kaal:claim:7598518-015

Claim. Feng et al. (2025) show that verifier-selected synthetic data can prevent collapse, and the paper concedes the core of that result: verifier selection is an established remedy, and the oracle ceiling and the Gaussian setting are established.

Type. condition · Support. reported

Holds when

• The result is prior work, not a finding of this study.
• What this paper isolates is how to weight several assessors behind a validity filter, not whether verifier selection works.

Source quote

The closest prior work is Feng et al. (2025), who show that verifier-selected synthetic data can prevent collapse, with Gaussian-mixture theory and experiments comparing oracle and weak verifiers with self-selection and random selection. The paper concedes the core of that result: verifier selection is an established remedy, and the oracle ceiling and the Gaussian setting are established.
