NTK-Guided Few-Shot Class Incremental Learning

no code implementations19 Mar 2024 Jingren Liu, Zhong Ji, Yanwei Pang, Yunlong Yu

While anti-amnesia FSCIL learners often excel in incremental sessions, they tend to prioritize mitigating knowledge attrition over harnessing the model's potential for knowledge acquisition.

SYNC-CLIP: Synthetic Data Make CLIP Generalize Better in Data-Limited Scenarios

1 code implementation6 Dec 2023 Mushui Liu, Weijie He, Ziqian Lu, Yunlong Yu

Prompt learning is a powerful technique for transferring Vision-Language Models (VLMs) such as CLIP to downstream tasks.

Dense Affinity Matching for Few-Shot Segmentation

no code implementations17 Jul 2023 Hao Chen, Yonghan Dong, Zheming Lu, Yunlong Yu, Yingming Li, Jungong Han, Zhongfei Zhang

Few-Shot Segmentation (FSS) aims to segment the novel class images with a few annotated samples.

MetaGait: Learning to Learn an Omni Sample Adaptive Representation for Gait Recognition

no code implementations6 Jun 2023 Huanzhang Dou, Pengyi Zhang, Wei Su, Yunlong Yu, Xi Li

Towards this goal, MetaGait injects meta-knowledge, which could guide the model to perceive sample-specific properties, into the calibration network of the attention mechanism to improve the adaptiveness from the omni-scale, omni-dimension, and omni-process perspectives.

DenseDINO: Boosting Dense Self-Supervised Learning with Token-Based Point-Level Consistency

no code implementations6 Jun 2023 Yike Yuan, Xinghe Fu, Yunlong Yu, Xi Li

In this paper, we propose a simple yet effective transformer framework for self-supervised learning called DenseDINO to learn dense visual representations.

Multi-Content Interaction Network for Few-Shot Segmentation

no code implementations11 Mar 2023 Hao Chen, Yunlong Yu, Yonghan Dong, Zheming Lu, Yingming Li, Zhongfei Zhang

Few-Shot Segmentation (FSS) is challenging for limited support images and large intra-class appearance discrepancies.

CODER: Coupled Diversity-Sensitive Momentum Contrastive Learning for Image-Text Retrieval

no code implementations21 Aug 2022 Haoran Wang, Dongliang He, Wenhao Wu, Boyang xia, Min Yang, Fu Li, Yunlong Yu, Zhong Ji, Errui Ding, Jingdong Wang

We introduce dynamic dictionaries for both modalities to enlarge the scale of image-text pairs, and diversity-sensitiveness is achieved by adaptive negative pair weighting.

Episode-based Prototype Generating Network for Zero-Shot Learning

1 code implementation CVPR 2020 Yunlong Yu, Zhong Ji, Zhongfei Zhang, Jungong Han

We introduce a simple yet effective episode-based training framework for zero-shot learning (ZSL), where the learning system requires to recognize unseen classes given only the corresponding class semantics.

A Semantics-Guided Class Imbalance Learning Model for Zero-Shot Classification

no code implementations26 Aug 2019 Zhong Ji, Xuejie Yu, Yunlong Yu, Yanwei Pang, Zhongfei Zhang

Towards alleviating the class imbalance issue in ZSC, we propose a sample-balanced training process to encourage all training classes to contribute equally to the learned model.

Stacked Semantics-Guided Attention Model for Fine-Grained Zero-Shot Learning

1 code implementation NeurIPS 2018 Yunlong Yu, Zhong Ji, Yanwei Fu, Jichang Guo, Yanwei Pang, Zhongfei (Mark) Zhang

Zero-Shot Learning (ZSL) is generally achieved via aligning the semantic relationships between the visual features and the corresponding class semantic descriptions.

Bi-Adversarial Auto-Encoder for Zero-Shot Learning

no code implementations20 Nov 2018 Yunlong Yu, Zhong Ji, Yanwei Pang, Jichang Guo, Zhongfei Zhang, Fei Wu

Existing generative Zero-Shot Learning (ZSL) methods only consider the unidirectional alignment from the class semantics to the visual features while ignoring the alignment from the visual features to the class semantics, which fails to construct the visual-semantic interactions well.

Stacked Semantic-Guided Attention Model for Fine-Grained Zero-Shot Learning

no code implementations21 May 2018 Yunlong Yu, Zhong Ji, Yanwei Fu, Jichang Guo, Yanwei Pang, Zhongfei Zhang

To this end, we propose a novel stacked semantics-guided attention (S2GA) model to obtain semantic relevant features by using individual class semantic features to progressively guide the visual features to generate an attention map for weighting the importance of different local regions.

Attribute-Guided Network for Cross-Modal Zero-Shot Hashing

no code implementations6 Feb 2018 Zhong Ji, Yuxin Sun, Yunlong Yu, Yanwei Pang, Jungong Han

To address the Cross-Modal Zero-Shot Hashing (CMZSH) retrieval task, we propose a novel Attribute-Guided Network (AgNet), which can perform not only IBIR, but also Text-Based Image Retrieval (TBIR).

Zero-Shot Learning via Latent Space Encoding

no code implementations26 Dec 2017 Yunlong Yu, Zhong Ji, Jichang Guo, Zhongfei, Zhang

Instead of requiring a projection function to transfer information across different modalities like most previous work, LSE per- forms the interactions of different modalities via a feature aware latent space, which is learned in an implicit way.

Transductive Zero-Shot Learning with a Self-training dictionary approach

no code implementations27 Mar 2017 Yunlong Yu, Zhong Ji, Xi Li, Jichang Guo, Zhongfei Zhang, Haibin Ling, Fei Wu

As an important and challenging problem in computer vision, zero-shot learning (ZSL) aims at automatically recognizing the instances from unseen object classes without training data.
