Clustering-based undersampling in class-imbalanced data - ScienceDirect Class imbalance is often a problem in various real-world data sets, where one class (i.e. the minority class) contains a small number of data points and th... Wei-Chao,Lin,Chih-Fong,... - 《Information Sciences》 被...
Instead, the goal is to group objects into clusters based only on their observable features, such that each cluster contains objects with similar properties and different clusters have distinct features. There have been numerous approaches to generating these clusters. Partitional methods such as K-...

For example, by keeping the sparsity constraint strict enough, a model based on a few parameters can be formed, exhibiting less overfitting. In the case of noise and outliers, it has been shown that under certain conditions, it is highly probable that sparse and redundant representations admit ...

Interpretability is the dominant feature of a fuzzy model in security-oriented fields. Traditionally fuzzy models based on expert knowledge have obtained well interpretation innately but imprecisely. Numerical data based fuzzy models perform well in prec
We present a clustering-based network anomaly detection model, which includes network traffic data collection, data reduction including data sampling and dimension reduction, clustering-based anomaly detection modeling and anomaly detection results evaluation. This model can effectively handle network anomaly ...
We prove the convergence of this scheme under mild sampling conditions, and we derive guarantees for the clustering obtained in terms of the cluster membership distributions. Our theoretical results are cooroborated by preliminary experiments on man-ufactured data and on real data....
