Thanks for your interesting work!

I would like to know some details of how you perform kNN classifier on the ImageNet-LT dataset, including the number of K and the temperature used in exp(cos_sim / t). Besides, which set of the dataset (train, validation or both) is used to be the support set to search for kNN? Thanks!

Hi, for KNN classifier on ImageNet-LT, we used the support set from training set and use the same number of K and temperature as in the experiment on ImageNet. Sorry for the late reply
