Topological Representations of Local Explanations

no code implementations6 Jan 2022 Peter Xenopoulos, Gromit Chan, Harish Doraiswamy, Luis Gustavo Nonato, Brian Barr, Claudio Silva

Furthermore, due to the stochastic nature of some explainability methods, it is possible for different runs of a method to produce contradictory explanations for a given observation.

Counterfactual Explanations via Latent Space Projection and Interpolation

no code implementations2 Dec 2021 Brian Barr, Matthew R. Harrington, Samuel Sharpe, C. Bayan Bruss

Counterfactual explanations represent the minimal change to a data sample that alters its predicted classification, typically from an unfavorable initial class to a desired target class.
