# 12-16 meeting
## Problem Setting
* 根據作者過去寫過的paper，每篇paper視為一個session(basket)
，session(basket)中包含citation，推薦作者下一篇paper(session,basket)的citation。
* train & test：假設要推薦給某作者2019年出投某conference的paper的citation，那麼就將2018以前的所有paper當作train，並將該作者2018以前寫過的paper當作session data去predict。


## Next-Basket Methods
X    basket_T=0~t 預測basket_t 接下來的item
O    basket_T=0~t 預測basket_t+1 會出現的items

## session 前處理
- [x] 照作者切session
- [x] 照每年conference做rolling
- [ ] reference的paper照原始順序/ 年分+月份排序
