    In the first scenario, experiments are conducted on total 20 features using three different classifiers, i.e., SVM, NB, and RF with k-fold cross validation (k = 10) without using CAGA. According to the bar chart in Fig. 7, the accuracy, sensitivity, specificity, and F-Measure for each of the given classifier, i.e., SVM, NB, and RF, are determined for the evaluation of their performances. It can be observed from Fig. 7, that the average performance results of ac-curacy, sensitivity, specificity, and F-Measure are 93.99%, 96.22%, and 94.10%, achieved for SVM, NB, and RF classifier, respectively. In the second scenario, CAGA based feature optimization is applied during experimentation, where 6 optimal features are selected out of a total 20 features for classification purpose. The optimal features such as Feret y , Feret angle, Min-Feret, Aspect Ratio, Roundness, and Solidity are extracted and used in three different classifiers, i.e., SVM, NB, and RF, for the classification with cross-validation of 10-fold. It can be observed from Fig. 8 that using CAGA based selected features, the average perfor-mance results of accuracy, sensitivity, specificity, and F-Measure are 95.99%, 1032350-13-2 98.80%, and 93.25%, achieved for SVM, NB, and RF classifier, respectively.
    The classification results obtained in both scenarios, i.e., with or without CAGA, indicates the advantage of CAGA over non-CAGA in the classification of malignant cells. From Figs. 7 and 8, it can be observed that in both scenarios the NB classifier performs better than SVM and RF due to its high ratio in accuracy, sensitiv-ity, specificity and F-Measure. Therefore, by applying the majority voting algorithm, NB is the best classifier for the malignant 1032350-13-2 detection in breast cytology images.
    4. Conclusion
    In this paper, we have proposed a framework for an e-Health care service to efficiently and accurately detect and classify ma-lignant cells in breast cancer in breast cytology images. In the proposed framework, state-of-the-art CAGA technique is used for the optimal selection of features from different shape based and textured based features to increase the classification accuracy
    and reduce the computational complexity. Similarly, three well-known classification techniques, i.e., SVM, NB, and RF, are applied to classify tumor cells into malignant and benign. The results obtained using real data sets during experimentation validate the classification accuracy up to 98% for NB as compared to SVM and RF. In future, the proposed framework will be improved by incor-porating deep learning techniques in cloud-based e-Health care servers supporting IoMT for the accurate classification of other medical diseases, which can assist medical physicians efficiently and accurately to make more intelligent decisions in diagnosing breast cancer.
