MIT CSAIL Researcher Explains: AI Image Generators

Hi everyone, I'm Elin Dew, a PhD student at the MIT Computer Science and AI Laboratory (CSAIL), researching how to construct intelligent robot agents. Today, I'll be explaining how AI image generators work.

Large text-guided diffusion models are trained on vast datasets of images and captions from the internet, enabling them to reconstruct and generate images based on text prompts. These models are trained on millions of image-text pairs and can generate images similar to those found online.

The impact of diffusion models lies in the extensive training data and computational power used to train them. With significant computational resources, these models can be trained at large scales, leading to remarkable achievements in image generation.

While there are no copyright restrictions on AI-generated images, some companies have been selling AI artwork for considerable sums. However, concerns arise regarding copyright infringement and the need for licensing regulations to govern the sale of AI-generated artworks.

Preventing harmful or offensive images generated by AI models, particularly in open-source programs, remains a challenge. Curating training data meticulously and carefully selecting images can help mitigate this issue, although it is still a significant concern for many companies.

Generative AI holds potential beyond image or text generation, with applications in robotics, control systems, protein synthesis, and molecular design. Researchers have explored using generative models for controlling robotic actions, demonstrating the versatility of these models across various domains.

In conclusion, AI image generators, such as large text-guided diffusion models, are powerful tools with diverse applications, ranging from art creation to robotics and beyond.
