NuScienta - AI & Data Experts on Instagram: "AI video generation is typically powered by machine learning models called diffusion models. Diffusion models are models that generate data by learning how to reverse a random noising process. During training, random noise is added step by step to images or video frames until they become practically pure noise, and the model learns to predict and remove that noise at each step. At inference, the process starts from pure noise and the model iteratively
