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…
Causal Inference in Travel Demand Modeling (and the lack thereof)
Timothy Brathwaite, Joan Walker
This paper is about the general disconnect that we see, both in practice and in literature, between the disciplines of travel demand modeling and causal inference. In this paper, w…
Asymmetric, Closed-Form, Finite-Parameter Models of Multinomial Choice
Timothy Brathwaite, Joan L. Walker
In transportation, the number of observations associated with one discrete outcome is often greatly different from the number of observations associated with another discrete outco…
