How to learn Generative AI models in 2025
How to learn Generative AI
Generative AI (GenAI) is transforming industries by enabling machines to create text, images, audio, code, and more. For a graduate student eager to learn GenAI, it’s essential to build a solid understanding of the underlying models, tools, and techniques. This tutorial will guide you through a structured learning approach, leveraging key models mentioned earlier.
1. Fundamentals of Generative AI
What is Generative AI?
Generative AI is a type of artificial intelligence focused on creating new content, such as text, images, audio, video, and even code, by learning patterns from existing data. Unlike traditional AI, which is designed to analyze data and make predictions, generative AI aims to produce original outputs that mimic human creativity.
How Does Generative AI Work?
Generative AI models are typically powered by advanced machine learning algorithms, particularly deep learning. These models learn from large datasets to understand patterns, relationships, and structures, enabling them to generate novel content. Key techniques include:
