Rethinking ResNets: Improved Stacking Strategies With High Order Schemes

no code implementations28 Mar 2021 Zhengbo Luo, Zitang Sun, Weilian Zhou, Zizhang Wu, Sei-ichiro Kamata

We show that the widely used DNN design strategy, constantly stacking a small design (usually 2-3 layers), could be easily improved, supported by solid theoretical knowledge and with no extra parameters needed.

Multivariate Density Estimation with Missing Data

1 code implementation14 Aug 2018 Zhen Li, Lili Wu, Weilian Zhou, Sujit Ghosh

Multivariate density estimation is a popular technique in statistics with wide applications including regression models allowing for heteroskedasticity in conditional variances.


Learning Gaussian Graphical Models Using Discriminated Hub Graphical Lasso

no code implementations17 May 2017 Zhen Li, Jingtian Bai, Weilian Zhou

When no hubs are known, we use Graphical Lasso (GL) to provide information of hubs and find that the performance of DHGL will always be better than HGL if correct prior information is given and will seldom degenerate when the prior information is wrong.
