Figure 2. HMM transition matrices.

Figure 2

The SVM processes accelerometer features (Table 1) and outputs a probabilistic estimate of the state of the person. The transition matrix for the HMM gives the Prob(current hidden state | previous hidden state). A) The transition matrix for the activity-known and location-known models. B) The transition matrix for the joint activity-location classifier. The joint matrix is in a block diagonal form analogous to previous models with only slight variations in the parameters.
