我试图运行import { Component } from '@angular/core';

this.data = this.data.replace(/\n/g, "");

let alert = this.alertCtrl.create({

(cforest
包),其数据集为~70k观测值和~105个变量,其中一个是响应变量(二进制)。
cforest的具体信息是party
。
问题在于构建mtry = 10, ntree = 50, maxsurrogate = 3
(2小时50分钟)需要很长时间,而cforest
例如500棵树和ranger
只需要6分钟。我知道每个过程背后的方法是完全不同的,但这个计算成本是否正常?我对调整参数做错了吗?
在构建了cforest之后,我尝试使用函数mtry=10
在一个观察量为~30k的数据集中对其进行评估,并收到以下错误消息:
predict()
我在使用Windows 7的台式计算机上工作,其技术特征是:
非常感谢你的时间。
答案 0 :(得分:1)
使用派对你可以单独构建树,然后将它们组合起来,但这很乏味。来自R-forge的partykit devel版本提供了ctree / cforest的重新实现,旨在提高内存效率。
