%X Recently, data stream has widely appeared in many applications. Mining the evolving tendency and forecasting the data values in the future time windows of streams can provide important support for the future decision in many time-sensitive applications. For example, by using predictive queries in sensor networks for all kinds of monitoring, observers can forecast future values to detect abnormal events. By mapping the stream data into the stream state space, a continuously changing tendency of an online dat...
