Table 4.
AMI score comparison in K-Means (k = 2) clusterings of models trained with two SSRL losses versus an ImageNet pre-trained encoder on Nocodazole, Cytochalasin B, and Taxol treated cell subsets. One SSRL loss uses color jitter, flips, rotation, affine transformation, and random cropping; the other, rotations, center cropping, color jitter, and flips. Careful selection of transformation sets, tailored to desired features, enhances clustering performance in self-supervised training over supervised pre-trained models, even in small datasets.
