A Survey on Self-Supervised Pre-Training of Graph Foundation Models: A Knowledge-Based Perspective

1 code implementation24 Mar 2024 Ziwen Zhao, Yuhua Li, Yixiong Zou, Ruixuan Li, Rui Zhang

Graph self-supervised learning is now a go-to method for pre-training graph foundation models, including graph neural networks, graph transformers, and more recent large language model (LLM)-based graph models.

Flatten Long-Range Loss Landscapes for Cross-Domain Few-Shot Learning

no code implementations1 Mar 2024 Yixiong Zou, Yicong Liu, Yiman Hu, Yuhua Li, Ruixuan Li

To enhance the transferability and facilitate fine-tuning, we introduce a simple yet effective approach to achieve long-range flattening of the minima in the loss landscape.

Masked Graph Autoencoder with Non-discrete Bandwidths

1 code implementation6 Feb 2024 Ziwen Zhao, Yuhua Li, Yixiong Zou, Jiliang Tang, Ruixuan Li

Inspired by these understandings, we explore non-discrete edge masks, which are sampled from a continuous and dispersive probability distribution instead of the discrete Bernoulli distribution.

Decoupling Representation and Knowledge for Few-Shot Intent Classification and Slot Filling

no code implementations21 Dec 2023 Jie Han, Yixiong Zou, Haozhao Wang, Jun Wang, Wei Liu, Yao Wu, Tao Zhang, Ruixuan Li

Therefore, current works first train a model on source domains with sufficiently labeled data, and then transfer the model to target domains where only rarely labeled data is available.

ECEA: Extensible Co-Existing Attention for Few-Shot Object Detection

no code implementations15 Sep 2023 Zhimeng Xin, Tianxu Wu, Shiming Chen, Yixiong Zou, Ling Shao, Xinge You

Extensive experiments on the PASCAL VOC and COCO datasets show that our ECEA module can assist the few-shot detector to completely predict the object despite some regions failing to appear in the training samples and achieve the new state of the art compared with existing FSOD methods.

Decoupled Rationalization with Asymmetric Learning Rates: A Flexible Lipschitz Restraint

1 code implementation23 May 2023 Wei Liu, Jun Wang, Haozhao Wang, Ruixuan Li, Yang Qiu, Yuankai Zhang, Jie Han, Yixiong Zou

However, such a cooperative game may incur the degeneration problem where the predictor overfits to the uninformative pieces generated by a not yet well-trained generator and in turn, leads the generator to converge to a sub-optimal model that tends to select senseless pieces.

CSGCL: Community-Strength-Enhanced Graph Contrastive Learning

1 code implementation8 May 2023 Han Chen, Ziwen Zhao, Yuhua Li, Yixiong Zou, Ruixuan Li, Rui Zhang

Graph Contrastive Learning (GCL) is an effective way to learn generalized graph representations in a self-supervised manner, and has grown rapidly in recent years.

Margin-Based Few-Shot Class-Incremental Learning with Class-Level Overfitting Mitigation

1 code implementation10 Oct 2022 Yixiong Zou, Shanghang Zhang, Yuhua Li, Ruixuan Li

Few-shot class-incremental learning (FSCIL) is designed to incrementally recognize novel classes with only few training samples after the (pre-)training on base classes with sufficient samples, which focuses on both base-class performance and novel-class generalization.

Annotation Efficient Person Re-Identification with Diverse Cluster-Based Pair Selection

no code implementations10 Mar 2022 Lantian Xue, Yixiong Zou, Peixi Peng, Yonghong Tian, Tiejun Huang

To solve this problem, we propose the Annotation Efficient Person Re-Identification method to select image pairs from an alternative pair set according to the fallibility and diversity of pairs, and train the Re-ID model based on the annotation.

Annotation-Efficient Untrimmed Video Action Recognition

no code implementations30 Nov 2020 Yixiong Zou, Shanghang Zhang, Guangyao Chen, Yonghong Tian, Kurt Keutzer, José M. F. Moura

In this paper, we target a new problem, Annotation-Efficient Video Recognition, to reduce the requirement of annotations for both large amount of samples and the action location.

Revisiting Mid-Level Patterns for Cross-Domain Few-Shot Recognition

no code implementations7 Aug 2020 Yixiong Zou, Shanghang Zhang, JianPeng Yu, Yonghong Tian, José M. F. Moura

To solve this problem, cross-domain FSL (CDFSL) is proposed very recently to transfer knowledge from general-domain base classes to special-domain novel classes.

Compositional Few-Shot Recognition with Primitive Discovery and Enhancing

no code implementations12 May 2020 Yixiong Zou, Shanghang Zhang, Ke Chen, Yonghong Tian, Yao-Wei Wang, José M. F. Moura

Inspired by such capability of humans, to imitate humans' ability of learning visual primitives and composing primitives to recognize novel classes, we propose an approach to FSL to learn a feature representation composed of important primitives, which is jointly trained with two parts, i. e. primitive discovery and primitive enhancing.

ODN: Opening the Deep Network for Open-set Action Recognition

no code implementations23 Jan 2019 Yu Shu, Yemin Shi, Yao-Wei Wang, Yixiong Zou, Qingsheng Yuan, Yonghong Tian

Most of the existing action recognition works hold the \textit{closed-set} assumption that all action categories are known beforehand while deep networks can be well trained for these categories.
