The heatmap titled co occurrence matrix plots detector objects on the horizontal axis from 0 to about 80 and P O S concepts on the vertical axis from 0 to about 90. Most cells show very low co occurrence values, forming a dark background. Scattered brighter cells appear at specific intersections, indicating higher co occurrence between certain detector objects and P O S concepts. Vertical streaks at some detector indices suggest repeated associations across multiple P O S concepts. The overall pattern shows sparse but structured co occurrence rather than uniform distribution.
The occurrence matrix of POS tagging concepts and the detection results. The x-axis is the 80 object classes from the pretrained detector from the MS-COCO (Lin et al., 2014) dataset. The y-axis is the top 100 concepts from the POS tagger
