Improving Faithfulness for Vision Transformers

no code implementations29 Nov 2023 Lijie Hu, Yixin Liu, Ninghao Liu, Mengdi Huai, Lichao Sun, Di Wang

However, ViTs suffer from issues with explanation faithfulness, as their focal points are fragile to adversarial attacks and can be easily changed with even slight perturbations on the input image.

Fair Text-to-Image Diffusion via Fair Mapping

no code implementations29 Nov 2023 Jia Li, Lijie Hu, Jingfeng Zhang, Tianhang Zheng, Hua Zhang, Di Wang

In this paper, we address the limitations of existing text-to-image diffusion models in generating demographically fair results when given human-related descriptions.

Differentially Private Natural Language Models: Recent Advances and Future Directions

no code implementations22 Jan 2023 Lijie Hu, Ivan Habernal, Lei Shen, Di Wang

In this paper, we provide the first systematic review of recent advances in DP deep learning models in NLP.

SEAT: Stable and Explainable Attention

no code implementations23 Nov 2022 Lijie Hu, Yixin Liu, Ninghao Liu, Mengdi Huai, Lichao Sun, Di Wang

Results show that SEAT is more stable against different perturbations and randomness while also keeps the explainability of attention, which indicates it is a more faithful explanation.

Faster Rates of Private Stochastic Convex Optimization

no code implementations31 Jul 2021 Jinyan Su, Lijie Hu, Di Wang

Specifically, we first show that under some mild assumptions on the loss functions, there is an algorithm whose output could achieve an upper bound of $\tilde{O}((\frac{1}{\sqrt{n}}+\frac{\sqrt{d\log \frac{1}{\delta}}}{n\epsilon})^\frac{\theta}{\theta-1})$ for $(\epsilon, \delta)$-DP when $\theta\geq 2$, here $n$ is the sample size and $d$ is the dimension of the space.

High Dimensional Differentially Private Stochastic Optimization with Heavy-tailed Data

no code implementations23 Jul 2021 Lijie Hu, Shuo Ni, Hanshen Xiao, Di Wang

To better understand the challenges arising from irregular data distribution, in this paper we provide the first study on the problem of DP-SCO with heavy-tailed data in the high dimensional space.

Differentially Private (Gradient) Expectation Maximization Algorithm with Statistical Guarantees

no code implementations22 Oct 2020 Di Wang, Jiahao Ding, Lijie Hu, Zejun Xie, Miao Pan, Jinhui Xu

To address this issue, we propose in this paper the first DP version of (Gradient) EM algorithm with statistical guarantees.

Estimating Smooth GLM in Non-interactive Local Differential Privacy Model with Public Unlabeled Data

no code implementations1 Oct 2019 Di Wang, Lijie Hu, Huanyu Zhang, Marco Gaboardi, Jinhui Xu

In the second part of the paper, we extend our idea to the problem of estimating non-linear regressions and show similar results as in GLMs for both multivariate Gaussian and sub-Gaussian cases.
