## 論文部分
### ResNets變體 -- ResNeSt: Split-Attention Networks
發表團隊:Amazon,University of California, Davis
日期:2020/04/19
結合了SENet，SKNet 和 ResNeXt

Split-Attention:

r個張量先sum，然後global average pooling，先經過一層fc，bn，relu，得到中間向量特徵，再分別經過r個fc，每個fc的輸出都是c維，得到r個c維向量

## 下周預計:
目前看了部分發現對於attention機制、ResNext理解不足，下周會先從attention開始理解
## 其他 cross entropy理解
