This study utilizes the Breast Ultrasound Image (BUSI) dataset to present a deep learning technique for breast tumor segmentation based on a modified UNet architecture. To improve segmentation accuracy, the model integrates attention mechanisms, such as the Convolutional Block Attention Module (CBAM) and Non-Local Attention, with advanced encoder architectures, including ResNet, DenseNet, and EfficientNet. These attention mechanisms enable the model to focus more effectively on relevant tumor areas, resulting in significant performance improvements.

In this study, it is aimed to generate improved models for detecting undiagnosed type II diabetes mellitus patients by employing data from both undiagnosed and diagnosed patients. The main motivation is that, with the widespread use of electronic health records, increasing amount of data is accumulating for diagnosed patients. In our simulations, the training sets are allowed to include data from both undiagnosed and diagnosed patients.
