Hi everyone. I am working on the keystep recognition benchmark. The Ego-Exo4D paper says: “The keysteps in our dataset exhibit a very longtailed distribution. To address this challenge, we set a cutoff threshold at 20 samples per key step, limiting our analysis to 278 unique key steps”. It raises a couple of questions:
- The limit cutoff of 20 is from the training set or considering train+val+test?
- Will the testing set of the challenge contain only the 278 key steps or all of them?
