This is also the last chapter revolving around classification. After almost 6 months spending my week-ends on classifiers, I am rather glad to change gears a bit! The idea behind the algorithm Algorithm outline AdaBoost is short for “Adaptative Boosting”. Boosting is based on a very common-sense idea: instead of trying to find one perfect classifier t[...]
