| # Style encoder (BOM-30) |
|
|
| Authorship style embeddings (Amendment 24): the time-locked model fine-tuned with a contrastive |
| objective so that passages by the same author land close together. `297m/style.pt` and |
| `590m/style.pt` are the encoders on the 297M and 590M backbones (`style_embed.train.StyleEncoder` |
| in the GitHub repository; `load_encoder(path, cfg, "base")` or `"mid"`), with their training |
| logs. Benchmark: 297M 0.839 right author, 0.500 false matches (`benchmark_297m.json`); 590M 0.839, |
| 0.628 (`benchmark_590m.json`). |

| ## About |
|
|
| Part of an open, pre-registered study of the authorship, borrowing and dating of the |
| earliest Book of Mormon text (https://github.com/lifehug/book-of-mormon-authorship; pre-registration https://osf.io/6ugxc/). The project does not argue for or |
| against divine inspiration. Everything is published so it can be checked and redone; the corpus |
| texts we agreed to keep private are not, and the repository's `docs/replication.md` gives the |
| steps to obtain the same access. |
