Datasets

MS-COCO and Flickr30K

We follow SCAN to obtain image features and vocabularies.

CC152K

We use a subset of Conceptual Captions (CC), named CC152K. CC152K contains training 150,000 samples from the CC training split, 1,000 validation samples and 1,000 testing samples from the CC validation split. We follow the pre-processing step in SCAN to obtain the image features and vocabularies.
