This paper explores the application of machine learning (ML) algorithms for predictive maintenance in 5G networks, emphasizing their capability to improve network reliability by predicting potential failures. It reviews existing literature on various ML models, such as decision trees and neural networks, discussing their advantages, challenges, and methodologies for implementation within network operations. The research highlights the importance of data collection, preprocessing, and model training in enhancing the efficacy of these algorithms, while also identifying areas for future improvement and research in ML-based predictive maintenance strategies.
