Investigating the Impact of Quantization on Adversarial Robustness

no code implementations8 Apr 2024 Qun Li, Yuan Meng, Chen Tang, Jiacheng Jiang, Zhi Wang

Quantization is a promising technique for reducing the bit-width of deep models to improve their runtime performance and storage efficiency, and thus becomes a fundamental step for deployment.

Retraining-free Model Quantization via One-Shot Weight-Coupling Learning

no code implementations3 Jan 2024 Chen Tang, Yuan Meng, Jiacheng Jiang, Shuzhao Xie, Rongwei Lu, Xinzhu Ma, Zhi Wang, Wenwu Zhu

Conversely, mixed-precision quantization (MPQ) is advocated to compress the model effectively by allocating heterogeneous bit-width for layers.

Towards Fair and Comprehensive Comparisons for Image-Based 3D Object Detection

no code implementations ICCV 2023 Xinzhu Ma, Yongtao Wang, Yinmin Zhang, Zhiyi Xia, Yuan Meng, Zhihui Wang, Haojie Li, Wanli Ouyang

In this work, we build a modular-designed codebase, formulate strong training recipes, design an error diagnosis toolbox, and discuss current methods for image-based 3D object detection.

RGAT: A Deeper Look into Syntactic Dependency Information for Coreference Resolution

1 code implementation10 Sep 2023 Yuan Meng, Xuhao Pan, Jun Chang, Yue Wang

Our experiments on a public Gendered Ambiguous Pronouns (GAP) dataset show that with the supervision learning of the syntactic dependency graph and without fine-tuning the entire BERT, we increased the F1-score of the previous best model (RGCN-with-BERT) from 80. 3% to 82. 5%, compared to the F1-score by single BERT embeddings from 78. 5% to 82. 5%.

DIVA: A Dirichlet Process Mixtures Based Incremental Deep Clustering Algorithm via Variational Auto-Encoder

1 code implementation23 May 2023 Zhenshan Bing, Yuan Meng, Yuqi Yun, Hang Su, Xiaojie Su, Kai Huang, Alois Knoll

Generative model-based deep clustering frameworks excel in classifying complex data, but are limited in handling dynamic and complex features because they require prior knowledge of the number of clusters.

DNG: Taxonomy Expansion by Exploring the Intrinsic Directed Structure on Non-gaussian Space

1 code implementation22 Feb 2023 Songlin Zhai, Weiqing Wang, YuanFang Li, Yuan Meng

Specifically, the inherited feature originates from "parent" nodes and is weighted by an inheritance factor.

SEAM: Searching Transferable Mixed-Precision Quantization Policy through Large Margin Regularization

no code implementations14 Feb 2023 Chen Tang, Kai Ouyang, Zenghao Chai, Yunpeng Bai, Yuan Meng, Zhi Wang, Wenwu Zhu

This general and dataset-independent property makes us search for the MPQ policy over a rather small-scale proxy dataset and then the policy can be directly used to quantize the model trained on a large-scale dataset.

Estimating Granger Causality with Unobserved Confounders via Deep Latent-Variable Recurrent Neural Network

no code implementations9 Sep 2019 Yuan Meng

We use a generative model with latent variable to build the relationship between the unobserved confounders and the observed variables(tested variable and the proxy variables).
