3LC works across CV tasks
Classification
- Find samples which are misclassified by your model
- See per-sample metrics evolve throughout training
- Edit your labels and instantly re-train
Object Detection
- Add, remove, resize or relabel any bounding box
- Filter on per bounding box properties like confidence or IoU
- Apply thousands of edits with a single click based on model
predictions
Segmentation
- View and edit segmentation masks on the per pixel level
- Identify and alleviate class and object size imbalances
- Use custom metrics like per- class IoU to identify why your model struggling
3LC integrates easily into your code

Human in the Loop
Improve your data + model
Data
Debugger
- Find important or inefficient samples
- Understand what samples work and where your model struggles
- Improve your model by changing your data
Dataset
Versioning
- Make sparse, non-destructive edits to individual samples or in a batch
- Maintain a lineage of all changes and restore any previous revisions
- Avoid duplicating data
Experiment
Tracking
- Aggregate metrics by sample features, rather than just epoch, to spot hidden trends
- Tie each training run to a specific dataset revision for full reproducibility
- Find the best combination of model hyperparameters and dataset modifications
