CLOOB: Modern Hopfield Networks with InfoLOOB Outperform CLIP

Fürst, Andreas, Rumetshofer, Elisabeth, Lehner, Johannes et al.

Understand

CLIP yielded impressive results on zero-shot transfer learning tasks and is considered as a foundation model like BERT or GPT3.

  • CLIP vision models that have a rich representation are pre-trained using the InfoNCE objective and natural language supervision before they are fine-tuned on particular tasks.
  • Though CLIP excels at zero-shot transfer learning, it suffers from an explaining away problem, that is, it focuses on one or few features, while neglecting other relevant features.
  • This problem is caused by insufficiently extracting the covariance structure in the original multi-modal data.
