    Transfer Learning Using Alexnet With Support Vector Machine for Breast Cancer Detection
    (2020) Abdulghani, Sema; Fadhil, Ahmed Freidoon; Gültekin, Seyfettin Sinan
    Breast cancer is one of the leading causes of women death worldwide currently. Developing a computer-aided diagnosis system for breast cancer detection became an interesting problem for many researchers in recent years. Researchers focused on deep learning techniques for classification problems, including Convolutional Neural Networks (CNNs), which achieved great success. CNN is a specific class of deep, feedforward network that has obtained attention from the research community and achieved great successes, especially in biomedical image processing. In this paper, deep feature extraction methods are used which with pre-trained CNN model to classify breast cancer histopathological images from the publically available (BreakHis dataset). The data set includes two classes, benign and malignant, with four different magnification factors. A patch strategy method proposed based on the extraction of image patches for training the CNN and the combination of these patches for classification. AlexNet model is considered in this work with patch strategy, and pre-trained AlexNet is used for fine-tuning the system. Then, the Support Vector Machine (SVM) was used to classify the obtained features.The evaluation results show that the pre-trained Alexnet with SVM classification and patch strategy yields the best accuracy. Accuracy between 92% and 96% was achieved using five-fold cross-validation technique for different magnification factors.
