We … Webow patterns that mislead network anomography techniques into missing the anomalous tra c ows? In this paper, we show that the answer is \yes" for anomography techniques based on PCA [2]. We present four data poisoning schemes that increase the vari-ance of network tra c along the links of a target ow during the training phase of this algorithm.

WebJul 1, 2024 · As for the anomalous component A, following previous notation, A i,: denotes the anomalous traffic data at all time slots of i th OD flow. Unlike normal component, anomalies in network are expected to occur occasionally. Therefore, only a small fraction of time slots are supposed to be anomalous for a given flow, which means A i,: is sparse in … WebThis paper addresses network anomography, that is, the problem of inferring network-level anomalies from indirect link measurements.
