Method and apparatus for clustering data stream
Provided is a method for clustering a data stream. The method comprises: acquiring a plurality of resulting models of a plurality of preceding data partitions prior to a current data partition in a data stream, wherein data partitions in the data stream have a temporal relationship, and wherein each of the plurality of resulting models is generated according to a clustering result of a corresponding preceding data partition, and each of the plurality of resulting models comprises one or more representative parameters in different categories; determining a starting model of the current data partition according to the plurality of resulting models, wherein the starting model comprises one or more representative parameters in different categories determined based on representative parameters of the same category in the plurality of resulting models; and clustering data records in the current data partition by using the starting model.
