Embodiment 1
[0057] The present invention provides an online network traffic anomaly detection method based on a tensor model, comprising:
[0058] Step 1, according to the three-dimensional tensor model, the collected network traffic raw data is modeled to form the original tensor data;
[0059] The original tensor data model in step 1 includes three dimensional vectors formed by source nodes, target nodes and time.
[0060] see figure 2 , the present invention becomes a three-dimensional tensor model (such as figure 2 ), where Origin represents the source node, Destination represents the target node, and Time represents the time. Different from vectors and matrices, the tensor model is an extension of the vector model and matrix model to multidimensionality, and tensors can represent the multidimensional nature of multimodal data. The tensor model is no longer limited to the relatively simple two-dimensional linear relationship in the data, but considers multiple dimensions together...
