阿里2015年天池大数据比赛,采用移动窗口采样加随机森林学习
你好!请问一下抽样策略具体是什么样的,还有是不是还有部分代码没有提交啊,希望能得到你的答复,谢谢!
你好,请教个问题:
采用移动窗口target(17、15、13、11、9)+移动窗口样本采样(1、3、7、全部)
如果在某个窗口中,有特殊节假日,比如国庆,而国庆的销量特别高,比如:
移动窗口采样遇到10月1号,而把10月1号的数据直接拿来做特征,会导致这个特征值很高,
请问如何处理这种情况呢,谢谢。
我看你提取特征是不是都用的python啊,总感觉用sql会快一点
你好!
我看了您的代码,但是对于预测的样本数据的产生不是很理解!
您貌似是通过距离预测的日期的前9天的数据为样本进行数据作为样本数据!
请问这么做有什么具体的说明么?
谢谢!
感谢!请问各部分运行顺序是?程序一直报错,少了一些文件
可以联系你吗?我的q 165116190
