[email protected] Abstract—With the breakthrough performance in a variety of attracting wide attentions [7]–[14], which also achieve the computer vision and medical image analysis problems, convolu- breakthrough performance compared to traditional machine tional neural networks (CNNs) have been successfully introduced learning models. Generally speaking, CNN methods for breast for the classification task of breast cancer histopathological images in recent years. Nevertheless, existing breast cancer cancer pathological images classification can be divided into histopathological image classification networks mainly utilize the three categories as follows. Firstly, some researchers utilize first-order statistic information of deep features to represent representative or newly constructed CNNs as feature extractors histopathological images, failing to characterize the complex followed by traditional classifiers to distinguish the extracted
