Comparing accuracy of prediction of Alzheimer’s diagnosis by Machine Learning Algorithms Random Forest, Boosted Trees and Linear Discriminant Analysis to a stack prediction of all the three Algorithms.
In this post, what I want to show is how the Machine Learning algorithms Random Forest, Boosted Trees and Linear Discriminant Analysis will compare to a stack or an ensemble of all of them together. Load the Alzheimer’s data using the following commands library(caret) library(gbm) set.seed(3433) library(AppliedPredictiveModeling) data(AlzheimerDisease) adData = data.frame(diagnosis,predictors) inTrain = createDataPartition(adData$diagnosis, p […]
