QUESTION
I am trying to understand this example of the KNN algorithm in R by Datacamp: Machine Learning in R for beginners
I am having trouble understanding how they execute sampling to set up the training and test data sets.
I am able to follow the code till this line:
...ANSWER
Answered 2018-Aug-05 at 09:47My question is how are the variable ind and the iris data set related.
They're not, but they needn't be. For example, there is no intrinsic relationship between the numbers 1-5 and the iris dataset, yet
QUESTION
Just follow a ML tutorial (https://machinelearningmastery.com/machine-learning-in-r-step-by-step/). I'm trying to predict a single output on a single vector.
I'm using the IRIS dataset, and trying to predict with an LDA Algorythm. I'm trying to use my nval vector (c(4.3,3.1,1.5,0.1) to predict a single outcome, what Species is it?

control <- trainControl(method="cv", number=10)
metric <- "Accuracy"
validation_index <- createDataPartition(iris$Species, p=0.80, list=FALSE)
validation <- iris[-validation_index,]
dataset <- iris[validation_index,]
fit.lda <- train(Species~., data=dataset, method="lda", metric=metric,
