Mind the Gap: Understanding the Modality Gap in Multi-modal Contrastive Representation Learning

Neural Information Processing Systems

During optimization, contrastive learning keeps the different modalities separated by a certain distance, which is influenced by the temperature parameter in the loss function. Our experiments further demonstrate that varying the modality gap distance has a significant impact in improving the model's downstream zero-shot classification performance and fairness.


FedL2P: Federated Learning to Personalize

Neural Information Processing Systems

In this paper, we consider the federated meta-learning problem of learning personalization strategies. Specifically, we consider meta-nets that induce the batch-norm and learning rate parameters for each client given local data statistics.
