wd=sqrt((1-at)/at), wp=gaussian(mean=m, var=s) 在论文中,m建议设为2/T,T为stable-diffusion的采样步数,s没有建议。论文设定m=500, s=125 Wd会使W偏斜,以减少对高方差阶段的权重,在高方差阶段,t很小。 分析: 亮点: 验证了去噪信号在不同时间步长t上提供从结构到细节的不同粒度的信息 指出了原...
Diffusion-informed spatial smoothing of fMRI data in white matter using spectral graph filters - ScienceDirect Brain activation mapping using functional magnetic resonance imaging (fMRI) has been extensively studied in brain gray matter (GM), whereas in large disreg... DAA B,ML C,AEAB G,... ...

diffusion priors and the training procedures of diffusion models that substantially impairs the quality of 3D generation. To address this issue, we propose a novel, unified framework that iteratively optimizes both the 3D model and the diffusion prior. Leveraging the different learnable parameters of ...

The evolutionary operators involve selection, crossover, and mutation, performing double scrambling and diffusion at the bit and pixel levels. This encryption scheme is designed to encrypt images of any size. For any M × N image, if M × N is even, no processing is required; if ...

People are already saying Stable Diffusion 3 trounces Midjourney and DALL-E AI's here and we’re already terribly bored Google Gemini's diversity debacle is the weirdest AI incident yet Latest in News Anycubic has another mega sale on 3D printers – and these are the 7 deals I would...
Two-dimensional (2D) and quasi-2D modifications of three-dimensional (3D) perovskite active layers have contributed to advances in the performance of perovskite solar cells (PSCs). However, the ionic diffusion between the surface 2D and bulk 3D perovskit
Membrane contact sites between virtually any known organelle have been documented and, in the last decades, their study received momentum due to their importance for fundamental activities of the cell and for the subtle comprehension of many human diseas
