- Abstract
The term variable importance refers to the role of an attribute in making accurate predictions. A particular model, when relies majorly on multiple variables, increases variable importance of those variables in positive direction. Variable importance is applied to various classification and regression models using different methods. For example, in regression model, higher value Root Mean Squared Error (RMSE) is the indicator of high importance to that variable, whereas in classification model, higher number of splits associated with a variable determines its importance in the model. In this research study, we have considered a problem of road surface classification depending upon 17 variables associated with vehicle parameters. This is a multiclass classification problem. Different classification and regression models are used, and variable importance of each model is evaluated on the metrics like RMSE, Goodness of fit model. Outcome of this research study shows all models define a common set of 5 to 7 higher importance variable rankings to predict dependant variable.
