What's Happening?
A novel approach for breast cancer detection has been developed using a Nesterov accelerated adam optimizer combined with an attention mechanism. The study utilized the BUSI dataset, which includes breast ultrasound images from 600 women, to train and evaluate machine learning models. The research focused on improving classification accuracy through preprocessing techniques such as denoising, normalization, and augmentation. The Nadam optimizer demonstrated superior performance compared to other optimizers, achieving high accuracy, sensitivity, specificity, and AUC scores. The study also highlighted the importance of preprocessing in enhancing model performance and generalizability.
