Fas-xai: An interpretable framework for the comparative morphological analysis of lunar and martian impact craters. Mathematics, 14(9), 1445. https://doi.org/10.3390/math140914452227-7390https://hdl.handle.net/11268/17087Impact craters are among the most abundant geological structures on solid planetary surfaces and provide valuable information about impact processes and surface evolution. However, the systematic characterization of crater morphology remains challenging due to dataset heterogeneity, measurement uncertainty, and gradual transitions between morphological classes. This study proposes FAS-XAI, an interpretable framework for the comparative analysis of planetary crater datasets that combines fuzzy clustering and explainable artificial intelligence (XAI). The methodology combines exploratory data analysis, measurement-uncertainty assessment, unsupervised learning, supervised consistency analysis, and interpretable machine learning to identify and characterize crater morphologies through a structured workflow.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Computación y tecnologíajournal article10.3390/math14091445open accessInteligencia artificialLógica matemáticaAstronomíaGoal 9: Build resilient infrastructure, promote sustainable industrialization and foster innovation
