What Is tuneLength in Knn
# the tuneLength Parameter Tells the Algorithm to Try Different Default Values for the Main Parameter Set. Seed(123) My_Knn_Model
# The tuneLength parameter tells the algorithm to try different default values for the main parameter set.seed(123) my_knn_model <- train(Species ~ ., method = “knn”, data = trainSet, tuneLength = 4) # In this case we used 4 default values my_knn_model.
What is tune length?
From the {caret} documentation: tuneLength. an integer denoting the amount of granularity in the tuning parameter grid. By default, this argument is the number of levels for each tuning parameters that should be generated by train.
What is the caret package in R?
