发帖数: 715 | 5 流失定义为半年内客户不再来访。已知过去10年所有客户的访问和消费数据，年龄性别
等。想要建一个系统每个月预测一下客户离开的概率。
简单的思路是 做feature engineering,用svm或者logistic regression。主要的问题
是，时间序列数据怎么处理seasonal effect和trend？是否有必要做per customer的
model? 或者用rnn? |

死了都不知道怎么死的。
我最喜欢埋伏或者潜伏，不太喜欢追高。
最近做的最成功的属于RNN和AEZS。
HLCS前半段还可以，后面死的挺挺的。 |

我觉得这个问题很重要, 特别对这里. 因为常常看一些童鞋上来说捂N个月,跌了40~50%. 跌到这个份上的话, 要是仓位重的话谁也帮不了了.
我个人觉得小股, 垃圾股(低于5块)上下幅度比较大, 止损也松一点,15%. 要是跌幅过了15%, 基本说明你选错股了, 至少也是入场点很差. 应该先出场观望一下. 另外,接飞刀和追涨又不一样了. 这两种常常是头脑发热, 入场很冲动, 所以止损要紧一点,10%.
我先抛个砖,也欢迎来拍砖.
