Supplementary Information: Tracking Without Re-recognition in Humans and Machines

In this work we tested a relatively small number of PathTracker versions. One potential issue is determining when a visual system should rely on appearance-based vs. appearance-free features for tracking. Our solution is two-pronged and potentially insufficient. The first strategy is for top-down feedback from the TransT into the InT, which we aligns tracks between the two models. Additional work is needed to identify better approaches.
