M-EBM: Towards Understanding the Manifolds of Energy-Based Models

1 code implementation8 Mar 2023 Xiulong Yang, Shihao Ji

Despite its simplicity, M-EBM significantly improves unconditional EBMs in training stability and speed on a host of benchmark datasets, such as CIFAR10, CIFAR100, CelebA-HQ, and ImageNet 32x32.

APSNet: Attention Based Point Cloud Sampling

1 code implementation11 Oct 2022 Yang Ye, Xiulong Yang, Shihao Ji

Traditional task-agnostic sampling methods, such as farthest point sampling (FPS), do not consider downstream tasks when sampling point clouds, and thus non-informative points to the tasks are often sampled.

Towards Bridging the Performance Gaps of Joint Energy-based Models

1 code implementation CVPR 2023 Xiulong Yang, Qing Su, Shihao Ji

This question has recently been answered in the affirmative, introducing the field of Joint Energy-based Model (JEM), which achieves high classification accuracy and image generation quality simultaneously.

Your ViT is Secretly a Hybrid Discriminative-Generative Diffusion Model

1 code implementation16 Aug 2022 Xiulong Yang, Sheng-Min Shih, Yinlin Fu, Xiaoting Zhao, Shihao Ji

Diffusion Denoising Probability Models (DDPM) and Vision Transformer (ViT) have demonstrated significant progress in generative tasks and discriminative tasks, respectively, and thus far these models have largely been developed in their own domains.

A Hierarchical N-Gram Framework for Zero-Shot Link Prediction

1 code implementation16 Apr 2022 Mingchen Li, Junfan Chen, Samuel Mensah, Nikolaos Aletras, Xiulong Yang, Yang Ye

Thus, in this paper, we propose a Hierarchical N-Gram framework for Zero-Shot Link Prediction (HNZSLP), which considers the dependencies among character n-grams of the relation surface name for ZSLP.

JEM++: Improved Techniques for Training JEM

1 code implementation ICCV 2021 Xiulong Yang, Shihao Ji

1) We propose a proximal SGLD to generate samples in the proximity of samples from the previous step, which improves the stability.

Improving Text-to-Image Synthesis Using Contrastive Learning

1 code implementation6 Jul 2021 Hui Ye, Xiulong Yang, Martin Takac, Rajshekhar Sunderraman, Shihao Ji

To address this issue, we propose a contrastive learning approach to improve the quality and enhance the semantic consistency of synthetic images.

Generative Max-Mahalanobis Classifiers for Image Classification, Generation and More

1 code implementation1 Jan 2021 Xiulong Yang, Hui Ye, Yang Ye, Xiang Li, Shihao Ji

We show that our Generative MMC (GMMC) can be trained discriminatively, generatively, or jointly for image classification and generation.

Learning with Multiplicative Perturbations

1 code implementation4 Dec 2019 Xiulong Yang, Shihao Ji

In this paper, we propose xAT and xVAT, new adversarial training algorithms, that generate \textbf{multiplicative} perturbations to input examples for robust training of DNNs.
