Claim LD09-SL-C31 (v1.0)

In laboratory experiments, replacing real training data with each generation’s synthetic data tends towards model collapse, but accumulating synthetic data alongside the original real data avoids it; for a sequence of linear models, the authors prove that test error then has a finite upper bound however many generations pass.
