Web click streams and mining symbolic sequences
Web click streams data is large and continuously emerging, with hidden trends buried and to be discovered for various usages, such as recommendations. TECNO-STREAMS (Tracking Evolving Clusters in NOisy Streams) is a one-pass algorithm.
The TECNO-STREAMS algorithm
The whole algorithm is modeled on the following equations: the robust weight or activation function (1), influence zone (2), pure simulation (3), optimal scale update (4), incremental update of pure simulation and optimal update (5) and (6), the simulation and scale values (7), and finally, the D-W-B-cell update equations (8).
