A Survey of Heterogeneous Transfer Learning

1 code implementation12 Oct 2023 Runxue Bao, Yiming Sun, Yuhe Gao, Jindong Wang, Qiang Yang, Haifeng Chen, Zhi-Hong Mao, Ye Ye

These methods typically presuppose identical feature spaces and label spaces in both domains, known as homogeneous transfer learning, which, however, is not always a practical assumption.

Prediction of COVID-19 Patients' Emergency Room Revisit using Multi-Source Transfer Learning

no code implementations29 Jun 2023 Yuelyu Ji, Yuhe Gao, Runxue Bao, Qi Li, Disheng Liu, Yiming Sun, Ye Ye

Results showed that the Multi-DANN models outperformed the Single-DANN models and baseline models in predicting revisits of COVID-19 patients to the ER within 7 days after discharge.

Multi-modal Gated Mixture of Local-to-Global Experts for Dynamic Image Fusion

1 code implementation ICCV 2023 Yiming Sun, Bing Cao, Pengfei Zhu, QinGhua Hu

The MoLE performs specialized learning of multi-modal local features, prompting the fused images to retain the local information in a sample-adaptive manner, while the MoGE focuses on the global information that complements the fused image with overall texture detail and contrast.

Infrared And Visible Image Fusion

DetFusion: A Detection-driven Infrared and Visible Image Fusion Network

1 code implementation ACMMM 2022 Yiming Sun, Bing Cao, Pengfei Zhu, QinGhua Hu

We cascade the image fusion network with the detection networks of both modalities and use the detection loss of the fused images to provide guidance on task-related information for the optimization of the image fusion network.

Single Pass Entrywise-Transformed Low Rank Approximation

no code implementations16 Jul 2021 Yifei Jiang, Yi Li, Yiming Sun, Jiaxin Wang, David P. Woodruff

A natural way to do this would be to simply apply $f$ to each entry of $A$, and then compute the matrix decomposition, but this requires storing all of $A$ as well as multiple passes over its entries.

Local Aggressive Adversarial Attacks on 3D Point Cloud

1 code implementation19 May 2021 Yiming Sun, Feng Chen, Zhiyu Chen, Mingjie Wang

However, the perturbations of global point are not effective for misleading the victim model.

Tensor Random Projection for Low Memory Dimension Reduction

no code implementations30 Apr 2021 Yiming Sun, Yang Guo, Joel A. Tropp, Madeleine Udell

The TRP map is formed as the Khatri-Rao product of several smaller random projections, and is compatible with any base random projection including sparse maps, which enable dimension reduction with very low query cost and no floating point operations.

Multi-Drone based Single Object Tracking with Agent Sharing Network

1 code implementation16 Mar 2020 Pengfei Zhu, Jiayu Zheng, Dawei Du, Longyin Wen, Yiming Sun, QinGhua Hu

Moreover, an agent sharing network (ASNet) is proposed by self-supervised template sharing and view-aware fusion of the target from multiple drones, which can improve the tracking accuracy significantly compared with single drone tracking.

Drone-based RGB-Infrared Cross-Modality Vehicle Detection via Uncertainty-Aware Learning

2 code implementations5 Mar 2020 Yiming Sun, Bing Cao, Pengfei Zhu, QinGhua Hu

To address this dilemma, we further propose an uncertainty-aware cross-modality vehicle detection (UA-CMDet) framework to extract complementary information from cross-modal images, which can significantly improve the detection performance in low light conditions.
