Researchers have identified that the modality gap in shared representation spaces of multimodal models is not a global shift but an anisotropic residual structure. They propose a new principle for modality alignment that preserves the semantic structure of the source modality while adapting to the target modality's distribution. This leads to a framework called AnisoAlign, which uses geometric correction to create substitute representations for training multimodal models with unimodal data. AI
