另外注意到,应用Classifier-Free Guidance的diffusion极大地提高了生成样本质量,故LDM-KL-8-G与以往最先进的AR和diffusion模型在文本到图像合成方面的性能不相上下,同时大大减少了参数量。 另外还在OpenImages上训练了基于语义布局(semantic layouts)的图像合成模型,并在COCO上进行了微调,结果如上图。 另外评估了在Image...
Stable Diffusion 的采样过程可以被当作一个定义在二维 Lattice 上标量场的准平衡态动力学演化。 标量场 很显然,Stable Diffusion 的采样的目标是一个离散化的二维格点,或者说位图。只要有常识且不是盲人,应该没有任何理解困难。 其实这一点其实是最晦涩的,因为几乎所有的理论形式化都不涉及空间概念。甚至在我最初的...
Our 1.45B latent diffusion LAION model was integrated into Huggingface Spaces 🤗 using Gradio. Try out the Web Demo: More pre-trained LDMs are available: A 1.45B model trained on the LAION-400M database. A class-conditional model on ImageNet, achieving a FID of 3.6 when using classifi...
We introduce SQ-DiffuPep, a novel latent diffusion-based model that significantly outperforms existing methods in discovering highly active antimicrobial peptide candidate sequences.Our innovative soft quantization and shifted-window attention mechanisms effectively address the codebook collapse problem in VQ-...

Exploiting Latent Information to Predict Diffusions of Novel Topics on Social Networks - tsungtingkuo/diffusion
为解决预测序列与历史序列的速度和方向连贯性,将这部分信息和动作行为信息解耦出来,通过diffusion model编码到潜空间中。由于解耦之后,通过潜变量生成的动作会更加真实。 Contributions BeLFusion model diversity motion prediction cross-dataset evaluation new metrics ...
When there exists additional information associated with training data, the diffusion models can be trained in a conditional manner. We leverage the Bird's Eye View (BEV) segmentation map in Carla and train the model to generate scenes conditioned on a given BEV map. In BEV maps, each color...
To enable DM training on limited computational resources while retaining their quality and flexibility, we apply them in the latent space of powerful pretrained autoencoders. In contrast to previous work, training diffusion models on such a representation allows for the first time to reach a near-...
