Abstract
Motivated by results in information­theory, we de­
scribe a modification of the popular boosting algo­
rithm AdaBoost and assess its performance both
theoretically and empirically. We provide theo­
retical and empirical evidence that the proposed
boosting scheme will have lower training and test­
ing error than the original (non­ confidence­rated)
version of AdaBoost. Our modified boosting al­
gorithm and its analysis also suggests an explana­
tion for why boosting with confidence­rated pre­
dictions often markedly outperforms boosting with­
