Abnormal object in the data stream automatic the online detection and class method and the device in order to classify

摘要

The invention is concerned with a method for automatic online detection and classification of anomalous objects in a data stream, especially comprising datasets and/or signals, wherein a) the detection of at least one incoming data stream containing normal and anomalous objects, b) automatic construction of a geometric representation of normality the incoming objects of the data stream at a time tSUB1 /SUBsubject to at least one predefined optimality condition, especially the construction of a hypersurface enclosing a finite number of normal objects, c) online adaptation of the geometric representation of normality in respect to received at least one received object at a time tSUB2/SUB, which is greater than tSUB1/SUB, the adaptation being subject to at least one predefined optimality condition, d) online determination of a normality classification for received objects at tSUB2 /SUBin respect to the geometric representation of normality, e) automatic classification of normal objects and anomalous objects based on the generated normality classification and generating a data set describing the anomalous data for further processing, especially a visual representation.
