Manifold alignment refers to a process of matching multiple datasets that are represented in high-dimensional space, such as images or DNA sequences. It is a crucial technique in many fields, including computer vision, bioinformatics, and machine learning. As with any other technical term, manifold alignment has various synonyms that describe the same concept. Some of the synonyms for manifold alignment include multi-view alignment, multi-modal alignment, cross-modal alignment, cross-domain alignment, and joint alignment. Although these terms may differ in their semantics, they all share the same goal of aligning multiple datasets to facilitate their analysis and comparison. The use of manifold alignment synonyms helps researchers to identify and communicate complex ideas in their field.
