Data Association
Data Association refers to the problem to matching data points across different sets of data (ex: associating a 2D bounding box with a 3D bounding box).
Feature Matching is data association for the same kind of data.
First heard about when Alvin told me that we needed to do Data Association from 2D to 3D.
Then, in the context of F1TENTH, learning about data association.
If you have two same ROS nodes making predictions. You need a simple algorithm to associate the ones that are the same predictions. You don’t want to predict twice.
