Training Stable Diffusion with Dreambooth using Diffusers
Dreambooth is a powerful tool for generating high-quality images. However, it is prone to overfitting, which can result in noisy or low-quality outputs. To overcome this challenge, we need to find the right balance between the number of training steps and the learning rate.
One approach to achieve stable diffusion training with Dreambooth is to start with a low learning rate and gradually increase the number of training steps until satisfactory results are obtained. This allows the model to learn and adapt to the data without overfitting.
In our experiments, we found that running Dreambooth with a batch size of 2 and a learning rate of 1e-6 for 800-1200 steps yielded good results. However, it is important to note that these values may vary depending on the specific task and dataset.
When training on facial images, it is crucial to pre-process the data to prevent overfitting. This step may not be as critical for other subjects. If you notice noise or a decrease in image quality in the generated outputs, it is a sign of overfitting. In such cases, the aforementioned approach can help mitigate overfitting. Additionally, you can try using the DDIM scheduler or running more inference steps (around 100 in our experiments) to further improve the image quality.
Apart from the UNet model, the training of the text encoder also plays a significant role in the overall image quality. Our best results were achieved by fine-tuning the text encoder with a low learning rate and an appropriate number of training steps. However, it is important to note that fine-tuning the text encoder requires more memory, and a GPU with at least 24 GB RAM is ideal for this purpose. If you have a 16 GB GPU, you can still train the model using techniques like 8-bit Adam, fp16 training, or gradient accumulation, which are available on platforms like Google Colab or Kaggle.
Whether to use or not use Exponential Moving Average (EMA) for fine-tuning the text encoder produces similar results. Therefore, it is not necessary to use this technique specifically for training Dreambooth.
Lastly, it is worth mentioning that there is no need to use specific keywords to train Dreambooth. The initial implementation used the "sks" token because it was a rare token in the vocabulary, but it is actually a reference to a rifle. Our experiments, as well as those conducted by @nitrosocke, have shown that you can choose natural and relevant terms to describe the desired output.
In conclusion, training stable diffusion with Dreambooth using diffusers is a challenging yet rewarding task. By following the recommended approaches, such as gradually increasing the number of training steps, fine-tuning the text encoder, and using appropriate learning rates, you can achieve high-quality image generation. Remember to monitor for signs of overfitting and implement mitigation strategies accordingly.
Actionable Advice:
- 1. Start with a low learning rate and gradually increase the number of training steps to find the optimal balance for stable diffusion training with Dreambooth.
- 2. Pre-process facial images to prevent overfitting during training. Experiment with different batch sizes and learning rates to achieve the best results.
- 3. Fine-tune the text encoder with a low learning rate and an appropriate number of training steps for improved image quality. Consider using techniques like 8-bit Adam, fp16 training, or gradient accumulation to train on GPUs with limited memory.
