A Cost-Sensitive Ensemble Method for Class-Imbalanced Datasets
and Applied Analysis 3 costs for the positive and negative classes, SVM can be extended to the cost-sensitive setting by introducing an additional parameter that penalizes the errors asymmetrically. Consider that we have a binary classification problem, which is represented by a data set {(x 1 , y 1 ), (x 2 , y 2 ), . . . , (x l , y l )}, where x i ⊂ R represents a k-dimensional data point and ...
متن کاملA Pareto-based Ensemble with Feature and Instance Selection for Learning from Multi-Class Imbalanced Datasets
Imbalanced classification is related to those problems that have an uneven distribution among classes. In addition to the former, when instances are located into the overlapped areas, the correct modeling of the problem becomes harder. Current solutions for both issues are often focused on the binary case study, as multi-class datasets require an additional effort to be addressed. In this resea...
متن کاملMulti-objective genetic fuzzy classifiers for imbalanced and cost-sensitive datasets
We exploit an evolutionary three-objective optimization algorithm to produce a Pareto front approximation composed of fuzzy rule-based classifiers (FRBCs) with different trade-offs between accuracy (expressed in terms of sensitivity and specificity) and complexity (computed as sum of the conditions in the antecedents of the classifier rules). Then, we use the ROC convex hull method to select th...
متن کاملDynamic Cost-sensitive Ensemble Classification based on Extreme Learning Machine for Mining Imbalanced Massive Data Streams
In order to lower the classification cost and improve the performance of the classifier, this paper proposes the approach of the dynamic cost-sensitive ensemble classification based on extreme learning machine for imbalanced massive data streams (DCECIMDS). Firstly, this paper gives the method of concept drifts detection by extracting the attributive characters of imbalanced massive data stream...
متن کاملLarge-Scale Learning with Structural Kernels for Class-Imbalanced Datasets
Much of the success in machine learning can be attributed to the ability of learning methods to adequately represent, extract, and exploit inherent structure present in the data under interest. Kernel methods represent a rich family of techniques that harvest on this principle. Domain-specific kernels are able to exploit rich structural information present in the input data to deliver state of ...
