Area of Science:

• Neuroscience
• Computational Biology
• Medical Imaging

Background:

• Brain networks comprise numerous neural units, some forming modules crucial for disease detection and targeted therapy.
• Accurate and effective identification of these neural unit modules is essential for clinical applications.

Purpose of the Study:

• To propose a novel algorithm, UFOA (Uniform design and Fruit Fly Optimization Algorithm), for accurate and effective analysis of brain networks to identify neural unit modules.
• To evaluate the performance of UFOA in detecting neural unit modules compared to existing methods.

Main Methods:

• The study integrates uniform design principles with the Fruit Fly Optimization Algorithm (FOA) to create the UFOA algorithm.
• UFOA is designed to achieve uniformly distributed feasible solutions and rapid convergence to the optimal solution.
• The algorithm's performance was validated using 37 resting-state functional MRI brain networks.

Main Results:

• UFOA demonstrated superior performance in terms of modularity compared to five other methods.
• The algorithm showed comparable performance in terms of conductance against the same five methods.
• Comparative analysis confirmed that incorporating uniform design significantly benefits the UFOA algorithm's performance.

Conclusions:

• UFOA is an effective and superior method for identifying neural unit modules in brain networks.
• The integration of uniform design with FOA enhances the algorithm's ability to find optimal solutions efficiently.
• The findings suggest UFOA's potential utility in disease detection and targeted therapy through improved brain network analysis.
