Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：基于stPCA降维算法的ICU病人出院策略法
stPCA降维算法 ICU病人 出院策略法
2023/12/11
许多复杂生物系统可以由高维非线性动力系统描述，对原始数据进行降维有助于对这些系统进行有效分析。然而以一种可解释的方式进行极致低尺度的降维仍然是一个具有挑战性的问题。基于Takens延迟嵌入理论，将高维空间信息转换为低维时间信息，我们开发了极致低降维算法stPCA，并将其应用于重症监护医疗信息管理系统MIMIC-III和MIMIC-IV数据集，提出了ICU病人的出院决策。stPCA基于ICU患者的高...
