Query: Classification of Viral Pneumonia X-ray Images with the Aucmedi
  Framework   In this work we use the AUCMEDI-Framework to train a deep neural network to
classify chest X-ray images as either normal or viral pneumonia. Stratified
k-fold cross-validation with k=3 is used to generate the validation-set and 15%
of the data are set aside for the evaluation of the models of the different
folds and ensembles each. A random-forest ensemble as well as a
Soft-Majority-Vote ensemble are built from the predictions of the different
folds. Evaluation metrics (Classification-Report, macro f1-scores,
Confusion-Matrices, ROC-Curves) of the individual folds and the ensembles show
that the classifier works well. Finally Grad-CAM and LIME explainable
artificial intelligence (XAI) algorithms are applied to visualize the image
features that are most important for the prediction. For Grad-CAM the heatmaps
of the three folds are furthermore averaged for all images in order to
calculate a mean XAI-heatmap. As the heatmaps of the different folds for most
images differ only slightly this averaging procedure works well. However, only
medical professionals can evaluate the quality of the features marked by the
XAI. A comparison of the evaluation metrics with metrics of standard procedures
such as PCR would also be important. Further limitations are discussed.
