Adaptive Skeleton Graph Decoding

no code implementations19 Feb 2024 Shuowei Jin, Yongji Wu, Haizhong Zheng, Qingzhao Zhang, Matthew Lentz, Z. Morley Mao, Atul Prakash, Feng Qian, Danyang Zhuo

Large language models (LLMs) have seen significant adoption for natural language tasks, owing their success to massive numbers of model parameters (e. g., 70B+); however, LLM inference incurs significant computation and memory costs.

Learn To be Efficient: Build Structured Sparsity in Large Language Models

no code implementations9 Feb 2024 Haizhong Zheng, Xiaoyan Bai, Beidi Chen, Fan Lai, Atul Prakash

The emergence of activation sparsity in LLMs provides a natural approach to reduce this cost by involving only parts of the parameters for inference.

Leveraging Hierarchical Feature Sharing for Efficient Dataset Condensation

no code implementations11 Oct 2023 Haizhong Zheng, Jiachen Sun, Shutong Wu, Bhavya Kailkhura, Zhuoqing Mao, Chaowei Xiao, Atul Prakash

In this paper, we recognize that images share common features in a hierarchical way due to the inherent hierarchical structure of the classification system, which is overlooked by current data parameterization methods.

Coverage-centric Coreset Selection for High Pruning Rates

1 code implementation28 Oct 2022 Haizhong Zheng, Rui Liu, Fan Lai, Atul Prakash

We then propose a novel one-shot coreset selection method, Coverage-centric Coreset Selection (CCS), that jointly considers overall data coverage upon a distribution as well as the importance of each example.

Understanding and Diagnosing Vulnerability under Adversarial Attacks

no code implementations17 Jul 2020 Haizhong Zheng, Ziqi Zhang, Honglak Lee, Atul Prakash

Moreover, we design the first diagnostic method to quantify the vulnerability contributed by each layer, which can be used to identify vulnerable parts of model architectures.

Efficient Adversarial Training with Transferable Adversarial Examples

2 code implementations CVPR 2020 Haizhong Zheng, Ziqi Zhang, Juncheng Gu, Honglak Lee, Atul Prakash

Adversarial training is an effective defense method to protect classification models against adversarial attacks.

Analyzing the Interpretability Robustness of Self-Explaining Models

no code implementations27 May 2019 Haizhong Zheng, Earlence Fernandes, Atul Prakash

Recently, interpretable models called self-explaining models (SEMs) have been proposed with the goal of providing interpretability robustness.

Robust Classification using Robust Feature Augmentation

no code implementations26 May 2019 Kevin Eykholt, Swati Gupta, Atul Prakash, Amir Rahmati, Pratik Vaishnavi, Haizhong Zheng

Existing deep neural networks, say for image classification, have been shown to be vulnerable to adversarial images that can cause a DNN misclassification, without any perceptible change to an image.
