Sepsis is one of the main causes of death in ICU patients, and accurate and stable early prediction is essential for clinical intervention. Existing methods mostly rely on traditional time series models (e.g., LSTM, Transformer) or clinical scoring criteria (e.g., SOFA, qSOFA), but face two major challenges: 1) spurious correlations in the data affect the robustness of the model; 2) Lack of modeling the underlying causal relationships in the data space. We propose a Serialized Causal Disentanglement Model (SCDM) that decouples latent variables into sepsis-related factors ($u$), other disease-related factors ($v$), and irrelevant confounders ($s$). Based on the MIMIC-IV v2.2 dataset (3,511 positive samples and 17,538 negative samples), SCDM took patient clinical indicators, personal information, and clinical notes as input, and achieved an AUC of 0.765-0.928in the prediction task 48 to 0 hours before the onset of sepsis. The performance is significantly better than the baseline models (e.g., Transformer's 0.662-0.910, MGP-AttTCN's 0.692-0.913). Experiments show that optimizing the time window (5 hours of continuous observation) and variable selection (45 key indicators) can improve the performance of the model. The effectiveness of causal unwinding is verified by the visualization of Grad CAM and t-SNE, key clinical indicators such as platelet count, lactic acid, and respiratory rate are further identified to provide interpretable decision support for doctors. Our study provides a high-precision and interpretable causal disentanglement framework for early prediction of sepsis, which is expected to promote the development of intelligent diagnosis and treatment in the ICU.

View-based 3D model retrieval has become an important task in both computer vision and machine learning domains. Although deep learning methods have achieved excellent performances on view-based 3D model retrieval, the intrinsic correlation and the degree of view discrimination among multiple views in a 3D model have not been effectively exploited. To obtain a more efficient feature descriptor for 3D model retrieval, in this work, we propose the pairwise view weighted graph network (abbreviated PVWGN) for view-based 3D model retrieval where non-local graph layers are embedded into the network architecture to automatically mine the intrinsic relationship among multiple views of a 3D model. Furthermore, the view weighted layer is employed in the PVWGN to adaptively assign the weight to each view according to its aggregation information. In addition, the pairwise discrimination loss function is designed to improve the feature discrimination of the 3D model. Most importantly, these three issues are integrated into a unified framework. Extensive experimental results on the ModelNet40 and ModelNet10 3D model retrieval datasets show that PVWGN can outperform all state-of-the-art methods on the 3D model retrieval task with mAPs of 93.2% and 96.2%, respectively.
