Class Rectification Hard Mining for Imbalanced Deep Learning

open access: yes, 2017
Recognising detailed facial or clothing attributes in images of people is a challenging task for computer vision, especially when the training data are both in very large scale and extremely imbalanced among different attribute classes.

Lightweight Micro-Expression Recognition on Composite Database

open access: yesApplied Sciences, 2023
The potential of leveraging micro-expression in various areas such as security, health care and education has intensified interests in this area. Unlike facial expression, micro-expression is subtle and occurs rapidly, making it imperceptible.

A Hybrid Sampling SVM Approach to Imbalanced Data Classification

open access: yesAbstract and Applied Analysis, 2014
Imbalanced datasets are frequently found in many real applications. Resampling is one of the effective solutions due to generating a relatively balanced class distribution.

Superensemble classifier for improving predictions in imbalanced datasets [PDF]

open access: yesCommunications in Statistics: Case Studies, Data Analysis and Applications, 2020
Learning from an imbalanced dataset is a tricky proposition. Because these datasets are biased towards one class, most existing classifiers tend not to perform well on minority class examples. Conventional classifiers usually aim to optimize the overall accuracy without considering the relative distribution of each class.

Imbalanced SVM-Based Anomaly Detection Algorithm for Imbalanced Training Datasets [PDF]

open access: yesETRI Journal, 2017
Abnormal samples are usually difficult to obtain in production systems, resulting in imbalanced training sample sets. Namely, the number of positive samples is far less than the number of negative samples. Traditional Support Vector Machine (SVM)‐based anomaly detection algorithms perform poorly for highly imbalanced datasets: the learned ...

Oversampling for Imbalanced Learning Based on K-Means and SMOTE

open access: yes, 2017
Learning from class-imbalanced data continues to be a common and challenging problem in supervised learning as standard classification algorithms are designed to handle balanced class distributions. While different strategies exist to tackle this problem,
