Regularized impurity reduction: Accurate decision trees with complexity guarantees
Guangyi Zhang, Aristides Gionis
Decision trees are popular classification models, providing high accuracy and intuitive explanations. However, as the tree size grows the model interpretability deteriorates. Tradi…
Ranking with submodular functions on a budget
Guangyi Zhang, Nikolaj Tatti, Aristides Gionis
Submodular maximization has been the backbone of many important machine-learning problems, and has applications to viral marketing, diversification, sensor placement, and more. How…
Coresets remembered and items forgotten: submodular maximization with deletions
Guangyi Zhang, Nikolaj Tatti, Aristides Gionis
In recent years we have witnessed an increase on the development of methods for submodular optimization, which have been motivated by the wide applicability of submodular functions…
