Parameter-efficient fine-tuning (PEFT) that was initially developed for exploiting pre-trained large language models has recently emerged as an effective approach to perform transfer learning on computer vision tasks. However, the effectiveness of PEFT on medical vision foundation models is still unclear...
B.3. Latent diffusion model LDM is basically a combination of the encoders, decoders, and DDPM, where DDPM is present in the latent space. We use the implementation of DDPM from here.2 Its default parameter settings are used in our experiments except for the input size and denoising object...
D.4. Here we outperform the state of the art diffusion model ADM [15] while significantly reducing computational requirements and parameter count, cf . Tab 18. 4.3.2 Convolutional Sampling Beyond 256*256 通过将空间对齐的条件信息连接到 θ 的输入,LDM 可以用作高效的通用图像到图像转换模型。我们...
This is reminiscent of a cyclic orbit generated as a Hopf bifurcation from a stable equilibrium when some parameter achieves a critical level. A remarkable feature of Turing’s model is that, though diffusion is usually a stabilizing motion, returning a system to a uniform equilibrium state and ...
16、SVDiff: Compact Parameter Space for Diffusion Fine-Tuning 扩散模型在文本到图像生成方面取得了显著的成功,能够通过文本提示或其他模态创建高质量的图像。然而,现有的定制这些模型的方法在处理多个个性化主体和过拟合的风险方面存在局限。此外,它们的大量参数对于模型的存储来说是低效的。 本文提出一种解决现有文本...
The confidence threshold 𝜎𝑏𝑡𝑚σbtm is an important hyperparameter of the label-matching refinement method, which determines whether clustering needs to be fine-tuned and the range involved in the fine-tuning process. Thus, we investigate how the confidence threshold 𝜎𝑏𝑡𝑚σbtm ...
The dim parameter specifies the number of feature maps before the first down-sampling, and the dim_mults parameter provides multiplicands for this value and successive down-samplings: model = Unet( dim = 64, dim_mults = (1, 2, 4, 8) ) Now that our network architecture is defined, ...
We can load a pretrained diffusion model using theHugging Facediffuserslibrary. The library provides a high-level pipeline that can be used to create images directly. We’ll load theddpm-celebahq-256model,one of the first shared diffusion models for image generation. This model was trained with...

Table 2. Training parameter setting. The VQ-Diffusion model, which combines diffusion principles and the Transformer architecture, has significant computational complexity. The diffusion model generates images through multiple iterative processes, with each iteration (denoising process) requiring complex calcu...
