Data fusion

Definition

Data fusion is the process of integrating multiple sources of data to create a more comprehensive understanding of a phenomenon. This technique is especially useful in analyzing complex biological systems where different types of omics data, such as genomics, proteomics, and metabolomics, can provide complementary insights. By combining data from various levels, researchers can improve the accuracy and reliability of their findings and facilitate a deeper understanding of disease mechanisms, complex diseases, and the interactions between different biological networks.
