Schematic representation of experimental methodology. Initially input data is preprocessed to generate the dataset to be employed to further establish a CNN model. In parallel, patient metadata variable is also preprocessed to generate dataset for establishing the ANN model. These independent models were further combined to assess the impact on accuracy of the prediction between image only data (CNN model) and image plus patient’s metadata (CNN+ANN model).
