single particle diffusion/ A0550 Lattice theory and statisticsIsing problems A0560 Transport processes: theoryFollowing our previous works on lattice diffusion, and on the use of the local mean field method to describe diffusion in interacting lattice gases, we show that the latter can be also ...
What is the definition of diffusion? The movement of molecules from an area of their low concentration to their high concentration The movement of molecules across the cell membrane The movement of molecules from an area of their high concentration to their low concentration The movement of molecule...
来自专栏 · Diffusion Models 5 人赞同了该文章 引言 本文前作 VDM 已经推导出了扩散模型可以将优化 ELBO 作为目标函数。然而现在 FID (也就是感知质量)最好的模型还是用的其他目标函数(如 DDPM 的噪声预测和 Score-base Model 的得分匹配),本文证明了这些其他目标函数实际上也与 ELBO 相关。具体来说,本文证明...
The aim of the GUI is to keep things as simple as possible and yet provide as many features as is necessary to get your work done should you do a lot of image generation using Stable Diffusion. The original aim was to keep the Python package requirements as low (and simple) as possible...

That is, in the diffusion model the same rules govern evidence accumulation throughout each decision. In the UGM, there is a growing “urgency signal”, which changes the way accumulated evidence is used as the decision unfolds. There are still other differences between the models that can be...
It is sometimes referred to as the “basal lamina”. The basement membrane is clinically important in cancer, as the degree to which malignant cells penetrate it is highly relevant to prognosis. The side of the cell furthest from the basement membrane is known as the apical border. Stratified...
Brownian diffusion is known as an adverse mechanism limiting the degree of aerodynamic focus- ing of ultra ne particles (Liu et al. 1995a, b; Fernandez de la Mora and Rosell-Llompart 1989; Fernandez-Feria et al. 1991). Here Brownian diffusion can be considered in 2 regions: in- side ...
Chaos, or exponential sensitivity to small perturbations, appears everywhere in nature. Moreover, chaos is predicted to play diverse functional roles in living systems. A method for detecting chaos from empirical measurements should therefore be a key co
Mathematical modeling of avascular tumor growth is important to understand the advanced stages of cancer. Kiran et al. have developed a spatial-temporal mathematical model classified as different zone model for avascular tumor growth based on the diffusion of nutrients, their consumption, and it ...
