classifier

the k-NN Regressor and the thought of prediction based on distance, we now take a look at the k-NN Classifier. The principle is identical, but classification allows us to introduce several useful variants, reminiscent...

Once you run a binary classifier over a population you get an estimate of the proportion of true positives in that population. That is referred to as the prevalence.An ROC curve like this one...

ENSEMBLE LEARNINGPutting the burden where weak learners need it mostEveryone makes mistakes — even the only decision trees in machine learning. As a substitute of ignoring them, AdaBoost (Adaptive Boosting) algorithm does something different:...
