The evaluation methods for DINOv2 are k-nn clustering and linear probing. 90% of the data is randomly selected as the training set while the 10% is selected as test set. The k=20 is selected for evaluation with K-NN. The evaluation datasets are including below table. The splited data is stored in linprob_data_lists.
