Abstract In this research we have explored effectiveness of autoencoder in anomalous detection, deep learning models in image classification and Grad-CAM in Explanation of classification and detection. We mainly focused on classifying
Tuberculosis and Pneumonia. We collected normal, Tuberculosis and Pneumonia chest X-ray images from publicly available Kaggle dataset. Our research constitutes of two stages. In stage 1, We trained Autoencoder on only one class i.e., normal chest X-ray images. Thus, making the model more effective in detecting anomaly in a chest X-ray image if it is having anomalous pattern compared to normal image. If the model detects any anomaly it is directed to stage 2 where the deep learning models i.e., InceptionV3 and Xception are trained on Tuberculosis and Pneumonia chest X-ray images. These models are integrated with Grad-CAM to generate heatmap that detects and visualizes disease spot in the test image. These models are evaluated on training and testing accuracies. Xception model has achieved an accuracy of 100 % while InceptionV3 achieved an accuracy of 99.77%. The Integration of Grad-CAM made it easier to interpret and trust the model’s decision-making process.
