Extended Data Fig. 9. Parameter sensitivity: Evaluation of number of body parts, frames, and PAF sizes.
(a) The number of keypoints affects mAP; evaluated with ResNet50 stride8 on the two datasets with the most keypoints originally labeled by subsampling the keypoints. [Mouse: snout/tailbase (2) + leftear/rightear (4) + shoulder/spine1/spine2/spine3 (8) vs. full (12); Marmoset: Middle/Body2 (2) + FL1/BL1 /FR1/BR1/Left/Right (8) + front/body1/body3 (11) vs. full (15)] (b) Identity prediction is not strongly affected by the number of keypoints used (same experiments as in a, but for identity). (c) Impact of graph size, and randomly dropping edges on performance. (d) Test performance on 30% of the data vs. training set size (as fraction of 70%) for all four datasets.
