第二种方式叫做 Quantile Self-Guidance,其中计算 pθ(yobs|xt) 的方式为: pθ(yobs|xt)=1Z⋅exp(−1bmax{k⋅(yobs−fθ(xt,t)),(k−1)⋅(yobs−fθ(xt,t))})。 该过程的算法流程如下: Diffusion Guidance 算法流程 通过该算法,我们可以从高斯噪声 \mathbf{x}^T 开始,一步一步降噪...
此外还提出了一种方法迭代地改善基础预测器的性能,通过将TSDiff学习到的隐式概率密度视为基于能量的先验来减小计算开销。 Background:Diffusion Guidance利用无条件训练的图像扩散模型来进行有类别条件的图像生成。核心思想是使用贝叶斯规则对类别条件分数函数(score function)进行分解: 并且用辅助分类器去估计等式右边的第...

We propose TSDiff, an unconditionally-trained diffusion model for time series. Our proposed self-guidance mechanism enables conditioning TSDiff for downstream tasks during inference, without requiring auxiliary networks or altering the training procedure. We demonstrate the effectiveness of our method on ...
Our framework is built upon diffusion models, leveraging the principle of guided sampling that incorporates an arbitrary energy-based guidance during inference time. The key defining feature of our sampler lies in its self-contained nature, i.e ., implementable solely with a pretrained model. This...
Guidance serves as a key concept in diffusion models, yet its effectiveness is often limited by the need for extra data annotation or classifier pretraining. That is why guidance was harnessed from self-supervised learning backbones, like DINO. However, recent studies have revealed that the featur...

Erik Ericksen (1968), working in the ego-analytic tradition, argued that the development of self-identity was essential to psychological adjustment and well-being and proposed that those who failed to achieve a sense of personal identity remained in a state of identity diffusion, fated to stumble...
