Data Entry, Management, and Curation

Use AI software to ensure your data are free of errors and other issues (outliers, near duplicates, low-quality examples). Cleanlab can automatically detect which values are incorrect in data entries and associated metadata (e.g. annotations or tags for images/documents).

Quote from Seah Bei Ying, Data Analyst at The Stakeholder Company:
We used Cleanlab to quickly validate one of our classifier models’ predictions for a dataset. This is typically a very time-consuming task since we would have to check thousands of examples by hand. However, since Cleanlab helped us identify the data points that were most likely to have label errors, we only had to inspect an eighth of our dataset to see that our model was problematic. We later realized that this was due to a post-processing error in the dataset — something that would otherwise have taken a much longer time to notice.
The Stakeholder Company's mission is to build tech to connect our divided world by connecting the dots between what's happening and who's making it happen across the world's most important issues.

Case StudyCleanlab Finds Thousands of Errors in ImageNet

ImageNet is the most famous computer vision (image recognition) dataset with millions of images. Cleanlab Studio automatically found tens of thousands of data errors like label issues, outliers, ambiguous examples, and (near) duplicates. The graphic below shows a few of them. Read more.
