In 1999, the ?rst workshop on a number of classi?er structures used to be geared up with the most objective of constructing a typical overseas discussion board to advertise the diss- ination of the implications accomplished within the various groups and the adoption of a typical terminology, hence giving the di?erent views and cultural ba- grounds a few concrete further price. After ?ve conferences of this workshop, there's powerful facts that signi?cant steps were made in the direction of this target. - searchers from those assorted groups effectively participated within the wo- retailers, and global specialists offered surveys of the cutting-edge from the views in their groups to assist cross-fertilization.

Springer-Verlag, Berlin, 2003. AveBoost2: Boosting for Noisy Data Nikunj C. gov Abstract. AdaBoost [4] is a well-known ensemble learning algorithm that constructs its base models in sequence. AdaBoost constructs a distribution over the training examples to create each base model. This distribution, represented as a vector, is constructed with the goal of making the next base model’s mistakes uncorrelated with those of the previous base model [5]. We previously [7] developed an algorithm, AveBoost, that first constructed a distribution the same way as AdaBoost but then averaged it with the previous models’ distributions to create the next base model’s distribution.

The quality of the generated ensemble highly depends on the accuracy and diversity of its individual components [9]. Many methods have been proposed to construct a set of classifiers from a single evidence. These techniques have been applied in many different learning algorithms. Dietterich [3] distinguishes different kinds of ensemble construction methods, being probably the methods based on the manipulation of the training * This work has been partially supported by CICYT under grant TIC2001-2705-C0301 and MCyT Acción Integrada HU 2003-0003.

Theorem 1. In AveBoost2, suppose the weak learning algorithm generates hypotheses with errors where each Then the ensemble’s error is bounded as follows: This bound is non-trivial but greater than that of AdaBoost [4]: To derive our generalization error bound, we use the algorithmic stability framework of [6]. Intuitively, algorithmic stability is similar to Breiman’s notion of stability [2] – the more stable a learning algorithm is, the less of an effect changes to the training set have on the model returned.
