If you are tuning a Naive Bayes model using
caret, can someone explain how increasing or decreasing the Laplace smoother and bandwidth impact the results?
I understand that the Laplace smoother is to account for the zero-frequency issue, but I have been unable to find a suitable definition for bandwidth.
For example, if I have this grid
grid <- expand.grid( usekernel = c(TRUE, FALSE), fL = seq(0,5,0.5), # Bandwidth adjust = seq(0,5,0.5) # Laplace )
