A Classification Method Based on Feature Selection for Imbalanced Data

open access: yesIEEE Access, 2019
Imbalanced data are very common in the real world, and it may deteriorate the performance of the conventional classification algorithms. In order to resolve the imbalanced classification problems, we propose an ensemble classification method that ...

CUSBoost: Cluster-based Under-sampling with Boosting for Imbalanced Classification

open access: yes, 2017
Class imbalance classification is a challenging research problem in data mining and machine learning, as most of the real-life datasets are often imbalanced in nature.

Partial Resampling of Imbalanced Data

open access: yes, 2022
Imbalanced data is a frequently encountered problem in machine learning. Despite a vast amount of literature on sampling techniques for imbalanced data, there is a limited number of studies that address the issue of the optimal sampling ratio. In this paper, we attempt to fill the gap in the literature by conducting a large scale study of the effects ...

Class prediction for high-dimensional class-imbalanced data

open access: yesBMC Bioinformatics, 2010
Background The goal of class prediction studies is to develop rules to accurately predict the class membership of new samples. The rules are derived using the values of the variables available for each subject: the main characteristic of high-dimensional

Understanding imbalanced data: XAI & interpretable ML framework

open access: yesMachine Learning
AbstractThere is a gap between current methods that explain deep learning models that work on imbalanced image data and the needs of the imbalanced learning community. Existing methods that explain imbalanced data are geared toward binary classification, single layer machine learning models and low dimensional data.

CUS-RF-Based Credit Card Fraud Detection with Imbalanced Data

open access: yesJournal of Risk Analysis and Crisis Response (JRACR), 2022
With the continuous expansion of the banks' credit card businesses, credit card fraud has become a serious threat to banking financial institutions. So, the automatic and real-time credit card fraud detection is the meaningful research work.

Unsupervised Learning with Imbalanced Data via Structure Consolidation Latent Variable Model

open access: yes, 2016
Unsupervised learning on imbalanced data is challenging because, when given imbalanced data, current model is often dominated by the major category and ignores the categories with small amount of data.

Extending Bagging for Imbalanced Data [PDF]

open access: yes, 2013
Various modifications of bagging for class imbalanced data are discussed. An experimental comparison of known bagging modifications shows that integrating with undersampling is more powerful than oversampling. We introduce Local-and-Over-All Balanced bagging where probability of sampling an example is tuned according to the class distribution inside ...

Dual generative adversarial networks based on regression and neighbor characteristics.

open access: yesPLoS ONE
Imbalanced data is a problem in that the number of samples in different categories or target value ranges varies greatly. Data imbalance imposes excellent challenges to machine learning and pattern recognition.
