We developed a framework to reconstruct complex networks with many-body interactions from time-series data. This method accurately identifies network connections and topology, even with noisy data.
Area of Science:
- Network Science
- Complex Systems
- Statistical Inference
Background:
- Prior research focused on reconstructing networks with pairwise interactions.
- Growing interest in higher-order (many-body) interactions necessitates new reconstruction methods.
- Observational data requires robust techniques for inferring complex network structures.
Purpose of the Study:
- To develop a general framework for reconstructing 2-simplicial complexes with two- and three-body interactions.
- To utilize binary time-series data from discrete-state dynamics for network reconstruction.
- To improve reconstruction accuracy and computational efficiency.
Main Methods:
- Combined statistical inference and expectation maximization.
- Developed a two-step scheme for enhanced accuracy and reduced computational load.
- Validated using synthetic and real-world 2-simplicial complex data.
Main Results:
- Successfully reconstructed 2-simplicial complexes with two- and three-body interactions.
- All network connections were faithfully identified.
- The full topology of the complexes was accurately inferred.
Conclusions:
- The proposed framework effectively reconstructs complex networks with higher-order interactions.
- The method demonstrates robustness against noisy data and stochastic disturbances.
- Enables detailed topological inference from observational time-series data.

Cyclic Processes And Isolated Systems
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state.
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...
