent Rate
Jingzhao Zhang, Hongyi Zhang, Suvrit Sra
We study smooth stochastic optimization problems on Riemannian manifolds. Via adapting the recently proposed SPIDER algorithm \citep{fang2018spider} (a variance reduced stochastic…
Achieving Acceleration in Distributed Optimization via Direct Discretization of the Heavy-Ball ODE
Jingzhao Zhang, César A. Uribe, Aryan Mokhtari +1
We develop a distributed algorithm for convex Empirical Risk Minimization, the problem of minimizing large but finite sum of convex functions over networks. The proposed algorithm…
Missing links towards understanding equilibrium shapes of hexagonal boron nitride: algorithm, hydrogen passivation, and temperature effects
Jingzhao Zhang, Wenjing Zhao, Junyi Zhu
There is a large discrepancy between the experimental observations and the theoretical predictions in the morphology of hexagonal boron nitride (h-BN) nanosheets. Theoretically-pre…
Towards understanding the special stability of and
Sze-Chun Tsang, Jingzhao Zhang, Kinfai Tse +1
Reversible hydrogen incorporation was recently attested [N. Lu, , Nature , 124 (2017)] in , the brownmillerite phase (BM…
Stability of wurtzite semi-polar surfaces: algorithms and practices
Yiou Zhang, Jingzhao Zhang, Junyi Zhu
A complete knowledge of absolute surface energies with any arbitrary crystal orientation is important for the improvements of semiconductor devices because it determines the equili…
