OvarNet: Towards Open-vocabulary Object Attribute Recognition

1 code implementation CVPR 2023 Keyan Chen, XiaoLong Jiang, Yao Hu, Xu Tang, Yan Gao, Jianqi Chen, Weidi Xie

In this paper, we consider the problem of simultaneously detecting objects and inferring their visual attributes in an image, even for those with no manual annotations provided at the training stage, resembling an open-vocabulary scenario.

 Ranked #1 on Open Vocabulary Attribute Detection on OVAD benchmark (using extra training data)

Continuous Remote Sensing Image Super-Resolution based on Context Interaction in Implicit Function Space

1 code implementation16 Feb 2023 Keyan Chen, Wenyuan Li, Sen Lei, Jianqi Chen, XiaoLong Jiang, Zhengxia Zou, Zhenwei Shi

Despite its fruitful applications in remote sensing, image super-resolution is troublesome to train and deploy as it handles different resolution magnifications with separate models.

Prototypical Information Bottlenecking and Disentangling for Multimodal Cancer Survival Prediction

1 code implementation3 Jan 2024 Yilan Zhang, Yingxue Xu, Jianqi Chen, Fengying Xie, Hao Chen

Despite advantages of multimodal learning for cancer survival prediction, massive redundancy in multimodal data prevents it from extracting discriminative and compact information: (1) An extensive amount of intra-modal task-unrelated information blurs discriminability, especially for gigapixel whole slide images (WSIs) with many patches in pathology and thousands of pathways in genomic data, leading to an ``intra-modal redundancy" issue.

ECL: Class-Enhancement Contrastive Learning for Long-tailed Skin Lesion Classification

1 code implementation9 Jul 2023 Yilan Zhang, Jianqi Chen, Ke Wang, Fengying Xie

In this paper, we propose class-Enhancement Contrastive Learning (ECL), which enriches the information of minority classes and treats different classes equally.

TFormer: A throughout fusion transformer for multi-modal skin lesion diagnosis

1 code implementation21 Nov 2022 Yilan Zhang, Fengying Xie, Jianqi Chen

Multi-modal skin lesion diagnosis (MSLD) has achieved remarkable success by modern computer-aided diagnosis (CAD) technology based on deep convolutions.

Geometrical Characterization of Sensor Placement for Cone-Invariant and Multi-Agent Systems against Undetectable Zero-Dynamics Attacks

no code implementations10 May 2021 Jianqi Chen, Jieqiang Wei, Wei Chen, Henrik Sandberg, Karl H. Johansson, Jie Chen

Undetectable attacks are an important class of malicious attacks threatening the security of cyber-physical systems, which can modify a system's state but leave the system output measurements unaffected, and hence cannot be detected from the output.

Mean-Square Stability and Stabilizability Analyses of LTI Systems Under Spatially Correlated Multiplicative Perturbations

no code implementations10 Dec 2021 Jianqi Chen, Tian Qi, Jie Chen

In this paper, we investigate the mean-square stability and stabilizability problems for linear time-invariant systems under stochastic spatially correlated multiplicative uncertainties.

Errors Dynamics in Affine Group Systems

no code implementations31 Jul 2023 Xinghan Li, Jianqi Chen, Han Zhang, Jieqiang Wei, Junfeng Wu

In this paper, we focus on the error dynamics analysis for an affine group system under external disturbances or random noises.

Phase Preservation of N-Port Networks under General Connections

no code implementations28 Nov 2023 Jianqi Chen, Wei Chen, Chao Chen, Li Qiu

In addition, the inverse operations of the considered connections, that is, network subtractions with correspondences are examined.

A Cyclic Small Phase Theorem

no code implementations1 Dec 2023 Chao Chen, Wei Chen, Di Zhao, Jianqi Chen, Li Qiu

This paper introduces a brand-new phase definition called the segmental phase for multi-input multi-output linear time-invariant systems.
