NMF-NAD: detecting network-wide traffic anomaly based on NMF
Jianjun Huang · Journal of Communications · 2012
A non-negative matrix factorization(NMF) based network wide traffic anomalies detection(NMF-NAD) method was proposed.NMF-NAD firstly reconstructed the traffic matrix in the non-negative sub-space,and then detected the anomalies through Shewhart control chart based on the reconstruction error.Experimental results on both simulation and Abilene data show that NMF-NAD can achieve high detection accuracy with low complexity.
