Feasible and Desirable Counterfactual Generation by Preserving Human Defined Constraints

no code implementations12 Oct 2022 Homayun Afrabandpey, Michael Spranger

Through user studies, we demonstrate that incorporating causal constraints during CF generation results in significantly better explanations in terms of feasibility and desirability for participants.

A Decision-Theoretic Approach for Model Interpretability in Bayesian Framework

1 code implementation21 Oct 2019 Homayun Afrabandpey, Tomi Peltola, Juho Piironen, Aki Vehtari, Samuel Kaski

Through experiments on real-word data sets, using decision trees as interpretable models and Bayesian additive regression models as reference models, we show that for the same level of interpretability, our approach generates more accurate models than the alternative of restricting the prior.

Interactive Prior Elicitation of Feature Similarities for Small Sample Size Prediction

no code implementations8 Dec 2016 Homayun Afrabandpey, Tomi Peltola, Samuel Kaski

The key idea is to use an interactive multidimensional-scaling (MDS) type scatterplot display of the features to elicit the similarity relationships, and then use the elicited relationships in the prior distribution of prediction parameters.

Visualizations Relevant to The User By Multi-View Latent Variable Factorization

no code implementations24 Dec 2015 Seppo Virtanen, Homayun Afrabandpey, Samuel Kaski

The factorization is a generative model in which the display is parameterized as a part of the factorization and the other factors explain away the aspects not expressible in a two-dimensional display.
