Abstract
The disclosure provides a method () and apparatus for anomaly detection in a network. The method () comprises: obtaining (S) a stream of time-series data related to the network; and dividing (S) the stream into a number of sub-streams each corresponding to a category of data. The method further comprises, for each of the sub-streams: reconstructing (S) a plurality of phase spaces; predicting (S), in each of the plurality of phase spaces, whether a data item in the sub-stream is an anomaly candidate based on a prediction model associated with the phase space; and detecting (S) the data item as an anomaly when it is predicted as an anomaly candidate in all of the plurality of phase spaces.
