Abstract	Artificial Intelligence (AI) and Machine Learning (ML) are transforming industries such as healthcare, finance, transportation, and the Internet of Things (IoT). However, training high-performing ML models requires massive datasets, often containing sensitive personal information. The traditional paradigm of centralized data aggregation raises critical privacy, security, and regulatory concerns. Federated Learning (FL) has emerged as a disruptive framework that enables collaborative model training across multiple decentralized devices or organizations without exchanging raw data. This paper presents a comprehensive study of federated learning, detailing its architecture, key algorithms, privacy-preserving mechanisms, and real-world applications. We evaluate FL performance on benchmark datasets and discuss technical challenges, including non-IID (non-independent and identically distributed) data, communication bottlenecks, and adversarial threats. Experimental results show that FL achieves near-centralized accuracy with significantly enhanced privacy guarantees, making it a promising candidate for privacy-sensitive AI systems. Future research directions are proposed, including hybrid FL-blockchain models, efficient communication strategies, and secure aggregation protocols.
