Deep Polarization Reconstruction With PDAVIS Events

1 code implementation CVPR 2023 Haiyang Mei, Zuowen Wang, Xin Yang, Xiaopeng Wei, Tobi Delbruck

The polarization event camera PDAVIS is a novel bio-inspired neuromorphic vision sensor that reports both conventional polarization frames and asynchronous, continuously per-pixel polarization brightness changes (polarization events) with fast temporal resolution and large dynamic range.

Exploiting Spatial Sparsity for Event Cameras with Visual Transformers

no code implementations10 Feb 2022 Zuowen Wang, Yuhuang Hu, Shih-Chii Liu

The input to the ViT consists of events that are accumulated into time bins and spatially separated into non-overlapping sub-regions called patches.

GRUBERT: A GRU-Based Method to Fuse BERT Hidden Layers for Twitter Sentiment Analysis

2 code implementations Asian Chapter of the Association for Computational Linguistics 2020 Leo Horne, Matthias Matti, Pouya Pourjafar, Zuowen Wang

In this work, we introduce a GRU-based architecture called GRUBERT that learns to map the different BERT hidden layers to fused embeddings with the aim of achieving high accuracy on the Twitter sentiment analysis task.

Understanding (Non-)Robust Feature Disentanglement and the Relationship Between Low- and High-Dimensional Adversarial Attacks

1 code implementation4 Apr 2020 Zuowen Wang, Leo Horne

Recent work has put forth the hypothesis that adversarial vulnerabilities in neural networks are due to them overusing "non-robust features" inherent in the training data.

Invariance-inducing regularization using worst-case transformations suffices to boost accuracy and spatial robustness

no code implementations NeurIPS 2019 Fanny Yang, Zuowen Wang, Christina Heinze-Deml

This work provides theoretical and empirical evidence that invariance-inducing regularizers can increase predictive accuracy for worst-case spatial transformations (spatial robustness).
