DocStormer: Revitalizing Multi-Degraded Colored Document Images to Pristine PDF

no code implementations27 Oct 2023 Chaowei Liu, Jichun Li, Yihua Teng, Chaoqun Wang, Nuo Xu, Jihao Wu, Dandan Tu

Thus, we propose DocStormer, a novel algorithm designed to restore multi-degraded colored documents to their potential pristine PDF.


Generating Synergistic Formulaic Alpha Collections via Reinforcement Learning

1 code implementation25 May 2023 Shuo Yu, Hongyan Xue, Xiang Ao, Feiyang Pan, Jia He, Dandan Tu, Qing He

In practice, a set of formulaic alphas is often used together for better modeling precision, so we need to find synergistic formulaic alpha sets that work well together.

Intrinsic Bias Identification on Medical Image Datasets

no code implementations24 Mar 2022 Shijie Zhang, Lanjun Wang, Lian Ding, An-An Liu, Senhua Zhu, Dandan Tu

However, scientists and practitioners are difficult to identify implicit biases in the datasets, which causes lack of reliable unbias test datasets to valid models.

DuCN: Dual-children Network for Medical Diagnosis and Similar Case Recommendation towards COVID-19

no code implementations3 Aug 2021 Chengtao Peng, Yunfei Long, Senhua Zhu, Dandan Tu, Bin Li

Our proposed network contains two stages: the first one is a lung region segmentation step and is used to exclude irrelevant factors, and the second is a detection and recommendation stage.
