Schematic presentation of workflow used to investigate the quality of ML models for reliable identification of sweat film appearance. A number of prominent models have been obtained with the various quality of classification. Each column on the SHAP chart represents a different LightGBM model, the row represents the top 20 features, and the color represents their importance. Each feature name have name pattern <wave length>_<domain>_<function>_ <channel (for frequency domain only)>.
