Diffusion algorithms
In machine learning, diffusion models, also known as diffusion probabilistic models, are a class of latent variable models. They are Markov chains trained using variational inference. The goal of diffusion models is to learn the latent structure of a dataset by modeling the way in which data points diffuse through the latent space. In computer vision, this means that a neural network is trained to denoise images blurred with Gaussian noise by learning to reverse the diffusion proces…

WebJun 20, 2024 · The diffusion algorithm in Equation (14) is used in each DG to find the optimal incremental cost. The secondary control objective of frequency is added in the diffusion algorithm to improve the frequency of the MG system. Unlike the conventional distributed operation strategy, the constraint of power balance is maintained by … WebCLIP-Guided Diffusion is a text-to-image AI algorithm that combines two types of neural networks to generate images. "Diffusion" works by gradually training a neural network to reverse a process of adding "noise" (random pixels) to an image. Once trained, the neural network can generate new images from nothing but random noise.
