Comparative evaluation for alternative variable importance rankings for pedestrian injury severities
Abstract Little research is dedicated to evaluating the performance difference of various metrics in ranking predictor importance traffic safety field. To this end, main objective current paper evaluate and quantify different methods for sorting variable related crash severity. A comprehensive database pedestrian-related crashes state California was developed. Four popular measurement used past...
Quantitative histomorphometry is the process of modeling appearance of disease morphology on digitized histopathology images via image-based features (e.g., texture, graphs). Due to the curse of dimensionality, building classifiers with large numbers of features requires feature selection (which may require a large training set) or dimensionality reduction (DR). DR methods map the original high...
Relative importance of regressor variables is an old topic that still awaits a satisfactory solution. When interest is in attributing importance in linear regression, averaging over orderings methods for decomposing R2 are among the state-of-theart methods, although the mechanism behind their behavior is not (yet) completely understood. Random forests—a machinelearning tool for classification a...
