Temporal network analysis

Definition

Temporal network analysis is the study of dynamic networks that change over time, focusing on how interactions, relationships, and structures evolve. This type of analysis is crucial in understanding biological systems, where relationships between entities, such as genes or proteins, can be influenced by temporal factors, revealing insights into their functional dynamics.
