Cabanas-Tirapu, O., Danús, L., Moro, E. et al. Human mobility is well described by closed-form gravity-like models learned automatically from data. Nat Commun

Objective:

  • Compare the performance at predicting mobility flows of simple gravity models, complex machine learning and deep-learning methods, and closed-form, interpretable models obtained through Bayesian symbolic regression

Case:

  • Six states, US

Methodology:

  • Flow prediction:
    • Bayesian machine scientist
    • Gravity model
    • Radiation model
    • Random forest
    • Deep gravity

Data Source

  • Mobile phone

Findings:

  • Automated equation discovery approaches lead to parsimonious closed-form models that combine the most desirable aspects
