Multimodal Learning Recently, various vision-language models (VLMs) have been proposed to enhance the fusion of text and images. For example, TCL [42] employed triplet contrastive learning to simultaneously learn from text and images. Many state-ofthe-art MLLMs have also emerged, with one major distinction lying in the design of VPGs. For instance, FROMAGe [18] and LLaVA [24] employ a straightforward linear projection as their VPGs. On the other hand, Flamingo [2] introduces the novel use of the Perceiver Resampler, incorporating cross attention and learnable query embeddings. BLIP2 [22] innovatively employs the QFormer to improve image-text alignment. Meanwhile, MiniGPT-4 [48] integrates a frozen QFormer with additional learnable layers for enhanced performance. While successful in diverse tasks, current multimodal models are primarily designed under the assumption of a one-to-one relationship between texts and image inputs. In reality, the relationship between text and images can be one-to-many or many-to-many. Effectively applying multimodal models in such scenarios poses an open challenge. Authors:
