Tackling class imbalance with ranking

open access: yes2016 International Joint Conference on Neural Networks (IJCNN), 2016
In classification, when there is a disproportion in the number of observations in each class, the data is said to be class imbalance. Class imbalance is pervasive in real world applications of data classification and has been the focus of much research.

Cost-Sensitive Pattern-Based classification for Class Imbalance problems

open access: yesIEEE Access, 2019
In several problems, contrast pattern-based classifiers produce high accuracy and provide an explanation of the result in terms of the patterns used for classification. However, class imbalance problems are a great challenge for these classifiers because

Class imbalance techniques for high energy physics

open access: yesSciPost Physics, 2019
A common problem in a high energy physics experiment is extracting a signal from a much larger background. Posed as a classification task, there is said to be an imbalance in the number of samples belonging to the signal class versus the number of ...
