A dual-branch model with inter- and intra-branch contrastive loss for long-tailed recognition

no code implementations28 Sep 2023 Qiong Chen, Tianlin Huang, Geren Zhu, Enlu Lin

Therefore, in this paper, we propose a simple yet effective model, named Dual-Branch Long-Tailed Recognition (DB-LTR), which includes an imbalanced learning branch and a Contrastive Learning Branch (CoLB).

MIANet: Aggregating Unbiased Instance and General Information for Few-Shot Semantic Segmentation

1 code implementation CVPR 2023 Yong Yang, Qiong Chen, Yuan Feng, Tianlin Huang

Existing few-shot segmentation methods are based on the meta-learning strategy and extract instance knowledge from a support set and then apply the knowledge to segment target objects in a query set.

On-edge Multi-task Transfer Learning: Model and Practice with Data-driven Task Allocation

no code implementations6 Jul 2021 Zimu Zheng, Qiong Chen, Chuang Hu, Dan Wang, Fangming Liu

We then show that task allocation with task importance for MTL (TATIM) is a variant of the NP-complete Knapsack problem, where the complicated computation to solve this problem needs to be conducted repeatedly under varying contexts.

Pulsed polarisation for robust DNP

1 code implementation4 Oct 2017 Ilai Schwartz, Jochen Scheuer, Benedikt Tratzmiller, Samuel Mueller, Qiong Chen, Ish Dhand, Zhenyu Wang, Christoph Mueller, Boris Naydenov, Fedor Jelezko, Martin B. Plenio

We derive sequences theoretically and demonstrate experimentally that they are capable of efficient polarisation transfer from an optically polarised nitrogen-vacancy centre in diamond to the surrounding $^{13}$C nuclear spin bath even in the presence of control errors, making it an ideal tool for the realisation of the above NV centre based applications.

Robust techniques for polarization and detection of nuclear spin ensembles

1 code implementation5 Jun 2017 Jochen Scheuer, Ilai Schwartz, Samuel Müller, Qiong Chen, Ish Dhand, Martin B. Plenio, Boris Naydenov, Fedor Jelezko

Here we demonstrate the polarization and read out of a nuclear spin bath consisting of $^{13}$C nuclear spins in diamond by using a single nitrogen-vacancy (NV) center.
