This is a low-quality bocchi-the-rock (ぼっち・ざ・ろっく!) character model.
|
10 |
+
Similar to my [yama-no-susume model](https://huggingface.co/alea31415/yama-no-susume), this model is capable of generating **multi-character scenes** beyond images of a single character.
|
11 |
+
Of course, the result is still hit-or-miss, but I think the success rate of getting the **entire Kessoku Band** right in one shot is already quite high,
|
12 |
+
and otherwise, you can always rely on inpainting.
|
13 |
+
Here are two examples:

### Characters
|
23 |
+
|
24 |
+
The model knows 12 characters from bocchi the rock.
|
25 |
+
The ressemblance with a character can be improved by a better description of their appearance.

### Dataset description
|
30 |
+
|
31 |
+
The dataset contains around 27K images with the following composition
|
32 |
+
- 7024 anime screenshots
|
33 |
+
- 1630 fan arts
|
34 |
+
- 18519 customized regularization images
|
35 |
+
|
36 |
+
The model is trained with a specific weighting scheme to balance between different concepts.
|
37 |
+
For example, the above three categories have weights respectively 0.3, 0.25, and 0.45.
|
38 |
+
Each category is itself split into many sub-categories in a hierarchical way.
|
39 |
+

### Training Details
|
43 |
+
|
44 |
+
#### Trainer
|
45 |
+
The model is trained using [EveryDream1](https://github.com/victorchall/EveryDream-trainer) as
|
46 |
+
EveryDream seems to be the only trainer out there that supports sample weighting (through the use of `multiply.txt`).
|
47 |
+
Note that for future training it makes sense to migrate to [EveryDream2](https://github.com/victorchall/EveryDream2trainer).
|
48 |
+
|
49 |
+
#### Hardware and cost
|
50 |
+
The model is trained on runpod using 3090 and cost me around 15 dollors.
|
51 |
+
|
52 |
+
#### Hyperparameter specification
|
53 |
+
|
54 |
+
- The model is trained for 48000 steps, at batch size 4, lr 1e-6, resolution 512, and conditional dropping rate of 10%.
|
55 |
+
|
56 |
+
Note that as a consequence of the weighting scheme which translates into a number of different multiply for each image,
|
57 |
+
the count of repeat and epoch has a quite different meaning here.
|
58 |
+
For example, depending on the weighting, I have around 300K images (some images are used multiple times) in an epoch,
|
59 |
+
and therefore I did not even finish an entire epoch with the 48000 steps at batch size 4.
|
60 |
+
|
61 |
+
### Failures
|
62 |
+
|
63 |
+
- For the first 24000 steps I use the trigger words `Bfan1` and `Bfan2` for the two fans of Bocchi.
|
64 |
+
However, these two words are too similar and the model fails to different characters for these. Therefore I changed Bfan2 to Bofa2 at step 24000.
|
65 |

+

+
