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.

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.

Distribution-sensitive learning for imbalanced datasets [PDF]

open access: yes2013 10th IEEE International Conference and Workshops on Automatic Face and Gesture Recognition (FG), 2013
Many real-world face and gesture datasets are by nature imbalanced across classes. Conventional statistical learning models (e.g., SVM, HMM, CRY), however, are sensitive to imbalanced datasets.

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.

Fault Diagnosis of Induction Motors with Imbalanced Data Using Deep Convolutional Generative Adversarial Network

open access: yesApplied Sciences, 2022
A homemade defective model of an induction motor was created by the laboratory team to acquire the vibration acceleration signals of five operating states of an induction motor under different loads. Two major learning models, namely a deep convolutional

Class-Imbalanced Voice Pathology Detection and Classification Using Fuzzy Cluster Oversampling Method

open access: yesApplied Sciences, 2021
The Massachusetts Eye and Ear Infirmary (MEEI) database is an international-standard training database for voice pathology detection (VPD) systems. However, there is a class-imbalanced distribution in normal and pathological voice samples and different ...

Conversion of adverse data corpus to shrewd output using sampling metrics

open access: yesVisual Computing for Industry, Biomedicine, and Art, 2020
An imbalanced dataset is commonly found in at least one class, which are typically exceeded by the other ones. A machine learning algorithm (classifier) trained with an imbalanced dataset predicts the majority class (frequently occurring) more than the ...

Active Learning for Imbalanced Datasets

open access: yes2020 IEEE Winter Conference on Applications of Computer Vision (WACV), 2020
Active learning increases the effectiveness of labeling when only subsets of unlabeled datasets can be processed manually. To our knowledge, existing algorithms are designed under the assumption that datasets are balanced. However, many real-life datasets are actually imbalanced and we propose two adaptations of active learning to tackle imbalance ...
