作者您好，可以麻烦提供一份论文呢的pdf吗？
This repo is an incredibly intriguing work and I am eager to replicate your experimental results starting from the raw check-in data. I would appreciate more details on how you preprocess those raw check-in data. If you can share the data preprocessing code, that would be immensely helpful.
求一份大佬的数据预处理代码
按照文章中陈述的预处理步骤：
1.数据清洗
2.通过用户、时间划分轨迹
3.通过时间划分训练集、验证集、测试集
处理后的数据会导致训练集中POI并没有包含所有的POI，即测试集中会出现新POI，而代码中似乎没有对此做一些特殊处理。
我尝试用自己的数据集处理后运行代码，但是因为这个问题，训练过程没有问题，但测试中报了KeyError
