Explainable Augmented Intelligence and Deep Transfer Learning for Pediatric Pulmonary Health Evaluation

Biomedical Instrumentation is one of the fastest health emerging innovative technologies with proven contribution towards interdisciplinary medicine, it helps physicians to diagnose complex medical problems and provide treatment to patients precisely and safely. With this technological trend, explainable artificial intelligence, biomedical image processing and augmented intelligence can provide a tool that can help pediatricians, pulmonology and otolaryngology physicians, epidemiologists and pediatric practitioners to interpretably and reliably diagnose chronic and acute respiratory disorders in children, adolescents and infants. Unfortunately, the reliability of digital image processing for pulmonary disease diagnosis often depends on availability of large chest X-ray image datasets. This work presents a reliable interpretable deep transfer learning approach for pediatric pulmonary health evaluation regardless of the scarcity and limited annotated pediatric chest X-ray Image dataset sizes. This approach leverages a combination of computer vision tools and techniques to reduce child morbidity and mortality through predictive and preventive medicine with reduced surveillance risks and affordability in low resource settings. With open datasets, the deep neural networks classified the generated augmented images into 4 classes namely;Normal, Covid-19, Tuberculosis and Pneumonia at an accuracy of 97%, 97%, 70%, and 73% respectively with recall of 100% for Pneumonia and overall accuracy of 79% at only 10 epochs for both regular and transferred learning. © 2022 IEEE.

An Explainable AI Model for Interpretable Lung Disease Classification

In this paper, we develop a framework for lung disease identification from chest X-ray images by differentiating the novel coronavirus disease (COVID-19) or other disease-induced lung opacity samples from normal cases. We perform image processing tasks, segmentation, and train a customized Convolutional Neural Network (CNN) that obtains reasonable performance in terms of classification accuracy. To address the black-box nature of this complex classification model, which emerged as a key barrier to applying such Artificial Intelligence (AI)-based methods for automating medical decisions raising skepticism among clinicians, we address the need to quantitatively interpret the performance of our adopted approach using a Layer-wise Relevance Propagation (LRP)-based method. We also used a pixel flipping-based, robust performance metric to evaluate the explainability of our adopted LRP method and compare its performance with other explainable methods, such as Local Interpretable Model Agnostic Explanation (LIME), Guided Backpropagation (GB), and Deep Taylor Decomposition (DTD). © 2021 IEEE.
