ML practitioners struggle with hyperparameter selection for self-supervised learning

By PulseAugur Editorial · [1 sources] ·

Machine learning practitioners face challenges in selecting optimal hyperparameters and architectures for self-supervised representation learning, particularly when the loss function is non-monotonic. Methods like BYOL, JEPA, and data2vec show promise, but understanding what is being learned and evaluating performance is difficult. While tools like RankMe exist to assess learning by analyzing embedding matrices, their effectiveness is questioned when integrated into non-monotonic loss functions, raising the need for alternative evaluation criteria.

    <!-- SC_OFF --><div class="md"><p>Non-contrastive SSL methods like BYOL/JEPA/data2vec seem promising, but I have no idea what is being learned, or how well; it’s models all the way down. Maybe I’ve got supervised tasks for which I’d like to see transfer, and I can evaluate linear…
