# UQ-DAAAM

A robot that files a hallway defibrillator under fire extinguisher would carry that wrong description in memory. MIT researchers added uncertainty quantification to the existing DAAAM memory system, so the robot compares descriptions of the same object from different viewpoints, estimates how unsure it is about what it saw, and selects extra views to fuse a more accurate caption. Against baseline methods, the system raised object-description accuracy by 5 percent and resolved ambiguity for about 92 percent of objects using only two additional captions per object.
