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...

2023/11/29
Dirac方程最初是Dirac为解决Minkowski时空中Klein—Gordon方程的粒子的负几率与负能问题建立的。1980年，Weinberg和Witten证明了引力无法量子化，所以为了将引力引入量子场论中，数学和物理学家将平直时空的Dirac方程推广到弯曲时空的Dirac方程，弯曲时空Dirac方程表示了任一自由费米子物质场在时空背景所应满足的场方程，是宇宙学研究的核心问题。2000年Fi...
