Calibrated Explanations for Regression

1 code implementation30 Aug 2023 Tuwe Löfström, Helena Löfström, Ulf Johansson, Cecilia Sönströd, Rudy Matela

This paper introduces an extension of a feature importance explanation method, Calibrated Explanations (CE), previously only supporting classification, with support for standard regression and probabilistic regression, i. e., the probability that the target is above an arbitrary threshold.

Approximating Score-based Explanation Techniques Using Conformal Regression

no code implementations23 Aug 2023 Amr AlKhatib, Henrik Boström, Sofiane Ennadir, Ulf Johansson

The results also suggest that the proposed method can produce tight intervals, while providing validity guarantees.

Well-Calibrated Probabilistic Predictive Maintenance using Venn-Abers

no code implementations11 Jun 2023 Ulf Johansson, Tuwe Löfström, Cecilia Sönströd

In the experiments, we apply Venn-Abers calibration to decision trees, random forests and XGBoost models, showing how both overconfident and underconfident models are corrected.

Calibrated Explanations: with Uncertainty Information and Counterfactuals

1 code implementation3 May 2023 Helena Lofstrom, Tuwe Lofstrom, Ulf Johansson, Cecilia Sonstrod

While local explanations for AI models can offer insights into individual predictions, such as feature importance, they are plagued by issues like instability.

A Meta Survey of Quality Evaluation Criteria in Explanation Methods

no code implementations25 Mar 2022 Helena Löfström, Karl Hammar, Ulf Johansson

In this paper, we have conducted a semi-systematic meta-survey over fifteen literature surveys covering the evaluation of explainability to identify existing criteria usable for comparative evaluations of explanation methods.
