Figure 7. Classification and alignment accuracies when we have removed components of the model.
The panels show distortion not present (A) and present (B). The first model is the three-segment generative model as before. The second disallows any amplitude changes at all, while the third allows any amplitude coefficient with no penalty to the score. Likewise, the fourth disallows stretching and the fifth allows any stretching without penalty. Highlights indicate a significant difference from the unaltered three-segment model (p≤0.05 with McNemar's χ 2 test).
