Learning from Logical Constraints with Lower- and Upper-Bound Arithmetic Circuits

IJCAI 2025

An important class of neuro-symbolic (NeSy) methods relies on knowledge compilation (KC) techniques to transform logical constraints into a differentiable exact arithmetic circuit (AC) that represents all models of a logical formula. However, given the complexity of KC, compiling such exact circuits

Learning Optimal Decision Trees using Constraint Programming (Extended Abstract)

IJCAI 2020poster

Decision trees are among the most popular classification models in machine learning. Traditionally, they are learned using greedy algorithms. However, such algorithms have their disadvantages: it is difficult to limit the size of the decision trees while maintaining a good classification accuracy, a…
