In this work, Akira Horiguchi investigates alternatives to the usual split-count variable activity metrics.  Building on the idea of Sobol indices, Akira finds that the popular split-count can, in fact, be quite misleading.  Subsequently, an efficient algorithm for computing such indices in BART models is developed and an interesting connection to the usual split-count metric is described.  We will be adding this feature to the OpenBT code base over the next few months!  <a href=\"https:\/\/arxiv.org\/abs\/2005.13622\">https:\/\/arxiv.org\/abs\/2005.13622<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Our latest BART paper, &#8220;Assessing variable activity for Bayesian regression trees,&#8221; has been posted to arXiv!
