An Imbalanced Generative Adversarial Network-Based Approach for Network Intrusion Detection in an Imbalanced Dataset [PDF]

open access: yesSensors, 2023
In modern networks, a Network Intrusion Detection System (NIDS) is a critical security device for detecting unauthorized activity. The categorization effectiveness for minority classes is limited by the imbalanced class issues connected with the dataset.

Imbalanced Ensemble Classifier for Learning from Imbalanced Business School Dataset [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2019
Private business schools in India face a regular problem of picking quality students for their MBA programs to achieve the desired placement percentage. Generally, such datasets are biased towards one class, i.e., imbalanced in nature.

A Cost-Sensitive Ensemble Method for Class-Imbalanced Datasets [PDF]

open access: yesAbstract and Applied Analysis, 2013
In imbalanced learning methods, resampling methods modify an imbalanced dataset to form a balanced dataset. Balanced data sets perform better than imbalanced datasets for many base classifiers.

LoRAS: an oversampling approach for imbalanced datasets [PDF]

open access: yesMachine Learning, 2020
AbstractThe Synthetic Minority Oversampling TEchnique (SMOTE) is widely-used for the analysis of imbalanced datasets. It is known that SMOTE frequently over-generalizes the minority class, leading to misclassifications for the majority class, and effecting the overall balance of the model.
