Introduction

NAS has emerged as a pivotal advancement in the field of machine learning, revolutionizing the way neural network architectures are designed and optimized [1]. As the complexity of machine learning models increases, traditional manual design methods have proven insufficient for meeting the demands of modern applications [2]. NAS offers a systematic approach to discovering optimal neural network architectures by automating the search process, thus enabling the creation of models that outperform manually engineered counterparts [3]. This introduction explores the fundamental concepts of NAS, its methodologies, and its impact on various domains [4,5].

At its core, NAS involves the automated exploration of architecture spaces to identify neural network designs that yield superior performance. Traditional methods for designing neural networks often rely on expert knowledge and heuristic approaches, which can be both time-consuming and limited in scope [6]. In contrast, NAS leverages algorithms such as reinforcement learning and evolutionary strategies to efficiently search through a vast space of potential architectures [7]. These algorithms iteratively refine the search process based on performance metrics, enabling the discovery of highly effective network designs that not be apparent through manual methods [8].
