Project Title: Provide Data Visualization Health Guidance by Modelling and Optimizing Dietary Intake Student: Shuo Xu Course: MSc in Computer Science Abstract: This report establishes a food intake optimization model to provide dietary guidance to British people who are grouped by gender and age. The method proposed in this project is based on the linear optimization method and implemented in the R language. Compared with the related works, the proposed method is different from the linear optimization software used in the mainstream and is better at processing large amounts of data and visualizing results. Also, this method is programmed which means it would be easier to set various linearization settings and implement complex optimization functions in the optimization process. After the optimized results obtained by the optimization method, this project analyzes the output data through data visualization technology which could provide more specific and easier to understand guidance for different target groups.
