慢加急性肝衰竭预后评分系统的建立与评估

open access: yes, 2011
【目的】 建立一个简单实用的慢加急性肝衰竭预后评分系统65377;【方法】 558例慢加急性乙型肝炎肝衰竭,按临床结局分为存活组和死亡组,按9 ∶ 1分成训练样本(499例)和测试样本(59例)65377;首先进行单变量分析,选择对预后最有影响且临床易于评估的一些因素并按其程度分别赋予一定的分值,计算患者综合评分65377;利用这些指标,采用Fisher判别分析法建立预后评分系统,求得判别方程和判别界值65377;运用判别方程在训练样本中做回代判别和交互验证,在测试样本中进行组外考核 ...

BP神经网络和SVM在矿山环境评价中的应用分析/Application of BP neural network and SVM in mine environmental assessment[J]

open access: yes, 2015
矿山环境的影响因素多样,定量评价过程易受人为因素干预.BP神经网络与SVM算法能够自动模拟各因子间的非线性关系.首次将其引入到矿山环境评价中,选取160个单元作为训练样本,以自然地理、基础地质、开发占地及地质环境等4个大类的14个变量指标为输入向量,以单元评价得分为输出向量,分别建立BP神经网络与SVM矿山环境评价模型.结果表明:两种模型均能满足矿山环境评价的精度要求;SVM模型收敛速度较BP神经网络快,MSE小于BP神经网络,更适合矿山环境评价工作;将定量模型应用于研究区,评价得分划分为4个级别 ...
