Tucker Decomposition

from class:

Metabolomics and Systems Biology

Definition

Tucker decomposition is a mathematical technique used to analyze multi-dimensional data by breaking it down into a core tensor and a set of factor matrices. This method helps in reducing the complexity of high-dimensional datasets while preserving the essential information, making it particularly valuable for multi-omics data integration and systems biology approaches.
