Consistency and complementary information in multiview or multimodal #29
Description
Hi everyone, I open this issue for the discussion of consistency and complementary information in multiview or multimodal. After reading some papers, I find that many authors would like to talk about consistency between modalities (e.g., the similarity between modalities) or the complementary information across the modalities. Yes, the consistency can enhance some signals that are not so remarkable in one modality and the complementary information can supplement the information that one view or modal does not exist. But I do not clearly understand why we need them? What's more, I do not find any mathematical explanation about it. Can anybody provide some comprehensive understanding about them?
