Local Universal Explainer (LUX) -- a rule-based explainer with factual, counterfactual and visual explanations

1 code implementation23 Oct 2023 Szymon Bobek, Grzegorz J. Nalepa

We tested our method on real and synthetic datasets and compared it with state-of-the-art rule-based explainers such as LORE, EXPLAN and Anchor.

DeepVATS: Deep Visual Analytics for Time Series

1 code implementation8 Feb 2023 Victor Rodriguez-Fernandez, David Montalvo, Francesco Piccialli, Grzegorz J. Nalepa, David Camacho

DeepVATS trains, in a self-supervised way, a masked time series autoencoder that reconstructs patches of a time series, and projects the knowledge contained in the embeddings of that model in an interactive plot, from which time series patterns and anomalies emerge and can be easily spotted.

Enhancing Cluster Analysis With Explainable AI and Multidimensional Cluster Prototypes

1 code implementation IEEE Access 2022 Szymon Bobek, Michal Kuk, Maciej Szelążek, Grzegorz J. Nalepa

In most cases, such application is based on the transformation of an unsupervised clustering task into a supervised one and providing generalised global explanations or local explanations based on cluster centroids.

KnAC: an approach for enhancing cluster analysis with background knowledge and explanations

1 code implementation16 Dec 2021 Szymon Bobek, Michał Kuk, Jakub Brzegowski, Edyta Brzychczy, Grzegorz J. Nalepa

We argue that this can be the bottleneck in the process, especially in cases where domain knowledge exists prior to clustering.
