In real-world sensor networks, the monitored processes generating time-stamped data may change drastically over time. An online data-mining algorithm called OLIN (on-line information network) adapts itself automatically to the rate of concept drift in a non-stationary data stream by repeatedly constructing a classification model from every sliding window of training examples. In this paper, we introduce a new real-time data-mining algorithm called IOLIN (incremental on-line information network), which saves a significant amount of computational effort by updating an existing model as long as no major concept drift is detected. The proposed algorithm builds upon the oblivious decision-tree classification model called “information network” (IN) and it implements three different types of model updating operations. In the experiments with multi-year streams of traffic sensors data, no statistically significant difference between the accuracy of the incremental algorithm (IOLIN) vs. the regenerative one (OLIN) has been observed.
