I guess you need SVD to figure out that if you have two emotional trajectory states (rise or fall) that these can only toggle (since "rise, rise" is just a bigger "rise" and "fall, fall" is just a bigger "fall"). So you pick the initial emotional state and then toggle however many states are in the story. If you have at most three states then you get 2*3 trajectories. 1. rise 2. fall 3. rise, fall 4. fall, rise 5. rise, fall, rise 6. fall, rise, fall Sorry, I don't find this particularly insightful. The insight would have been if certain sequence lengths were more important or excluded. Or other parameters about the states.
