## Dataset
- ccs_ebdataset: CC3M-CC12M-SBU filtered by CLIP, we directly download the webdataset based on the [released of curated subset of BLIP-1](https://github.com/salesforce/BLIP)
- datacomp_medium_dfn_webdataset: DataComp-Medium-128M filtered by DFN, we just select this subset based the uids released by DFN
- datacomp_medium_mlm_filter_su_85_union_dfn_webdataset: DataComp-Medium-128M filtered by DFN union DataComp-Medium-128M filtered by MLM-Filter based on the semantic understanding metric with threshold 85
