Don't Waste Your Bits! Squeeze Activations and Gradients for Deep Neural Networks via TinyScript

no code implementations ICML 2020 Fangcheng Fu, Yuzheng Hu, Yihan He, Jiawei Jiang, Yingxia Shao, Ce Zhang, Bin Cui

Recent years have witnessed intensive research interests on training deep neural networks (DNNs) more efficiently by quantization-based compression methods, which facilitate DNNs training in two ways: (1) activations are quantized to shrink the memory consumption, and (2) gradients are quantized to decrease the communication cost.

HPL-ViT: A Unified Perception Framework for Heterogeneous Parallel LiDARs in V2V

no code implementations27 Sep 2023 Yuhang Liu, Boyi Sun, Yuke Li, Yuzheng Hu, Fei-Yue Wang

It uses a graph-attention Transformer to extract domain-specific features for each agent, coupled with a cross-attention mechanism for the final fusion.

Understanding the Impact of Adversarial Robustness on Accuracy Disparity

1 code implementation28 Nov 2022 Yuzheng Hu, Fan Wu, Hongyang Zhang, Han Zhao

More specifically, we demonstrate that while the constraint of adversarial robustness consistently degrades the standard accuracy in the balanced class setting, the class imbalance ratio plays a fundamentally different role in accuracy disparity compared to the Gaussian case, due to the heavy tail of the stable distribution.

Is Vertical Logistic Regression Privacy-Preserving? A Comprehensive Privacy Analysis and Beyond

no code implementations19 Jul 2022 Yuzheng Hu, Tianle Cai, Jinyong Shan, Shange Tang, Chaochao Cai, Ethan Song, Bo Li, Dawn Song

We provide a comprehensive and rigorous privacy analysis of VLR in a class of open-source Federated Learning frameworks, where the protocols might differ between one another, yet a procedure of obtaining local gradients is implicitly shared.

Actor-critic is implicitly biased towards high entropy optimal policies

no code implementations ICLR 2022 Yuzheng Hu, Ziwei Ji, Matus Telgarsky

We show that the simplest actor-critic method -- a linear softmax policy updated with TD through interaction with a linear MDP, but featuring no explicit regularization or exploration -- does not merely find an optimal policy, but moreover prefers high entropy optimal policies.

Towards Understanding the Data Dependency of Mixup-style Training

1 code implementation ICLR 2022 Muthu Chidambaram, Xiang Wang, Yuzheng Hu, Chenwei Wu, Rong Ge

Despite seeing very few true data points during training, models trained using Mixup seem to still minimize the original empirical risk and exhibit better generalization and robustness on various tasks when compared to standard training.

Second-order Information in First-order Optimization Methods

1 code implementation20 Dec 2019 Yuzheng Hu, Licong Lin, Shange Tang

To the best of our knowledge, this is the first paper that seriously considers the necessity of square root among all adaptive methods.
