What is the difference between creating something “truly new” and creating a “derivative work”?
Are you saying that anything that fulfills the same statistical interrelationships as the training set, is therefore a derivative of the training set?
Like if I asked the thing “What happens when I place a basketball on a table then lift one side of the table?” its answer is some derivative of other scenarios involving tilting tables with basketballs on them?
Or is it using knowledge of how “round” works, that “round” things “roll”, that “rolling” tends to go “downward”, that things reaching the edge of a platform then “fall”, etc?
These are statistically inferred relationships between words, but at a certain point recombining elements into new compositions is creation and not derivative work.
It’s like saying that Chopin made derivative work based on Beethoven because he heard Beethoven’s music and learned about beautiful note patterns from it.
