Sixteen possible transitions corresponding to profile shown in Figure 7 (a) are shown as chessboard, the darker the area of a cell the more probable a transition. Emissions corresponding to each of the four hidden HMM states are shown below the transitions matrix. MAP classified 100 ms toggle sample from the learning set corresponding to a certain profile is also shown.
