Does anybody know community-driven open data platforms?
For example, consider object detection task. Then, next platforms come to my mind: Kaggle and Roboflow. However, in my opinion, both has a significant issue that makes it difficult to use these platforms as ready-to-go data sources. The issue is the community members inability to make pull requests to existing datasets, which could fix their issues (train-test contamination, inaccurate labeling and so on).
TLDR: Is there any GitHub-like open data platform? Was it there, but commercial failure happened?
