On-line boosting is one of the most successful on-line algorithms and thus applied in many computer vision applications. However, even though boosting, in general, is well known to be susceptible to class-label noise, on-line boosting is mostly applied to self-learning applications such as visual object tracking, where label-noise is an inherent problem. This paper studies the robustness of on-line boosting. Since mainly the applied loss function determines the behavior of boosting, we propose
more » ... n on-line version of GradientBoost, which allows us to plug in arbitrary lossfunctions into the on-line learner. Hence, we can easily study the importance and the behavior of different lossfunctions. We evaluate various on-line boosting algorithms in form of a competitive study on standard machine learning problems as well as on common computer vision applications such as tracking and autonomous training of object detectors. Our results show that using on-line Gradient-Boost with robust loss functions leads to superior results in all our experiments.
