RT Conference Proceedings T1 On the role of relations and interactions in fuzzy systems for machine learning A1 Pérez-Sechi, Carlos Ignacio A1 Gutiérrez García-Pardo, Inmaculada A1 Castro Cantalejo, Javier A1 Gómez González, Daniel A1 Martín García, Daniel A1 Espínola Vílchez, María Rosario AB In this study, we address the challenge of explainability in machine learning within the context of multi-agent fuzzy systems. Specifically, we present two advances. On one hand, based on the Kruskal-Wallis test, we define the KWSHAP algorithm, which is applicable to any machine learning model. On the other hand, we introduce a method to define variables in a machine learning model when the input includes several fuzzy measures defined over a set of agents. This information is incorporated into the model through the calculation of the Shapley value and interaction indices. The KWSHAP algorithm and the subsequent graph representation allow us to interpret the role and importance of these interactions. Our findings enhance machine learning interpretability, offering a statistically robust and flexible framework for understanding relationships among features, thus contributing to more transparent and trustworthy decision-making processes SN 1544-5615 YR 2025 FD 2025 LK https://hdl.handle.net/20.500.14352/132205 UL https://hdl.handle.net/20.500.14352/132205 LA eng NO C.
