A Dirichlet Process Mixture Model of Discrete Choice
Rico Krueger, Akshay Vij, Taha H. Rashidi
We present a mixed multinomial logit (MNL) model, which leverages the truncated stick-breaking process representation of the Dirichlet process as a flexible nonparametric mixing di…
Machine Learning Meets Microeconomics: The Case of Decision Trees and Discrete Choice
Timothy Brathwaite, Akshay Vij, Joan L. Walker
We provide a microeconomic framework for decision trees: a popular machine learning method. Specifically, we show how decision trees represent a non-compensatory decision protocol…
Modeling and Forecasting the Evolution of Preferences over Time: A Hidden Markov Model of Travel Behavior
Feras El Zarwi, Akshay Vij, Joan Walker
Literature suggests that preferences, as denoted by taste parameters and consideration sets, may evolve over time in response to changes in demographic and situational variables, p…
A Discrete Choice Framework for Modeling and Forecasting The Adoption and Diffusion of New Transportation Services
Feras El Zarwi, Akshay Vij, Joan Walker
Current travel demand models are unable to predict long-range trends in travel behavior as they do not entail a mechanism that projects membership and market share of new modes of…
