Data complexity

Definition

Data complexity refers to the intricacy and multifaceted nature of biological data, often involving high-dimensional datasets that capture various biological processes and interactions. This complexity arises from the multitude of variables and interdependencies among biological systems, making it challenging to analyze and interpret the data effectively. Understanding data complexity is crucial in systems biology as it influences the modeling, analysis, and interpretation of biological phenomena.
