What each one is
LightGBM
LightGBM trains faster and uses less memory than XGBoost on large datasets, with comparable accuracy.
- Very fast on large data
- Low memory footprint
- Handles categorical features natively
CVAT
CVAT is the professional annotation tool for video and images — bounding boxes, polygons, skeletons, with interpolation across frames.
- Interpolation makes video annotation bearable
- Automatic annotation with your own models
- Used by large annotation teams
Key differences
LightGBM is gradient boosting, while CVAT is video & image annotation. LightGBM leans more beginner-friendly, whereas CVAT is more suited to intermediate users. In short, LightGBM fits large tabular datasets where training time is the bottleneck, and CVAT fits computer vision datasets, especially video.
Which should you choose?
Choose LightGBM for large tabular datasets where training time is the bottleneck. Choose CVAT for computer vision datasets, especially video.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
