Accurate segmentation of breast tissue in ultrasound images is crucial for the early detection and analysis of breast cancer. Traditional approaches to medical image segmentation often rely on manually designed neural network architectures, which can be time-consuming and dependent on expert knowledge. In this study, we propose a novel approach that combines Neural Architecture Search (NAS) with a genetic algorithm to optimize the UNet deep neural network for breast tissue segmentation. This combination leverages the strengths of both NAS and evolutionary algorithms to enhance model performance and enable the automated design of efficient architectures. Experimental results demonstrate that our proposed approach is both effective and efficient in optimizing hyperparameters. The automatically constructed UNet models are competitive with manually designed architectures in terms of segmentation accuracy and computational efficiency. The GNAS-UNet model is utilized on the Breast Ultrasound Image Dataset (BUSI). The experimental findings demonstrate competitive performance, achieving an overall DC of 0.937, Miou of 0.906, demonstrating the competitiveness of automated architectures with manually crafted ones. Furthermore, the genetic algorithm's ability to navigate the search space results in the discovery of suitable network configurations that generalize well to new data. Our results underscore the potential of automated machine learning techniques in advancing the accuracy and efficiency of medical image segmentation tasks. One of the primary objectives of this study is to reduce the design time and provide an efficient approach for building optimal architectures.
