Generative AI 101

What Is Generative AI? 

The term “generative AI,” or “generative artificial intelligence,” describes a subclass of artificial intelligence technologies intended to produce content that resembles the inventiveness of humans. The content may consist of code, text, pictures, music, movies, and even completely interactive settings. In contrast to conventional AI systems, which concentrate on identifying trends or drawing conclusions from preexisting data, generative AI actively creates new data.

Fundamentally, generative AI models use enormous volumes of data to identify patterns, styles, and structures before using this information to create original content. Depending on the model’s purpose and design, the outcomes can be anything from creative and abstract to incredibly realistic.

Here is an example of content types that generative AI can create. 

  • Text (e.g., articles, poems, stories)
  • Images (e.g., art, portraits)
  • Videos (e.g., animations, deepfake content)
  • Music (e.g., compositions, soundscapes)
  • Code (e.g., programming scripts)

Key Features of Generative AI

Content Creation

Generative AI produces new and original content. For instance, it can write essays, generate artwork, compose music, or create synthetic voices.

Learning from Data

Generative AI models are trained on vast datasets. They learn the patterns, structures, and nuances of the data, enabling them to generate realistic outputs.

Interactive and Adaptive

These models can adapt their outputs based on user inputs, making them highly interactive. For example, ChatGPT adjusts its responses based on conversational context.

Human-like Innovative Thinking

By using enormous datasets to create original designs, narratives, or solutions, generative AI imitates human creativity.

Interaction

By enabling interactive features like conversational interfaces, real-time art production, or personalized tales, generative AI improves user engagement.

Awareness of Context

Context is understood and included in outputs by contemporary generative AI models, such as ChatGPT, which makes the information pertinent and cohesive.

Scalability

Generative AI requires very few more resources to create an almost infinite amount of content once it has been trained.

How Does Generative AI Work

Generative AI features complex models that mimic the functions of a human brain and are used as the origin of different generative AI applications. So, these models are also called foundation models. 

These models learn to simulate human creativity through training on large data sets that make them capable of producing high-quality and original content. 

The function of generative AI generally includes three steps – foundation model development, fine-tuning, and retrieval augmented generation. These steps further have sub-steps that contribute to enhancing the model’s ability. 

The foundation of generative AI is sophisticated machine learning methods, mainly utilizing neural networks. Here’s a detailed explanation of how it functions.

Foundation Model Development 

Foundation Gen AI models are trained with large datasets, and these are the foundation of various generative AI applications. One example of foundation generative AI models is large language models (LLMs) that are used for text generation. 

Generative AI uses deep learning models such as CNNs and RNNs. Convolutional Neural Networks, or CNNs, are used for image and video creation, while Recurrent Neural Networks, or RNNs, are used for text and sequential data generation.   

Data Collection and Training 

Large datasets are necessary for training generative AI. For instance:

Large text corpora from books, websites, and articles are used to train a text generator like ChatGPT.

DALL·E is an image generator that learns from databases of labelled images.

These datasets give the model the ability to find and understand links, patterns, and structures in the data.

Fine Tuning and Optimization 

Following initial training, generative AI models are refined using tasks or data unique to a certain domain. A base language model, for example, can be modified to generate legal or medical texts.

Retrieval Augmented Generation (RAG) 

In this step, generative AI models work with external data retrieval mechanisms to use real-time data from external sources in the content generation process. This enables Generative AI models to enhance the quality and relevance of generated content. This benefits generative AI models, allowing the production of high-quality content as per the latest trends. Also, this process serves as the basis of dynamic content creation.    

Generation Process 

Generative AI may generate content once it has been trained by exploiting learnt patterns to generate pertinent outputs from prompts or seeds as input. 

For instance, in text generation, the following word or sentence is predicted using previous context.

Using learnt visual styles as a guide, Gen AI creates pixel patterns for image generation. 

Types of Generative AI Models

Generative AI models are available in various types, each with their unique style of content creation. Let’s discuss the types of generative AI models and their functionalities. 

Generative Adversarial Networks (GANs) 

Generative adversarial networks include two neural networks – one is a Generator, and the other one is a Discriminator. In this system, the generator creates data, and the discriminator evaluates its authenticity and sends feedback to the generator. 

This process continues until the generated data is identical to real data. This way, GANs operate to create authentic and realistic data.   

Variational Autoencoders (VAEs) 

VAEs encode the input data into a compressed representation and then generate new content from it. In this process, the generative AI model learns the internal structure of the dataset to generate high-quality content. Variational autoencoders are applicable in areas where variations of existing data are needed. 

Diffusion Models 

This type of Gen AI model gradually adds noise to the input data and reverses the process to produce new coherent data. 

Transformers 

Transformers are a type of generative AI model that understands the context and generates an output accordingly. Examples of transformers are chatbots and content creation.  

Applications of Generative AI
