Quently evaluated with all the classification model. The information acquired from the FTIR spectroscope was analyzed making use of the scikit-learn machine mastering library in Python. The radial basis function (RBF) was utilised because the kernel function of SVM utilizing the grid search technique. To add an further validation step to our model, we applied the confusion Bevacizumab Autophagy matrix for both multiclass datasets, as shown in Tables 7 and eight.
