Improving Deep Embedded Clustering via Learning Cluster-level Representations

no code implementations COLING 2022 Qing Yin, Zhihua Wang, Yunya Song, Yida Xu, Shuai Niu, Liang Bai, Yike Guo, Xian Yang

In this paper, we propose a novel DEC model, which we named the deep embedded clustering model with cluster-level representation learning (DECCRL) to jointly learn cluster and instance level representations.

Label-dependent and event-guided interpretable disease risk prediction using EHRs

1 code implementation18 Jan 2022 Shuai Niu, Yunya Song, Qing Yin, Yike Guo, Xian Yang

Thirdly, both label-dependent and event-guided representations are integrated to make a robust prediction, in which the interpretability is enabled by the attention weights over words from medical notes.

Label Dependent Attention Model for Disease Risk Prediction Using Multimodal Electronic Health Records

1 code implementation18 Jan 2022 Shuai Niu, Qing Yin, Yunya Song, Yike Guo, Xian Yang

In this paper, we propose a label dependent attention model LDAM to 1) improve the interpretability by exploiting Clinical-BERT (a biomedical language model pre-trained on a large clinical corpus) to encode biomedically meaningful features and labels jointly; 2) extend the idea of joint embedding to the processing of time-series data, and develop a multi-modal learning framework for integrating heterogeneous information from medical notes and time-series health status indicators.
