The passage around this formula
…own prior outputs across many generations [ 4 ] . Model collapse, as demonstrated in the Shumailov paper, is specifically about the recursive case: generation n+1 trained substantially on the sampled output of generation n , repeated across many generations, with the real data anchor diluted or absent [ 1 ] . Curated, teacher-generated synthetic data used once as a supplement to real data is a different mechanism from an uncurated corpus that increasingly consists of unlabeled prior-model output scraped back off…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
