Efficient multimodal deep-learning-based COVID-19 diagnostic system for noisy and corrupted images

Abstract

Introduction In humanity’s ongoing fight against its common enemy of COVID-19, researchers have been relentless in finding efficient technologies to support mitigation, diagnosis, management, contact tracing, and ultimately vaccination. Objectives Engineers and computer scientists have deployed the potent properties of deep learning models (DLM) in COVID-19 detection and diagnosis. However, publicly available datasets are often adulterated during collation, transmission, or storage. Meanwhile, inadequate, and corrupted data are known to impact the learnability and efficiency of DLMs. Methods This study focuses on enhancing previous efforts via two multimodal diagnostic systems to extract required features for COVID-19 detection using adulterated chest X-ray images. Our proposed DLM consists of a hierarchy of convolutional and pooling layers that combine to support efficient COVID-19 detection using chest X-ray images. Additionally, a batch normalization layer is used to curtail overfitting that usually arises from the convolution and pooling (CP) layers. Results In addition to match the performance of standard techniques reported in the literature, our proposed diagnostic systems attain an average accuracy of 98% in the detection of normal, COVID-19, and viral pneumonia datasets using corrupted and noisy images. Conclusions Such robustness is crucial for real-world applications where data is usually unavailable, corrupted, or adulterated.

Combating the COVID-19 infodemic using Prompt-Based curriculum learning

“…One problem we encountered was the sparsity of some classes due to a medium-size data set, making it difficult to classify tweets accurately; to overcome this limitation, we plan to investigate few-short or zero-shot learning methods to handle the data sparsity issue. We also intend to explore semi-supervised and unsupervised algorithms to address the issue ( Hammad et al, 2022 , Nagi et al, 2022 ). In addition, our proposed method can only be applied to the COVID-19 infodemic in English, and building a new model from scratch for a new language can be time-consuming and resource-intensive.…”

Ensemble learning for multi-class COVID-19 detection from big data

“…Machine Learning has garnered widespread recognition across multiple domains due to its ability to convert raw data into valuable insights, predictions, and decision-making tools. This versatility and compatibility across various fields have established Machine Learning as a pivotal technology in contemporary research and development [ 10 ].…”

“…By contrast, Data Science and Machine Learning practices have solved numerous longstanding multifarious problems [9,10]. There is no prospect that Data Science and Machine Learning methods will instantaneously resolve COVID-19.…”

Machine learning applications for COVID-19 outbreak management

“…Many of the most prominent ML approaches are described in the context of combating the epidemic [51]. Also, SVM is a strong technique for dealing with regression and classification issues [52], because of its excellent accuracy and performance have been used in various real-world applications, including the health industry [53]. Furthermore, one of the main strategies is RF, which is a statistical method used to deal with classification and regression challenges [54].…”
