New 'information density' metric tackles bias in visual object detection

Researchers have introduced a new concept called "information density" to explain category bias in visual object detection models, moving beyond the traditional focus on instance counts. They observed a negative correlation between a category's information density and its accuracy, suggesting that imbalances in information density, not just instance numbers, contribute to model bias. By incorporating information density into object detection loss functions, experiments on PASCAL VOC, COCO-LT, and LVIS datasets showed a reduction in model bias and an improvement in overall performance.
