Adaptive Sampling Framework for Imbalanced DDoS Traffic Classification

open access: yesSensors
Imbalanced data is a major challenge in network security applications, particularly in DDoS (Distributed Denial of Service) traffic classification, where detecting minority classes is critical for timely and cost-effective defense.

Impact of imbalanced features on large datasets

open access: yesFrontiers in Big Data
The exponential growth of image and video data motivates the need for practical real-time content-based searching algorithms. Features play a vital role in identifying objects within images. However, feature-based classification faces a challenge due to uneven class instance distribution. Ideally, each class should have an equal number of instances and

An Improved Method of Detecting Macro Malware on an Imbalanced Dataset

open access: yesIEEE Access, 2020
In spear-phishing attacks, macro malware written in VBA (Visual Basic for Applications) is often used to compromise the target computers. Macro malware is often obfuscated in several ways to evade detection.

A Hybrid Approach Handling Imbalanced Datasets [PDF]

open access: yes, 2009
Several binary classification problems exhibit imbalance in class distribution, influencing system learning. Indeed, traditional machine learning algorithms are biased towards the majority class, thus producing poor predictive accuracy over the minority one. To overcome this limitation, many approaches have been proposed up to now to build artificially

Anomaly Detection Model for Imbalanced Datasets

open access: yes, 2020
This paper proposes a method to detect bank frauds using a mixed approach combining a stochastic intensity model with the probability of fraud observed on transactions. It is a dynamic unsupervised approach which is able to predict financial frauds. The fraud prediction probability on the financial transaction is derived as a function of the dynamic ...

SMOTEHashBoost: Ensemble Algorithm for Imbalanced Dataset Pattern Classification

open access: yesIEEE Access
Class imbalance occurs frequently in machine learning, particularly in binary classification tasks where the majority class has a significantly larger number of samples than the minority class.
