McCarthy later defined AI as “the science and engineering of making intelligent machines, especially intelligent computer programs,” which emphasizes the broad nature of the field that seeks to enable machines to achieve goals through computational decision-making[1][2].

Throughout the decades, AI has undergone significant transformations, evolving from theoretical concepts to practical applications. In 1959, AI researcher Arthur Samuel coined the term “machine learning” to describe programs capable of learning from experience. This marked a pivotal moment in the field, laying the groundwork for the development of algorithms that would enable machines to improve their performance over time through data[2].

As technology progressed, traditional machine learning relied heavily on centralized servers to process vast amounts of data sourced from the internet. However, the advent of edge computing shifted this paradigm, allowing for data processing closer to the source—namely, on devices like smartphones and embedded systems. This approach not only reduced latency and bandwidth usage but also enhanced the speed and efficiency of data processing, which became particularly beneficial in time-sensitive sectors such as healthcare[3][4].

In recent years, the rise of Tiny Machine Learning (TinyML) has further revolutionized the field by enabling the deployment of lightweight machine learning models on

low-power devices, such as microcontrollers and sensors. This trend signifies a move towards more efficient and accessible AI solutions that can operate in real-time without the need for continuous internet connectivity, thus addressing some of the limitations associated with traditional AI implementations[7][8].

One of the primary challenges in deploying Edge AI and TinyML solutions is the limitation on computational resources. Edge devices typically have restricted computational power, memory, and storage when compared to cloud-based servers, which necessitates careful optimization of machine learning models to operate efficiently within these constraints[10]. This often requires trade-offs between model complexity and resource efficiency, leading to potential compromises in model accuracy[11].

Additionally, achieving robust model performance in dynamic and unpredictable environments remains a considerable challenge for developers[11].

Power Efficiency

Power consumption is another critical issue, particularly for battery-powered edge devices such as wearables and IoT sensors. These devices must be designed to minimize energy usage to ensure extended operation without frequent recharging[- 22]. For instance, while ideal conditions may predict a battery life of over ten years, actual implementations frequently reveal much shorter lifespans due to high power consumption rates[22]. Balancing the complexity of models with power efficiency is essential for the viability of TinyML applications, as excessive power demands can lead to rapid depletion of device batteries[25][22].

As more data processing occurs at the edge, ensuring data privacy and security becomes increasingly important. With the rise of personal data protection regulations such as GDPR and CCPA, maintaining compliance while leveraging local processing is crucial[26]. Edge devices that process sensitive information locally can significantly enhance user trust by mitigating the need to transmit personal data over the internet, thus reducing the risk of data breaches[26]. However, the security of data stored and processed at the edge remains a concern, as many devices lack robust security measures, leading to vulnerabilities[27][28].

Development Complexity

The development and optimization of models suitable for edge deployment can be complex and time-consuming. It often requires specialized expertise in both machine learning and embedded systems[11]. Furthermore, the lack of established research on security and privacy in the context of TinyML applications underscores the need for ongoing exploration and analysis to address these emerging concerns effectively[27][28].
