Researchers have developed the Spectral Model eXplainer (SMX), a new framework designed to improve the explainability of machine learning models used in chemometrics and spectroscopy. Unlike existing methods that focus on individual variables, SMX analyzes chemically meaningful spectral zones. The framework uses PCA to summarize zones, estimates predicate relevance through subsampling, and aggregates rankings using a directed weighted graph. SMX was tested on eight real-world spectral datasets, including those from X-ray Fluorescence and Gamma-ray Spectrometry. AI
