| ## Usage | |
| Use any or all of the following tags to summon Mari: `mari, halo, 1girl, blue eyes, orange hair, hair ornament` | |
| - Hair and eye tags are optional. | |
| - It is recommended to add `cat ears` or `animal ear headwear`, otherwise her ears may not appear consistently. This is likely because Mari's veil prevents the AI from strongly associating her ears with the `mari` tag. | |
| - If Mari's ears are appearing through her veil, try adding `animal ear fluff` to the negative prompt. | |
| For her normal outfit: `single braid, animal ear headwear, nun, habit, blue neckerchief, white sailor collar, puffy long sleeves` | |
| For her sportswear alt: `low ponytail, gym uniform, gym shirt, ponytail, white headband, id card, bottle` | |
| - Add `track jacket, sportswear` for her jacket. Use `open jacket, off shoulder` instead when the jacket should be open. | |
| - Use `wet, wet clothes` for transparent/wet clothing | |
| For her swimsuit: `black one-piece swimsuit, frilled swimsuit, frills, paw print` | |
| - You will likely need to add `competition swimsuit` to the negative prompt. | |
| ## Training | |
| *Exact parameters are provided in the accompanying JSON files.* | |
| - Trained on a set of 253 images | |
| - Datset included a mixture of SFW/NSFW. | |
| - 3 repeats | |
| - 3 batch size, 7 epochs | |
| - `(253*3) / 3 * 7` = 1771 steps | |
| - Increased steps for stronger fit due to larger, more varied dataset. | |
| - 768x768 training resolution | |
| - `constant_with_warmup` scheduler | |
| - Initially tagged with WD1.4 Convnext model, then heavily edited. | |
| - Pruned redundant tags and simplified outfit tags such that Mari's outfit was always described with the same words | |
| - Ensured unique traits such as `halo` were consistent with actual visibility | |
| - Added many tags for facial expressions, camera angles, and image composition | |
| - Used network_dimension 128 (same as usual) / network alpha 128 (default) | |
| - Trained without VAE. | |

| ## Revisions | |
| - v5b (2023-02-08) | |
| - Completely re-trained to correct issue where caption files were not being loaded correctly. New version should have more flexibility but requires additional outfit prompting. | |
| - v4 (2023-01-20) | |
| - Initial release. | |
| - **Issue:** caption files were completely ignored during training. As a result, prompting "sora" grants a very strong effect, but the LoRA is highly overfit. | |
| ## Alternate Version - v4 | |
| **v4** is also available. This version was improperly configured and ignored caption files, so it was trained on the word `mari` only. It looks quite good, however the model is very overfit and it is difficult to adjust Mari's outfit. In the example image below, the prompt includes `yellow dress` but the model ignores the color and instead uses a dress that resembles Mari's usual outfit. | |
