Principles of SD Learning and Painting<\/p>\n<p>1. Learning Principles<\/p>\n<p>Stable Diffusion learns by continuously adding noise to an image. This process can be thought of as the AI gradually \"memorizing\" the features of the image. By gradually adding noise, the AI learns how to recover the original image from the noise.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-28525\" title=\"b33eed9bj00srit6t00a2d000u00076m\" src=\"https:\/\/www.1ai.net\/wp-content\/uploads\/2025\/02\/b33eed9bj00srit6t00a2d000u00076m.jpg\" alt=\"b33eed9bj00srit6t00a2d000u00076m\" width=\"1080\" height=\"258\" \/><\/p>\n<p>2\u3001Painting Principle<\/p>\n<p>In contrast to the learning process, painting is a denoising process. the AI starts with an image composed entirely of noise, gradually removes the noise, and eventually produces a clear image. This process is similar to the reverse learning process, where the AI uses its learned knowledge to gradually reveal the image hidden under the noise.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-28526\" title=\"29400bf4j00srit6t00a2d000u00079m\" src=\"https:\/\/www.1ai.net\/wp-content\/uploads\/2025\/02\/29400bf4j00srit6t00a2d000u00079m.jpg\" alt=\"29400bf4j00srit6t00a2d000u00079m\" width=\"1080\" height=\"261\" \/><\/p>\n<p>II. Iteration steps<\/p>\n<p>The number of iteration steps is the number of iterations that need to be performed in the process from the noise map to the finished map.<\/p>\n<p>The higher the number of iteration steps, the finer the denoising process and the longer the time required.<\/p>\n<p>We found experimentally that the image quality gradually improves as the number of iteration steps increases, but after a certain number of steps, the improvement in picture quality is no longer obvious.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-28524\" title=\"6f09730dp00srit6t002td000u0001am\" src=\"https:\/\/www.1ai.net\/wp-content\/uploads\/2025\/02\/6f09730dp00srit6t002td000u0001am.png\" alt=\"6f09730dp00srit6t002td000u0001am\" width=\"1080\" height=\"46\" \/><\/p>\n<p>Recommended number of iteration steps:<strong>30-40 steps<\/strong>.<\/p>\n<p>III. Sampling methods<\/p>\n<p>The sampling method determines the computational approach that SD follows at each step of the denoising process.<\/p>\n<p>We compared multiple sampling methods and found that<strong>euler a<\/strong>,<strong>euler<\/strong>and<strong>DPM++ 2M Karras<\/strong>Three samplers performed the best.<\/p>\n<p>For the uninitiated, choosing one of these three samplers will meet almost all project needs.<\/p>\n<p>Impact of sampling methods<\/p>\n<ul>\n<li><strong>Steps and time<\/strong>: Sampling methods affect the number of steps and time required for an iteration. Some sampling methods may require more steps to achieve the same result.<\/li>\n<li><strong>convergence (math.)<\/strong>: Different sampling methods have different stability during iterations. Some methods may stabilize after fewer iterations, while others require more iterations.<\/li>\n<li><strong>final result<\/strong>: Different sampling methods can have a significant effect on the quality of the final image. Some methods may produce sharper and more realistic images.<\/li>\n<li><strong>Style and Color<\/strong>: In some cases, the sampling method also affects the style and color performance of the image.<\/li>\n<\/ul>\n<p>IV. Conclusion<\/p>\n<p>It is recommended that you try different iteration steps and samplers using the same cue words and parameters to see for yourself the impact of changes in these parameters.<\/p>\n<p>Above is our comprehensive analysis of the Stable Diffusion parameter.

SD Learning and Painting Principle 1, Learning Principle Stable Diffusion learns by adding noise to images. This process can be seen as the process by which AI gradually \u201cremembers\u201d image characteristics. By gradually increasing the noise, AI learns how to recover original images from the noise. The principle of painting is, contrary to the learning process, painting is a noise-free process.
