Generating collective counterfactual explanations in score-based classification via mathematical optimization

1 code implementation19 Oct 2023 Emilio Carrizosa, Jasone Ramírez-Ayerbe, Dolores Romero Morales

By means of novel Mathematical Optimization models, we provide a counterfactual explanation for each instance in a group of interest, so that the total cost of the perturbations is minimized under some linking constraints.

On Clustering Categories of Categorical Predictors in Generalized Linear Models

no code implementations19 Oct 2021 Emilio Carrizosa, Marcela Galvis Restrepo, Dolores Romero Morales

We propose a method to reduce the complexity of Generalized Linear Models in the presence of categorical predictors.

Optimal randomized classification trees

no code implementations19 Oct 2021 Rafael Blanquero, Emilio Carrizosa, Cristina Molero-Río, Dolores Romero Morales

Our classifier can be seen as a randomized tree, since at each node of the decision tree a random decision is made.

Sparsity in Optimal Randomized Classification Trees

no code implementations21 Feb 2020 Rafael Blanquero, Emilio Carrizosa, Cristina Molero-Río, Dolores Romero Morales

In this paper, we propose a continuous optimization approach to build sparse optimal classification trees, based on oblique cuts, with the aim of using fewer predictor variables in the cuts as well as along the whole tree.
