Abstract:
A method and system for identification of a deviation from a periodic behavior pattern in a sequence of multimedia content segments are provided. The system comprises receiving the sequence of multimedia content segments; generating at least one signature for each multimedia content segment of the sequence of multimedia content segments; comparing at least two signatures generated for at least two consecutive multimedia content segments to detect a periodic behavior pattern; upon detecting the periodic behavior pattern, comparing at least one signature generated for at least a subsequently received multimedia content segment to at least one signature representing the detected multimedia content segment to identify a deviation from the periodic behavior pattern; and upon identifying the deviation from the periodic behavior pattern, generating a notification with respect to the at least one deviation.

Abstract:
A method and system for signature-based unsupervised clustering of data elements. The method comprises receiving a plurality of clusters; generating a triangular matrix respective of the clusters; generating a signature for each of the clusters; generating a match score between each of two different clusters; storing the match score in a cell of the triangular matrix corresponding to the two clusters; determining whether any of the match scores is above a predefined threshold value; clustering every two clusters that are determined to have a score above a predetermined threshold; and repeating the generation of a triangular matrix respective of the clusters until a single cluster is reached. The system comprises an interface; a processor; a memory for storing at least one cluster; and a memory coupled to the processor, the memory containing instructions that, when executed by the processor, configure the system to perform the steps of the method.
