X-ScanRefer

ScanReferr facilitates a clear correspondence between expressions and instances in 3D point cloud scenes, enabling effective identification of target objects. However, the explicit mention of the target object in the expression creates a shortcut that filters out negative samples, aiding model learning. In order to mitigate overreliance on this shortcut, we conducted manual processing of the ScanReferr dataset. Specifically,  we replaced the name of the referring object with the term ``object'' while preserving the names of other objects.
