Adaptive Early-Learning Correction for Segmentation from Noisy Annotations

2 code implementations CVPR 2022 Sheng Liu, Kangning Liu, Weicheng Zhu, Yiqiu Shen, Carlos Fernandez-Granda

We discover a phenomenon that has been previously reported in the context of classification: the networks tend to first fit the clean pixel-level labels during an "early-learning" phase, before eventually memorizing the false annotations.

Variationally Regularized Graph-based Representation Learning for Electronic Health Records

1 code implementation8 Dec 2019 Weicheng Zhu, Narges Razavian

A feasible approach to improving the representation learning of EHR data is to associate relevant medical concepts and utilize these connections.

Interpretable Prediction of Lung Squamous Cell Carcinoma Recurrence With Self-supervised Learning

1 code implementation23 Mar 2022 Weicheng Zhu, Carlos Fernandez-Granda, Narges Razavian

The resulting representations and clusters from self-supervision are used as features of a survival model for recurrence prediction at the patient level.

Variational hybridization and transformation for large inaccurate noisy-or networks

no code implementations20 May 2016 Yusheng Xie, Nan Du, Wei Fan, Jing Zhai, Weicheng Zhu

In addition, we propose a transformation ranking algorithm that is very stable to large variances in network prior probabilities, a common issue that arises in medical applications of Bayesian networks.
