Embodied Adversarial Attack: A Dynamic Robust Physical Attack in Autonomous Driving

no code implementations15 Dec 2023 Yitong Sun, Yao Huang, Xingxing Wei

As physical adversarial attacks become extensively applied in unearthing the potential risk of security-critical scenarios, especially in autonomous driving, their vulnerability to environmental changes has also been brought to light.

DeepMetricEye: Metric Depth Estimation in Periocular VR Imagery

no code implementations13 Nov 2023 Yitong Sun, Zijian Zhou, Cyriel Diels, Ali Asadipour

Despite the enhanced realism and immersion provided by VR headsets, users frequently encounter adverse effects such as digital eye strain (DES), dry eye, and potential long-term visual impairment due to excessive eye stimulation from VR displays and pressure from the mask.

Unified Adversarial Patch for Visible-Infrared Cross-modal Attacks in the Physical World

1 code implementation27 Jul 2023 Xingxing Wei, Yao Huang, Yitong Sun, Jie Yu

We also demonstrate the effectiveness of our approach in physical-world scenarios under various settings, including different angles, distances, postures, and scenes for both visible and infrared sensors.

Unified Adversarial Patch for Cross-modal Attacks in the Physical World

1 code implementation ICCV 2023 Xingxing Wei, Yao Huang, Yitong Sun, Jie Yu

To show the potential risks under such scenes, we propose a unified adversarial patch to perform cross-modal physical attacks, i. e., fooling visible and infrared object detectors at the same time via a single patch.

Out-of-Distribution Detection with Class Ratio Estimation

no code implementations8 Jun 2022 Mingtian Zhang, Andi Zhang, Tim Z. Xiao, Yitong Sun, Steven McDonagh

In this work, we propose to unify density ratio based methods under a novel framework that builds energy-based models and employs differing base distributions.

Spread Flows for Manifold Modelling

no code implementations29 Sep 2021 Mingtian Zhang, Yitong Sun, Chen Zhang, Steven McDonagh

Flow-based models typically define a latent space with dimensionality identical to the observational space.

Layer-Parallel Training of Residual Networks with Auxiliary Variables

no code implementations NeurIPS Workshop DLDE 2021 Qi Sun, Hexin Dong, Zewei Chen, Weizhen Dian, Jiacheng Sun, Yitong Sun, Zhenguo Li, Bin Dong

Backpropagation algorithm is indispensable for training modern residual networks (ResNets) and usually tends to be time-consuming due to its inherent algorithmic lockings.

On the Latent Space of Flow-based Models

no code implementations1 Jan 2021 Mingtian Zhang, Yitong Sun, Steven McDonagh, Chen Zhang

Flow-based generative models typically define a latent space with dimensionality identical to the observational space.

Self-supervised Disentangled Representation Learning

no code implementations1 Jan 2021 Xiaojiang Yang, Yitong Sun, Junchi Yan

In our experiments, we find that even the data is only augmented along a few latent variables, more latent variables can be identified, and adding a small noise in data space can stabilize this outcome.

Identifying Informative Latent Variables Learned by GIN via Mutual Information

no code implementations1 Jan 2021 Chen Zhang, Yitong Sun, Mingtian Zhang

However, in this paper, we point out that the method taken by GIN for informative latent variables identification is not theoretically supported and can be disproved by experiments.

A Practical Layer-Parallel Training Algorithm for Residual Networks

no code implementations3 Sep 2020 Qi Sun, Hexin Dong, Zewei Chen, Weizhen Dian, Jiacheng Sun, Yitong Sun, Zhenguo Li, Bin Dong

Gradient-based algorithms for training ResNets typically require a forward pass of the input data, followed by back-propagating the objective gradient to update parameters, which are time-consuming for deep ResNets.

Towards Better Understanding of Disentangled Representations via Mutual Information

no code implementations25 Nov 2019 Xiaojiang Yang, Wendong Bi, Yitong Sun, Yu Cheng, Junchi Yan

Most existing works on disentangled representation learning are solely built upon an marginal independence assumption: all factors in disentangled representations should be statistically independent.

On the Approximation Properties of Random ReLU Features

1 code implementation10 Oct 2018 Yitong Sun, Anna Gilbert, Ambuj Tewari

We study the approximation properties of random ReLU features through their reproducing kernel Hilbert space (RKHS).

But How Does It Work in Theory? Linear SVM with Random Features

1 code implementation NeurIPS 2018 Yitong Sun, Anna Gilbert, Ambuj Tewari

We prove that, under low noise assumptions, the support vector machine with $N\ll m$ random features (RFSVM) can achieve the learning rate faster than $O(1/\sqrt{m})$ on a training set with $m$ samples when an optimized feature map is used.
