logistic回归模型OR通俗解释 logistic回归模型结果 逻辑回归的基本过程:a建立回归或者分类模型--->b 建立代价函数 ---> c 优化方法迭代求出最优的模型参数 --->d 验证求解模型的好坏。 1.逻辑回归模型: 逻辑回归(Logistic Regression):基于线性回归的分类算法。一般用于解决二分类问题。
R软件中的elrm(exact-like inference in logistic regression models)包可以实现这一过程。 library(elrm) data(drugDat);包中自带的数据“drugDat” drug.elrm = elrm(formula=recovered/n~sex+treatment, interest=~sex+treatment, r=4,iter=40000, burnIn=1000, dataset=drugDat); ...

作者在 FTL 中使用了两种常见的 logistic 回归(Logistic Regression,LR)模型,即同质 LR 和异质 LR。根据同质模型和异构模型目标的不同,将数据库分为纵向和横向两部分。横向划分处理后生成同质模型所需的不同数据样本,而纵向划分处理后的数据库则具有不同的特征空间,用于构建异构模型。作为比较,作者使用 Tensorflowv...
