Bi3D++: Hybrid Bi-Domain Active Learning for Cross-Domain 3D Object Detection

Bi3D++ is a machine learning method that helps 3D object detection systems (used in autonomous vehicles to identify objects like cars and pedestrians) work better when switching between different environments or sensors. Instead of requiring all new data to be labeled (annotated), it intelligently selects only the most important 1% of new data to label, then uses smart strategies to transfer knowledge from old labeled data to improve detection in the new environment.
