چکیده
and where the first inequality follows from the definition (2) of the weak-learning condition. Let λ∗ be a minimizer of the min-max expression. Unless the first entry of each-row of (Hλ∗ −B) is the largest, the right hand side of the min-max expression can be made arbitrarily large by choosing C ∈ Ceor appropriately. For example, if in some row i, the j0th element is strictly larger than the first element, by choosing

The Boosting Approach to Machine Learning An Overview
Boosting is a general method for improving the accuracy of any given learning algorithm. Focusing primarily on the AdaBoost algorithm, this chapter overviews some of the recent work on boosting including analyses of AdaBoost’s training error and generalization error; boosting’s connection to game theory and linear programming; the relationship between boosting and logistic regression; extension...
متن کاملMulti-Resolution Cascades for Multiclass Object Detection
An algorithm for learning fast multiclass object detection cascades is introduced. It produces multi-resolution (MRes) cascades, whose early stages are binary target vs. non-target detectors that eliminate false positives, late stages multiclass classifiers that finely discriminate target classes, and middle stages have intermediate numbers of classes, determined in a data-driven manner. This M...
متن کاملA Theory of Multiclass Boosting
Boosting combines weak classifiers to form highly accurate predictors. Although the case of binary classification is well understood, in the multiclass setting, the “correct” requirements on the weak classifier, or the notion of the most efficient boosting algorithms are missing. In this paper, we create a broad and general framework, within which we make precise and identify the optimal requir...

متن کاملLearning Deep Resnet Blocks Sequentially
We prove a multiclass boosting theory for the ResNet architectures which simultaneously creates a new technique for multiclass boosting and provides a new algorithm for ResNet-style architectures. Our proposed training algorithm, BoostResNet, is particularly suitable in non-differentiable architectures. Our method only requires the relatively inexpensive sequential training of T “shallow ResNet...
