This article describes the construction of the local logistic classifier, a highly scalable and parallelizable classifier combining local learning with a logistic classifier. To speed up the learning of each local logistic classifier, a novel fixed point algorithm is introduced. The practicality and performance of the classifier is demonstrated on a 10 million character training set derived fro...

A novel two-stage construction algorithm for linear-in-the-parameters classifier is proposed, aiming at noisy two-class classification problems. The purpose of the first stage is to produce a prefiltered signal that is used as the desired output for the second stage to construct a sparse linear-in-the-parameters classifier. For the first stage learning of generating the prefiltered signal, a tw...

In this paper, we develop a target detection algorithm based on a supervised learning technique that maximizes the margin between two classes, i.e., the target class and the non-target class. Specifically, our target detection algorithm consists of 1) image differencing, 2) maximum-margin classifier, and 3) diversity combining. The image differencing is to enhance and highlight the targets so t...

We present a new classification algorithm capable of learning from data corrupted by a class dependent uniform classification noise. The produced classifier is a linear classifier, and the algorithm works seamlessly when using kernels. The algorithm relies on the sampling of random hyperplanes that help the building of new training examples of which the correct classes are known; a linear class...

This paper presents an R package, arulesCBA, which uses association rules mined with the apriori algorithm from arules to build a classifier for discrete or transactional data sets. The package also provides an interface to use an association-rule classifier to predict classes for new data entries. The classification algorithm implemented in arulesCBA performs competitively when compared to exi...
