Efficient Backpropagation with Variance-Controlled Adaptive Sampling

1 code implementation27 Feb 2024 Ziteng Wang, Jianfei Chen, Jun Zhu

On all the tasks, VCAS can preserve the original training loss trajectory and validation accuracy with an up to 73. 87% FLOPs reduction of BP and 49. 58% FLOPs reduction of the whole training process.

Check and Link: Pairwise Lesion Correspondence Guides Mammogram Mass Detection

no code implementations13 Sep 2022 Ziwei Zhao, Dong Wang, Yihong Chen, Ziteng Wang, LiWei Wang

In mammogram mass detection, modeling pairwise lesion correspondence explicitly is particularly important.

Causality Inspired Representation Learning for Domain Generalization

1 code implementation CVPR 2022 Fangrui Lv, Jian Liang, Shuang Li, Bin Zang, Chi Harold Liu, Ziteng Wang, Di Liu

Specifically, we assume that each input is constructed from a mix of causal factors (whose relationship with the label is invariant across domains) and non-causal factors (category-independent), and only the former cause the classification judgments.

Rank-1 Constrained Multichannel Wiener Filter for Speech Recognition in Noisy Environments

1 code implementation1 Jul 2017 Ziteng Wang, Emmanuel Vincent, Romain Serizel, Yonghong Yan

Multichannel linear filters, such as the Multichannel Wiener Filter (MWF) and the Generalized Eigenvalue (GEV) beamformer are popular signal processing techniques which can improve speech recognition performance.

Fast Second Order Stochastic Backpropagation for Variational Inference

no code implementations NeurIPS 2015 Kai Fan, Ziteng Wang, Jeff Beck, James Kwok, Katherine A. Heller

We propose a second-order (Hessian or Hessian-free) based optimization method for variational inference inspired by Gaussian backpropagation, and argue that quasi-Newton optimization can be developed as well.

Differentially Private Data Releasing for Smooth Queries with Synthetic Database Output

no code implementations6 Jan 2014 Chi Jin, Ziteng Wang, Junliang Huang, Yiqiao Zhong, Li-Wei Wang

We develop an $\epsilon$-differentially private mechanism for the class of $K$-smooth queries.

Efficient Algorithm for Privately Releasing Smooth Queries

no code implementations NeurIPS 2013 Ziteng Wang, Kai Fan, Jia-Qi Zhang, Li-Wei Wang

Outputting the summary runs in time $O(n^{1+\frac{d}{2d+K}})$, and the evaluation algorithm for answering a query runs in time $\tilde O (n^{\frac{d+2+\frac{2d}{K}}{2d+K}} )$.
