CHAPTER 4
 SIMULATIONS WITH SYNTHETIC DATA SET

 This chapter presents the simulation results of the monitoring approaches with the

several types of experts, using the synthetic data set generated in the previous chapter

 4.1 Linear Experts

4.1.1 Approach I: Offline Training

 Figure 4-1 shows the result of approach I simulation for a linear filter of order 10:

each expert is a Wiener filter modeling one regime, and online change detection is

performed.


Figure 4-1Results: (a) Flow: desired in blue, predicted in red; (b) MSE criterion, full line
 is for expert 1, dotted line is for expert 2; (c) Winner; (d) Pressure.

 It is obvious on the flow graph (cropped: the actual values of the predicted flow

peak out of the window!) that the data is not modeled well, as can be seen on also by
