A Hybrid Classifier Based on Svm Method for Cancer Classification

In this paper, we proposed a new method of applying Support Vector Machines (SVMs) for cancer classification. We proposed a hybrid classifier that considers the degree of a membership function of each class with the help of Fuzzy Naive Bayes (FNB) and then organizes one-versus-rest (OVR) SVMs as the architecture classifying into the corresponding class. In this method, we used a novel system of...

Mining Imbalanced Data with Learning Classifier Systems

This chapter investigates the capabilities of XCS for mining imbalanced datasets. Initial experiments show that, for moderate and high class imbalances, XCS tends to evolve a large proportion of overgeneral classifiers. Theoretical analyses are developed, deriving an imbalance bound up to which XCS should be able to differentiate between accurate and overgeneral classifiers. Some relevant param...

Classifier Learning for Imbalanced Data with Varying Misclassification Costs A Comparison of kNN, SVM and Decision Tree Learning

This thesis theoretically discusses the abilities of three commonly used classifier learning methods and optimization techniques to copewith characteristics of real-world classification problems, more specifically varying misclassification costs, imbalanced data sets and varying degrees of hardness of class boundaries. From these discussions a universally applicable optimization framework is de...

A Multiple Resampling Method for Learning from Imbalanced Data Sets

Re-Sampling methods are commonly used for dealing with the class-imbalance problem. Their advantage over other methods is that they are external and thus, easily transportable. Although such approaches can be very simple to implement, tuning them most effectively is not an easy task. In particular, it is unclear whether oversampling is more effective than undersampling and which oversampling or...

A Robust Decision Tree Algorithm for Imbalanced Data Sets

We propose a new decision tree algorithm, Class Confidence Proportion Decision Tree (CCPDT), which is robust and insensitive to class distribution and generates rules which are statistically significant. In order to make decision trees robust, we begin by expressing Information Gain, the metric used in C4.5, in terms of confidence of a rule. This allows us to immediately explain why Information...
