Existing 3D understanding datasets typically provide annotations for a limited number of object classes, with sufficient examples per class. However, real-world object classes are not equally represented in practical settings, leading to poor performance on rarely-occurring categories if the class imbalance is neglected. In this work, we address the challenge of 3D semantic segmentation with a lon...
