DreamTuner: Single Image is Enough for Subject-Driven Generation

no code implementations21 Dec 2023 Miao Hua, Jiawei Liu, Fei Ding, Wei Liu, Jie Wu, Qian He

Diffusion-based models have demonstrated impressive capabilities for text-to-image generation and are expected for personalized applications of subject-driven generation, which require the generation of customized concepts with one or a few reference images.

Contrastive Representation Disentanglement for Clustering

no code implementations8 Jun 2023 Fei Ding, Dan Zhang, Yin Yang, Venkat Krovi, Feng Luo

We conduct a theoretical analysis of the proposed loss and highlight how it assigns different weights to negative samples during the process of disentangling the feature representation.

XMP-Font: Self-Supervised Cross-Modality Pre-training for Few-Shot Font Generation

no code implementations CVPR 2022 Wei Liu, Fangyue Liu, Fei Ding, Qian He, Zili Yi

The cross-modality encoder is pre-trained in a self-supervised manner to allow effective capture of cross- and intra-modality correlations, which facilitates the content-style disentanglement and modeling style representations of all scales (stroke-level, component-level and character-level).

Decoupled IoU Regression for Object Detection

no code implementations2 Feb 2022 Yan Gao, Qimeng Wang, Xu Tang, Haochen Wang, Fei Ding, Jing Li, Yao Hu

Prior works propose to predict Intersection-over-Union (IoU) between bounding boxes and corresponding ground-truths to improve NMS, while accurately predicting IoU is still a challenging problem.

Multi-level Knowledge Distillation via Knowledge Alignment and Correlation

1 code implementation1 Dec 2020 Fei Ding, Yin Yang, Hongxin Hu, Venkat Krovi, Feng Luo

While it is important to transfer the full knowledge from teacher to student, we introduce the Multi-level Knowledge Distillation (MLKD) by effectively considering both knowledge alignment and correlation.

Hierarchical Attention Networks for Medical Image Segmentation

no code implementations20 Nov 2019 Fei Ding, Gang Yang, Jinlu Liu, Jun Wu, Dayong Ding, Jie Xv, Gangwei Cheng, Xirong Li

Unlike previous self-attention based methods that capture context information from one level, we reformulate the self-attention mechanism from the view of the high-order graph and propose a novel method, namely Hierarchical Attention Network (HANet), to address the problem of medical image segmentation.

Double cycle-consistent generative adversarial network for unsupervised conditional generation

no code implementations13 Nov 2019 Fei Ding, Feng Luo, Yin Yang

We enforce the encoder and the generator of GAN to form an encoder-generator pair in addition to the generator-encoder pair, which enables us to avoid the low-diversity generation and the triviality of latent features.
