Choosing prediction models Proactive (trigger-sensitive, incremental, historical and proactive) - A proactive approach predicts the oncoming concept given the current concept (s) by evidence from the concept history -Once a new trigger is detected that indicates the concept has changed, the predicted concept immediately takes over the classification task - In the proactive style, the history of concepts is treated like a Markov Chain -A transition matrix can be constructed from the concept history and dynamically updated upon each future occurrence of concept change.
