Figure 9. Task classification matrix.

Figure 9

Rows represent the tasks requested by the interface and columns represent the tasks classified by the system. Only tasks SoftR, SoftL and Relax are requested while all five tasks (HardR, SoftR, Relax, SoftL and HardL) can be detected. The matrix is initialized with zeros at the beginning of each run and these values are updated with every classification. The thresholds are modified trying to get a diagonal matrix.
