AI总结:

BoXHED2.0是一种高效的非参数化树提升方法,用于处理动态生存分析中的时间依赖性协变量和复杂生存设置。

摘要:

现代生存分析的应用越来越多地涉及时间依赖性协变量。Python包BoXHED2.0是一种基于树的危险估计器,完全非参数化,适用于比右删失更广泛的生存设置,包括复发事件和竞争风险。BoXHED2.0可扩展到与参数提升生存模型相同数量级的速度,部分原因是其核心用C++编写,并且也支持GPU和多核CPU的使用。BoXHED2.0可通过PyPI和www.github.com/BoXHED获取。

英文摘要:

Modern applications of survival analysis increasingly involve time-dependent covariates. The Python package BoXHED2.0 is a tree-boosted hazard estimator that is fully nonparametric, and is applicable to survival settings far more general than right-censoring, including recurring events and competing risks. BoXHED2.0 is also scalable to the point of being on the same order of speed as parametric boosted survival models, in part because its core is written in C++ and it also supports the use of GPUs and multicore CPUs. BoXHED2.0 is available from PyPI and also from www.github.com/BoXHED.
