3. Consistency Models定义 CMs 的核心思想是学习一个一致性函数,将 PF-ODE 轨迹上的任意点映射到该轨迹的起点 (即 PF-ODE 的解),如公式 f: (x_t, t) → x_ϵ 所示 f 以时间步长 t 上的样本 xt 为输入,期望在任意输入xt下,都可以输出对 PF-ODE 在时间 t=0 时的解。 x_t 表示时间步长 t ...
DDPM通过学习逆向扩散过程操作。它在每一步预测噪声并逐步去除,通过学习的马尔可夫链p_\theta(x_{t-1}|x_t)从纯噪声中构建数据分布。 DDIM通过使逆向过程显式和确定性来改进这一点。它知道如何从一个噪声版本x_t跳到一个较少噪声的版本x_{t-1},而无需概率性地猜测噪声,使用从已知前向过程动力学派生的...
LATENT CONSISTENCY MODELS 作者在文章中提到,尽管之前的一致性模型 (CMs) 专注于 ImageNet 64×64 和 LSUN 256×256 的图像生成任务,但它们在高分辨率的文本到图像任务上的潜力仍未被探索。为了解决这更具挑战性的任务,作者提出了“潜在一致性模型” (LCMs)。与 LDMs 类似,LCMs 在图像潜在空间中采用一致性模型,...
In this work, we propose FastVideoEdit, an efficient zero-shot video editing approach inspired by Consistency Models (CMs). By leveraging the self-consistency property of CMs, we eliminate the need for time-consuming inversion or additional condition extraction, reducing editing time. Our method ...
To ensure correct system behavior, SoC verification techniques must account for inter-component interactions through shared memory, which necessitates reasoning about memory consistency models (MCMs) This paper presents ILA-MCM, a symbolic reasoning framework for automated SoC verification, where MC...

Versatility: Integrated with LoRA technology, TCD can be directly applied to various models (including the custom Community Models, styled LoRA, ControlNet, IP-Adapter) that share the same backbone, as demonstrated in theUsage. Avoiding Mode Collapse: TCD achieves few-step generation without the ne...
