47. Generative Adversarial Nets

Learning objectives

• Introduce generative adversarial networks

• You can add notes on each slide with blocks like this!
• Load a deck in the browser and type “s” to see these notes.

Definition

• “Generative AI is a form of artificial intelligence that is designed to generate content, including text, images, video and music. It uses large language models and algorithms to analyze patterns in datasets to mimic the style or structure of specific types of content.”
