Generative Artificial Intelligence | Introduction

Introduction of Generative Artificial Intelligence 

The advancement of artificial intelligence (AI) has resulted in the emergence of a remarkable field known as generative AI. With the ability to replicate human creativity and inventiveness, this innovative area sits at the intersection of art, science, and technology.

What is Generative AI?  

Generative AI is a type of AI technology that allows machines to generate new content, data, or outputs that are like human-created content. It uses large datasets to learn the underlying structure and characteristics of the data, enabling it to produce original and contextually relevant outputs. This differs from traditional AI, which focuses on recognizing patterns and making predictions based on existing data. Generative AI can generate various data types, including text, images, sounds, animations, and 3D models, and it can create entirely new data based on the patterns it has learned.

Evolution of Generative AI  

Here's a brief history of generative AI

• 1950s - Markov chains were created as an early form of generative AI for generating data sequences.  

• 1960s - Joseph Weizenbaum developed ELIZA, the first chatbot.

How Does Generative AI Work?

Generative AI models utilize neural networks to identify patterns and structures within existing data, enabling them to generate unique and original content. One of the significant breakthroughs of generative AI models is the ability to use unsupervised or semi-supervised learning techniques to train them. This has allowed organizations to easily and quickly leverage large amounts of unlabeled data to create foundation models. As the name implies, foundation models serve as a basis for AI systems that can perform multiple tasks.

Types of Generative AI Models and LLM Model Training

Examples of foundation models include GPT-3 and Stable Diffusion, which allow users to harness the power of language. For instance, popular applications like ChatGPT, which uses GPT-3, enable users to generate a paragraph or content based on a text request. GPT-4 generates text by accepting both text and image inputs. On the other hand, stable diffusion allows users to generate photorealistic images by providing text input.
