Classification of Chest X-Ray Images Using Modern Machine Learning Techniques by Orang3 Data Mining Tool

During the COVID-19 pandemic, there were many concerns raised in diagnosing chest diseases. Regular diagnosis processes of chest diseases sometimes fail in distinguishing between Corona, viral pneumonia diseases, and normal chest x-rays through regular assessments which also need time and not as accurate as the automated diagnosis based on machine learning. Chest diseases can be sometimes diagnosed using x-ray images where these images are used to identify if the patient is normal or has one of the chest diseases like Corona and viral pneumonia. Modern machine learning techniques have achieved high performance in aiding medical diagnostic processes. The novelty of this work lies in a wavelet-based feature extraction framework coupled with a systematic evaluation of ensemble learning algorithms for accurate and computationally efficient classification of COVID-19, viral pneumonia, and normal chest x-ray images. The number of patients used in each case is 1200 patients and this huge dataset is used to create classification models using adaptive boosting (AdaBoost), gradient boosting (GB), and random forest (RF) machine learning algorithms using Orange3 data mining tool. Using wavelet features, the results of evaluating the proposed models were 99.5% on average. The proposed models are very effective in identifying chest diseases and can be combined with x-ray machines in hospitals, so physicians can determine the best treatment for patients. The proposed methods beat other researchers found in literature as they are faster and more accurate where each step takes few seconds on average to complete.
