Tensor decomposition (TD) is a powerful mathematical framework for analyzing high-dimensional and multi-way data, such as medical images, biomedical signals, and clinical measurements. Unlike conventional matrix-based methods, TD represents a tensor as a combination of lower-dimensional factor matrices or core tensors, enabling the extraction of latent structures while preserving the intrinsic multi-dimensional relationships within the data.
In medicine, many datasets (e.g., MRI, PET, CT, EGG, EMG ) can be naturally exhibited as a tensor structure. For example, medical imaging data can be organized according to spatial dimensions, time, imaging modality, or patients, while physiological signals may involve multiple subjects, channels, and temporal measurements. Tensor decomposition can therefore provide compact representations, reduce computational and storage costs, and facilitate the discovery of meaningful patterns and biomarkers.
