Webformulation of the decision tree learning that associates a binary latent decision variable with each split node in the tree and uses such latent variables to formulate the tree’s empirical loss. Inspired by advances in structured prediction [23, 24, 25], we propose a convex-concave upper bound on the empirical loss.
