Outline

This paper presents a novel approach to the Discrete Choice Model (DCM), which is essential for modeling human decision-making processes, called the Differentiable Discrete Choice Model (Diff-DCM). While conventional DCMs heavily rely on domain knowledge from experts, Diff-DCM can automatically learn, predict, and control interpretable models based on data through differential programming. It estimates an interpretable closed-form utility function that reproduces observed behaviors with only input features and choice outcomes without prior knowledge, and experiments on synthetic and real data show that it is applicable to various types of data and can be estimated quickly with a small amount of computational resources. In addition, it shows that differentiability can be utilized to provide insights such as optimal intervention paths for effective behavior change.

Takeaways, Limitations

Takeaways:
We present a novel approach to automate and interpret data-driven discrete choice modeling.
Predict and control human behavior by estimating utility functions without prior knowledge.
Fast estimation with limited computational resources (within tens of seconds on a laptop).
Using differentiability to provide insights into human behavior (e.g., optimal intervention paths).
Applicable to various types of data.
Limitations:
Further verification of the generalizability of the experimental results presented in this paper is needed.
Further research is needed on how sensitive the model's performance is to the quality of the data.
Further analysis of the model's Limitations is needed to fully capture complex human behavior.
Further research is needed on the applicability and constraints for various types of discrete choice models.
