Introduction

The emergence of smart cities represents a transformative shift in urban management, fueled by the integration of advanced technologies and data-driven solutions [1]. As urban populations continue to grow, cities are becoming increasingly complex ecosystems that demand innovative approaches for efficient management and sustainability [2]. Machine learning (ML) and deep learning (DL) algorithms have become critical enablers in addressing these complexities by enabling cities to process, analyze, and leverage vast amounts of real-time data generated by various sources, including sensors, Internet of Things (IoT) devices, and digital platforms [3]. These algorithms have the potential to optimize decision-making processes across multiple urban domains, from traffic management to resource distribution, public safety, and environmental monitoring, ultimately improving the quality of life for urban residents [4]. The widespread adoption of these technologies introduces a range of challenges, particularly in areas related to data integration, system scalability, real-time performance, and ethical considerations [5].

Real-time data processing is a cornerstone of smart city operations, and ML and DL algorithms are uniquely positioned to handle this challenge [6]. Smart cities generate an enormous volume of data at an ever-increasing rate, requiring advanced analytics to make timely and informed decisions [7]. For instance, real-time traffic monitoring systems rely on ML algorithms to predict traffic flow patterns and optimize signal timings, reducing congestion and enhancing mobility [8]. Similarly, DL models are employed in environmental monitoring to predict air quality levels, identify potential hazards, and recommend corrective actions. The ability to process and analyze data in real-time ensures that smart cities can respond to dynamic conditions quickly, facilitating better resource allocation, minimizing delays, and enhancing the efficiency of urban services [9]. Despite the promise of these technologies, the complexity and scale of data generated by smart cities necessitate continuous advancements in machine learning and deep learning techniques to ensure real-time decision-making remains effective and efficient [10].
