The AdaBoost Flow

We introduce a dynamical system that we call the AdaBoost flow. The flow is defined by a system of ODEs with control. We show that three algorithms of the AdaBoost family, (i) the AdaBoost algorithm of Schapire and Freund, (ii) the arc‐gv algorithm of Breiman, and (iii) the confidence rated prediction of Schapire and Singer, can be embedded in the AdaBoost flow.
