In AdaBoost, we define the error for a base model fmx as m = yn,fmxn m

In AdaBoost, we define the error for a base model fm¹xº as m =

Í

yn,fm¹xnº ¯¹mº

n . We normally have m

.

We then reweight the training samples for the next round as

Compute the error of the same base model fm¹xº on the reweighted data, that is,

and explain how ˜ m differs from the m+1 that will be computed in the next round.
