Diffuusiopohjaiset

Diffuusiopohjaiset, often translated as diffusion-based, refers to a category of models that operate on the principle of diffusion. These models are characterized by a process that gradually adds noise to data until it becomes indistinguishable from random noise. Subsequently, a reverse process is employed to denoise the data, ultimately reconstructing the original information or generating new data that resembles the training distribution.

In machine learning, diffusion models have gained significant traction, particularly in the field of generative modeling. They are capable of producing high-quality and diverse outputs, including images, audio, and text. The core idea involves learning a sequence of denoising steps. During training, the model learns to reverse this diffusion process, effectively learning to remove noise at various levels.

The mathematical framework behind diffusion models typically involves stochastic differential equations or Markov chains. These models excel at capturing complex data distributions due to their iterative nature, allowing them to learn intricate details. Their application spans various domains, from image synthesis and editing to data augmentation and anomaly detection. The success of diffuusiopohjaiset approaches is attributed to their ability to generate coherent and realistic samples, often outperforming previous generative methods in terms of sample quality and diversity.
