For Implementing a support vector machine, we can use the caret or e1071 package etc. The principle behind an SVM classifier (Support Vector Machine) algorithm is to build a hyperplane separating data for different classes. The variable importance plot is obtained by growing some trees, > require(randomForest) > fit=randomForest(factor(Y)~., data=df) Then we can use simple functions Ranking the variable importance with the caret package After building a supervised learning model, we can estimate the importance of features. This estimation employs a sensitivity analysis to measure the effect on the output of a given model when the inputs are varied. # bonus - great package for fast variable importance library (mRMRe) ind <-sapply (titanicDF, is.integer) titanicDF [ind] <-lapply (titanicDF [ind], as.numeric) dd <-mRMR.data (data = titanicDF) feats <-mRMR.classic (data = dd, target_indices = c (ncol (titanicDF)), feature_count = 10) variableImportance <-data.frame ('importance' = feats @ mi_matrix [nrow (feats @ mi_matrix),]) variableImportance $ feature <-rownames (variableImportance) row.names (variableImportance) <-NULL VAR is widely used and has both advantages and disadvantages. Value At Risk, known as VAR, is a common tool for measuring and managing risk in the financial industry.
