Sorry if it wasn't clear, I do mention the linear classification protocol several times in the post. If you want to evaluate performance on a classification task, you have to show it labels during evaluation, otherwise it's an impossible task. Note that the encoder is freezed during evaluation, and only a linear classifier is trained on top. Now, even when evaluated on a limited set of labels (as low as 1%), contrastive pretraining outperforms purely supervised training by a large margin (check out Figure 1 in the Data-Efficient CPC paper: https://arxiv.org/abs/1905.09272. I did not get the…
