Automatic Detection and classification of Correct placement of tubes on chest X-rays using deep learning with EfficientNet

In recent years, the rapid growth of data in healthcare has prompted a lot of interest in artificial intelligence (AI). Powerful AI algorithms are essential for extracting information from medical data and assisting clinicians in establishing quick and accurate diagnoses of a variety of ailments. In the current COVID-19 outbreak, critically ill patients were intubated and various medical tubes, including an endotracheal tube (ETT), were implanted to protect the airways. The Nasogastric tube (NGT) is used for feeding, whereas the Central Venous Catheter (CVC) is utilized for a variety of medical operations. The adoption of medical protocols by doctors to ensure proper tube installation is a major issue. Manual examination of CXR pictures takes time and frequently leads to misinterpretation. This research aims to create an Automated Medical Tube Detection System that can detect misplaced tubes from chest x-rays (CXR) using deep learning. As a result, using chest x-rays to detect poorly positioned tubes can save lives. On CXR the proposed CNN-based EfficientNet architecture efficiently detects and classifies incorrectly positioned tubes. After detailed experimentation, we were able to achieve 0.95 average area under the ROC curve (AUC). © 2022 IEEE.

TM-BERT: A Twitter Modified BERT for Sentiment Analysis on Covid-19 Vaccination Tweets

In transfer learning a model is pre-trained on a large unsupervised dataset and then fine-tuned on domain-specific downstream tasks. BERT is the first true-natured deep bidirectional language model which reads the input from both sides of input to better understand the context of a sentence by solely relying on the Attention mechanism. This study presents a Twitter Modified BERT (TM-BERT) based upon Transformer architecture. It has also developed a new Covid-19 Vaccination Sentiment Analysis Task (CV-SAT) and a COVID-19 unsupervised pre-training dataset containing (70K) tweets. BERT achieved (0.70) and (0.76) accuracy when fine-tuned on CV-SAT, whereas TM-BERT achieved (0.89), a (19%) and (13%) accuracy over BERT. Another enhancement introduced is in terms of time efficiency as BERT takes (64) hours of pre-training while TM-BERT takes only (17) hours and still produces (19%) improvement even after pre-trained on four (4) times fewer data. © 2022 IEEE.
