Graduation project: Graphical Models To Represent Consumer Behavior

About the project
The goal of this project is to represent a very high-dimensional data set with a graphical model (a Bayesian network or a Markov random field). The data is derived from a survey in which respondents voluntarily answer a large questionnaire. The questionnaire includes questions on leisure activities, purchase behaviors, demographics, social media and more (as illustrated below). The total number of variables obtained from the data is about 10,000. The yearly sample size for the questionnaire is about 50,000. Working on this project, you will help us to reproduce not only the marginals of the multivariate distribution, but also the covariance structure.
Examples of queries we would like the network to answer are:
• From those who are watching sports programs on TV, who is also visiting sport websites?
• What percentage of TV programs are people between 20 and 30 viewing online?
• What is the composition of people following a diet by age, gender and education? How does that vary across different type of diets?
