Applications of AI and Big Data Analytics in Obesity Research
The obesity epidemic has become a global public health issue. As artificial intelligence (AI) technologies profoundly transform our world, how can AI help promote a healthier lifestyle and prevent unhealthy weight gain? I will introduce our recent research projects that apply AI and big data analytics in obesity prevention and health promotion.
Some project highlights are:
• A scoping review of AI methodologies applied to obesity research;
• Build a neural network model to predict tweet sentiments toward soda taxes in the US;
• Build a computer vision model to automatically estimate calories and nutritional portfolios of edible nuts in a photo;
• Evaluate AI-powered chatbot’s responses to body image-related questions commonly raised by adolescents and young adults;
• Build a natural language processing model to identify and autocorrect exaggerated news headlines covering scientific findings;
• Build machine learning models to correct errors and biases in self-reported height and weight.
