SpeechGuard: Exploring the Adversarial Robustness of Multimodal Large Language Models

no code implementations14 May 2024 Raghuveer Peri, Sai Muralidhar Jayanthi, Srikanth Ronanki, Anshu Bhatia, Karel Mundnich, Saket Dingliwal, Nilaksh Das, Zejiang Hou, Goeric Huybrechts, Srikanth Vishnubhotla, Daniel Garcia-Romero, Sundararajan Srinivasan, Kyu J Han, Katrin Kirchhoff

Despite safety guardrails, experiments on jailbreaking demonstrate the vulnerability of SLMs to adversarial perturbations and transfer attacks, with average attack success rates of 90% and 10% respectively when evaluated on a dataset of carefully designed harmful questions spanning 12 different toxic categories.

MILAN: Masked Image Pretraining on Language Assisted Representation

1 code implementation11 Aug 2022 Zejiang Hou, Fei Sun, Yen-Kuang Chen, Yuan Xie, Sun-Yuan Kung

When the masked autoencoder is pretrained and finetuned on ImageNet-1K dataset with an input resolution of 224x224, MILAN achieves a top-1 accuracy of 85. 4% on ViT-Base, surpassing previous state-of-the-arts by 1%.

CHEX: CHannel EXploration for CNN Model Compression

1 code implementation CVPR 2022 Zejiang Hou, Minghai Qin, Fei Sun, Xiaolong Ma, Kun Yuan, Yi Xu, Yen-Kuang Chen, Rong Jin, Yuan Xie, Sun-Yuan Kung

However, conventional pruning methods have limitations in that: they are restricted to pruning process only, and they require a fully pre-trained large model.

Multi-Dimensional Model Compression of Vision Transformer

1 code implementation31 Dec 2021 Zejiang Hou, Sun-Yuan Kung

In contrast, we advocate a multi-dimensional ViT compression paradigm, and propose to harness the redundancy reduction from attention head, neuron and sequence dimensions jointly.

Few-shot Learning via Dependency Maximization and Instance Discriminant Analysis

no code implementations7 Sep 2021 Zejiang Hou, Sun-Yuan Kung

We study the few-shot learning (FSL) problem, where a model learns to recognize new objects with extremely few labeled training data per category.

Effective Model Sparsification by Scheduled Grow-and-Prune Methods

1 code implementation ICLR 2022 Xiaolong Ma, Minghai Qin, Fei Sun, Zejiang Hou, Kun Yuan, Yi Xu, Yanzhi Wang, Yen-Kuang Chen, Rong Jin, Yuan Xie

It addresses the shortcomings of the previous works by repeatedly growing a subset of layers to dense and then pruning them back to sparse after some training.

A Feature-map Discriminant Perspective for Pruning Deep Neural Networks

no code implementations28 May 2020 Zejiang Hou, Sun-Yuan Kung

Network pruning has become the de facto tool to accelerate deep neural networks for mobile and edge applications.

Scalable Kernel Learning via the Discriminant Information

no code implementations23 Sep 2019 Mert Al, Zejiang Hou, Sun-Yuan Kung

Kernel approximation methods create explicit, low-dimensional kernel feature maps to deal with the high computational and memory complexity of standard techniques.
