`kaal:entity:synthetic-data`

**Status.** derived

This node is assembled mechanically from the 2 claims that carry the concept tag `synthetic-data`. It is a roster of what the corpus says under this term. It is **not** an adjudicated definition: no single statement here has been ruled canonical, and no first-appearance call has been made. Read the claims and judge for yourself.

## Every claim under this term

2 claims across 2 works, 2025 to 2026.

**2025**

- [5095633-011](https://wulfkaal.github.io/claims/5095633-011) [mechanism/evidenced] *(failure mode)* -- As AI-generated content proliferates online it dilutes the diversity and originality of the text pool available for later training, producing performance degradation across successive model generations.
  > As AI-generated content proliferates online, it dilutes the overall diversity and originality of text available for subsequent training processes, potentially leading to a degradation in model performance over repeated generations.

**2026**

- [7598518-015](https://wulfkaal.github.io/claims/7598518-015) [condition/reported] -- 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.
  > Intelligence models increasingly learn from data that earlier Intelligence models produced, and when that loop repeats the rare cases disappear first. This paper preregisters a test of whether a reputation-weighted validator pool, filtering the training data of a recursive replacement loop, keeps those rare cases alive. The outcomes remain sealed until a replication of the original model-collapse result succeeds.
