Abstrakt: In recent decades, the integration of optimization methods and Machine Learning (ML) models has garnered significant attention within the research community. In the pursuit of establishing a symbiotic relationship between ML and optimization algorithms, this study focuses on the fusion of the African Vulture Optimization Algorithm (AVOA) - an optimization algorithm inspired by the foraging behavior of African vultures - with Deep Neural Networks (DNNs) - a prevalent model in ML for damage detection of a real large-scale bridge. In this research, AVOA, possessing a vast search space and the ability to autonomously adjust crucial parameters during the search process, such as flight velocity and learning rate, is employed to select informative features such as weight and biases of DNNs. This synergy allows the network to automatically adjust its potential. The technique is applied to a truss bridge, utilizing Finite Element Model (FEM) data that has been validated by real-world vibration measurements, resulting in precise damage identification even in the presence of white Gaussian noise. Evaluation criteria demonstrate enhanced accuracy and computational efficiency compared to the traditional neural network approach. [ABSTRACT FROM AUTHOR]
