- Upload images of the style you are planning on training on.
- For a concept prompt, use a unique, made up word to avoid collisions.
- Guidelines for getting good results:
- Dreambooth for an `object` or `style`:
- 5-10 images of the object from different angles
- 500-800 iterations should be good enough.
- Prior preservation is recommended.
- `class_prompt`:
- `a photo of object`
- `style`
- `concept_prompt`:
- `<concept prompt> object`
- `<concept prompt> style`
- `a photo of <concept prompt> object`
- `a photo of <concept prompt> style`
- Dreambooth for a `Person/Face`:
- 15-50 images of the person from different angles, lighting, and expressions.
Have considerable photos with close up faces.
- 800-1200 iterations should be good enough.
- good defaults for hyperparams
- Model - `runwayml/stable-diffusion-v1-5` or `stabilityai/stable-diffusion-2-1-base`
- Use/check Prior preservation.
- Number of class images to use - 200
- Prior Loss Weight - 1
- LoRA Rank for unet - 16
- LoRA Alpha for unet - 20
- lora dropout - 0
- LoRA Bias for unet - `all`
- LoRA Rank for CLIP - 16
- LoRA Alpha for CLIP - 17
- LoRA Bias for CLIP - `all`
- lora dropout for CLIP - 0
- Uncheck `FP16` and `8bit-Adam` (don't use them for faces)
- `class_prompt`: Use the gender related word of the person
- `man`
- `woman`
- `boy`
- `girl`
- `concept_prompt`: just the unique, made up word, e.g., `srm`
- Choose `all` for `lora_bias` and `text_encode_lora_bias`
- Dreambooth for a `Scene`:
- 15-50 images of the scene from different angles, lighting, and expressions.
- 800-1200 iterations should be good enough.
- Prior preservation is recommended.
- `class_prompt`:
- `scene`
- `landscape`
- `city`
- `beach`
- `mountain`
- `concept_prompt`:
- `<concept prompt> scene`
- `<concept prompt> landscape`
- Experiment with various values for lora dropouts, enabling/disabling fp16 and 8bit-Adam
