Learning Generalizable Models via Disentangling Spurious and Enhancing Potential Correlations

1 code implementation11 Jan 2024 Na Wang, Lei Qi, Jintao Guo, Yinghuan Shi, Yang Gao

2) From the feature perspective, the simple Tail Interaction module implicitly enhances potential correlations among all samples from all source domains, facilitating the acquisition of domain-invariant representations across multiple domains for the model.

Automatic lobe segmentation using attentive cross entropy and end-to-end fissure generation

no code implementations24 Jul 2023 Qi Su, Na Wang, Jiawen Xie, Yinan Chen, Xiaofan Zhang

Therefore, we propose a new automatic lung lobe segmentation framework, in which we urge the model to pay attention to the area around the pulmonary fissure during the training process, which is realized by a task-specific loss function.

ALOFT: A Lightweight MLP-like Architecture with Dynamic Low-frequency Transform for Domain Generalization

1 code implementation CVPR 2023 Jintao Guo, Na Wang, Lei Qi, Yinghuan Shi

However, the local operation of the convolution kernel makes the model focus too much on local representations (e. g., texture), which inherently causes the model more prone to overfit to the source domains and hampers its generalization ability.

Compressed Sensing Based RFI Mitigation and Restoration for Pulsar Signals

no code implementations The Astrophysical Journal 2022 Hao Shan, Jianping Yuan, Na Wang, Zhen Wang

In pulsar signal processing, two primary difficulties are (1) radio-frequency interference (RFI) mitigation and (2) information loss due to preprocessing and mitigation itself.

PP-MSVSR: Multi-Stage Video Super-Resolution

1 code implementation6 Dec 2021 Lielin Jiang, Na Wang, Qingqing Dang, Rui Liu, Baohua Lai

Different from the Single Image Super-Resolution(SISR) task, the key for Video Super-Resolution(VSR) task is to make full use of complementary information across frames to reconstruct the high-resolution sequence.

The first evidence for three-dimensional spin-velocity alignment in pulsars

no code implementations2 Mar 2021 Jumei Yao, Weiwei Zhu, Richard N. Manchester, William A. Coles, Di Li, Na Wang, Michael Kramer, Daniel R. Stinebring, Yi Feng, Wenming Yan, Chenchen Miao, Mao Yuan, Pei Wang, Jiguang Lu

Observations have shown a strong tendency for alignment of the pulsar space velocity and spin axis in young pulsars but, up to now, these comparisons have been restricted to two dimensions.
