Score-Based Generative Modeling through Stochastic Differential Equations The score-based diffusion model is a method for estimating the gradient of data distribution. It can generate images of the same high quality as GAN without the need for adversarial training. From the article: Yang Song, Jascha Sohl-Dickstein, Diederik P. Kingma, Abhishek Kumar, Stefano Ermon, and Ben Poole. […]

Linear stochastic IFS iteration method (C++)
Article directory Algorithm Description Algorithm implementation Case Analysis IFS is the abbreviation of Iterated Function System. It is a mathematical tool often used in computer graphics to generate fractal images. In IFS, a set of iterative functions is defined, and starting from a simple initial value, By repeatedly applying these functions, complex structures can be […]

Batch Gradient Descent, Mini-Batch GD, Stochastic GD
1. Gradient descent method In machine learning algorithms, for many supervised learning models, it is necessary to construct a loss function for the original model, and the next step is to optimize the loss function through an optimization algorithm in order to find the optimal parameters. In the optimization algorithm for solving machine learning parameters, […]
