 **\*\*\*\*\* New March 12th, 2021: New cnn/rcnn feature on test/valid dataset \*\*\*\*\***
 
 We fixed the bug of cnn/rcnn features on valid/test dataset and re-run the experiments on the new data.

-We upload a new version(1.1) of our dataset, which adopt the train/valid/test split of dataset consistent with 
-our paper(1M, 50k, 50K), while the older split is (900K, 100k, 100k). The download urls are updated too. 
-**Note: cnn/rcnn features of valid/test dataset are incorrect now, and we will update it soon.**
