Keywords

💡AI

Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions. In the context of the video, AI is used to learn and render characters or idols, indicating the application of machine learning algorithms to generate images or models based on provided data.

💡Steady Diffusion

Steady Diffusion is a type of AI model used for generating images or videos from textual descriptions or existing images. It is part of a broader category of AI known as Generative Adversarial Networks (GANs). In the video, the term is used to describe the technology that enables users to create digital representations of characters or idols by learning from example images.

💡Google Colaboratory

Google Colaboratory, often shortened to Colab, is a cloud-based platform for machine learning and data analysis. It provides free access to GPUs and TPUs for users to run their code.
