Osvaldo Martin

Osvaldo Martin is a researcher at CONICET, in Argentina. He has experience using Markov Chain Monte Carlo methods to simulate molecules and perform Bayesian inference. He loves to use Python to solve data analysis problems. He is especially motivated by the development and implementation of software tools for Bayesian statistics and probabilistic modeling. He is an open-source developer, and he contributes to Python libraries like PyMC, ArviZ and Bambi among others. He is interested in all aspects of the Bayesian workflow, including numerical methods for inference, diagnosis of sampling, evaluation and criticism of models, comparison of models and presentation of results.

9.6 Summary

BART is a flexible non-parametric model where a sum of trees is used to approximate an unknown function from the data. Priors are used to regularize inference, mainly by restricting trees’ learning capacity so that no individual tree is able to explain the data, but rather the sum of trees. PyMC-BART is a Python library that extends PyMC to work with BART models.

We built a few BART models in this chapter, and learned how to perform variable selection and use partial dependence plots and individual conditional plots to interpret the output of BART models.
