Assessing COVID-19 Vaccine Hesitancy via Sentiment Analysis: A Fine-Tuned Naive Bayes Classifier using Feature Engineering

Leave a Comment / Covid-19 / By

Abstract—The introduction of COVID-19 vaccines was met with scepticism and fear, amplified through social media plat- forms such as Twitter. This work investigates public sentiment regarding vaccines by creating a new, more accurate classifier for classifying COVID-19-related tweets by employing transfer learning of a pre-trained model, fine tuning the model with COVID-19-related data, and feature …

The Fear, Force and Freedom factors of the COVID-19 mobility restrictions in relation to aviation and road traffic air pollution in Greater London and the Scottish Highlands.

Leave a Comment / Earth Science, Environment / By

Author: Donald Campbell Abstract: This study examines the effect of the UK COVID-19 lockdown on nitrogen dioxide road traffic emissions and the potential change in carbon dioxide air traffic emissions based on airport usage. In doing so, it compares air quality in specific areas of Greater London and the Scottish Highlands, allowing insight into possible …

Identifying the Best Image Classification Algorithm for COVID-19 Diagnosis with a Small, Imbalanced Chest X-Ray Dataset

Leave a Comment / Covid-19 / By

Abstract With more than 82 million COVID-19 cases worldwide [1], automated chest radiograph interpretation could provide substantial benefit for efficient and accurate diagnosis of COVID-19 patients. In this project, families of deep learning neural networks are trained on publicly available chest X-ray datasets to identify the best image classification algorithm for automating the diagnosis of …

IN THE BOXING RING WITH COVID-19: How do we fight a virus?

Leave a Comment / Covid-19, Health / By

Grace En Xie1 Abstract The COVID-19 pandemic is the ongoing battle between humans and the virus SARS-CoV-2. SARS-CoV-2 attacks by infiltrating the human body, causing mild to deadly effects. The virus spreads through human transmission into the lungs, activating the immune system to help or harm. People around the world have worked to reduce SARS-CoV-2’s …

Using Bluetooth RSSI Values to Classify Proximity with Deep Neural Networks for COVID-19 Contact Tracing

2 Comments / Computer Science / By

Abstract The Radio Signal Strength Indication (RSSI) obtained by Bluetooth can be used to estimate the proximity and duration of an individual’s exposure to patients diagnosed with COVID-19. This is because as the RSSI signal becomes stronger with the help of an rf amplifier, it indicates a closer proximity. This proximity information can be used …
