随机生存森林是随机森林处理生存数据的扩展方法。随机生存森林是随机生长的生存树的集合。每棵树都是使用随机采样的样本子集,在每个节点上随机选择特征构造的。随机生存森林中的树深度通常非常大,有许多叶子节点。考虑竞争风险的随机生存森林也以类似的方式构造,并在叶子节点内计算风险估计值。考虑竞争风险的随机生存森林...

Is random survival forest an alternative to Cox proportional model on predicting cardio- vascular disease? In: Lackovic I, Vasic D, editors. 6th European Conference of the International Federation for Medical and Biological Engineering. IFMBE Proceedings: 45; 740-743. Springer, Cham; 2015....
$ pip install random-survival-forest Contribute Source Code:https://github.com/julianspaeth/random-survival-forest Performance This implemention is not optimized for being highly performant. It is programmed in pure python. If you have large datasets (large sample size) or use a very high number...
In this work, we extended the competing-risk random survival forests to handle such endogenous longitudinal predictors when predicting event probabilities. The method, implemented in the R package DynForest, internally transforms the time-dependent predictors at each node of each tree into time-fixed ...
Random survival forest for Competing Risks (CR Rsf) is a tree-based estimation and prediction method. The applications of this recently proposed method have not yet been considered in the extant credit risk literature. The appealing features of CR Rsf compared to the existing competing risks ...
EFS modeling approaches, including a random survival forest wherein variables were eliminated using recursive feature elimination (a commonly utilized feature reduction approach), a multivariable Cox proportional hazards model, and a random survival forest model using current gold-standard prognostic ...

A random survival forest model was derived and compared with a Cox proportional hazards model derived from traditional cardiovascular risk factors (ie, the variables used to estimate the Pooled Cohort Equations for the primary prevention population and the variables used to estimate the Second ...
