Modern artificial intelligence solutions utilize complex algorithms to perform tasks like content generation, data analysis, and comprehension. These technologies enable machines to communicate with human users naturally and generate various forms of text based on existing knowledge.

For those new to AI, understanding the complex terminology can be challenging. Artificial Intelligence (AI), Large Language Models (LLMs), Natural Language Processing (NLP), and Generative AI are all related yet distinct in their functions and applications within computer science. Recognizing these differences is crucial.

In this guide, we will delve into Generative AI, LLMs, and NLP, exploring their differences along with the best examples of these technologies and their potential to enhance business operations.

Let’s start with understanding LLM, NLP and Generative AI.

What is LLM?

Large Language Models (LLMs) are cutting-edge AI systems that generate human-like text by utilizing extensive training data and deep learning techniques. These models rely on vast datasets to understand and produce natural language. By using the transformer architecture, LLMs apply self-attention mechanisms that process each word in relation to all other words in a sentence.

Examples of LLMs

Examples of LLMs

GPT-4: OpenAI's GPT-4, an extension of GPT-3, is one of the largest LLM models. It is trained on vast data for higher accuracy and the ability to process 25,000 words. It is estimated to have around 1.76 trillion parameters.
GLaM (Generalist Language Model): GLaM, developed by Google, is an advanced AI model with 1.2 trillion parameters. It is designed to generate human-like responses and simulate text-based conversations using extensive training on diverse internet text data.
BERT (Bidirectional Encoder Representations from Transformers): Google's BERT is a 340-million parameter LLM that excels in natural language processing, used for text classification, entity recognition, and question-answering.
LLaMA (Large Language Model Meta AI): Meta's LLaMA (Large Language Model Meta AI) is an NLP model with billions of parameters trained in 20 languages, available for non-commercial use. It excels in conversation and creative writing, using complex algorithms to generate coherent text.

What is NLP (Natural Language Processing)?

Natural Language Processing (NLP) falls under the umbrella of artificial intelligence that aims to enable computers to understand and produce human language. It encompasses the ability to comprehend, analyze, and manipulate human language. NLP combines computational linguistics, focusing on rule-based language modeling, with machine learning models to execute tasks such as translation, sentiment analysis, and identifying topics within text. It is integral to applications like smart assistants, chatbots, and language translation software.

NLP is pivotal in performing tasks such as:

NLP

Text Classification: It involves organizing texts into different categories based on their content. Classifying news stories according to topics like sports, politics, and technology is one example.
Sentiment Analysis: It is a technique used to assess written content and determine whether it conveys a specific emotional tone. Sentiment analysis is a commonly used tool to gauge public sentiment towards a product or service on review sites or social media platforms.
Language Translation: It enables seamless communication across different languages and enhances global accessibility to information. Language translation utilizes advanced natural language processing models to accurately translate text from one language to another.
Question Answering: The objective of question answering systems is to automatically respond to questions posed by humans using natural language processing (NLP). To accomplish this, it is essential to have a clear understanding of the query's context and the ability to extract relevant information from a specific source.
Chatbot Development: It involves creating conversational agents (chatbots) that can interact with customers naturally. They provide assistance with customer service, collect data, and guide users through website navigation.

What is Generative AI?

Generative AI refers to artificial intelligence designed to develop models capable of generating original content such as images, music, video, and text. Unlike LLMs that focus on language-based data, Generative AI trains algorithms on vast datasets to learn inherent patterns and structures. Post-training, these algorithms replicate data styles, characteristics, and distribution of the data to produce new content.

Core techniques involve recurrent neural networks (RNNs) and generative adversarial networks (GANs), with transformer architecture (T in ChatGPT) serving as a fundamental component in evolving this technology.

Types of Generative AI

Types of Generative AI

Here’s a list of popular types of GenAI

1. Generative adversarial networks (GAN): GANs analyze input data like human faces to create entirely new and realistic outputs, even generating images of people who don't exist. They are integral to text-to-image technologies like DALL-E.
2. Diffusion model: Adds noise to data for learning reversibility, used in tasks like generating images from text descriptions and manipulating visuals.
3. Transformer model: Transformers in generative AI excel at understanding connections between words, enabling the generation of coherent text and creative content from extensive datasets.
4. Neural radiance fields (NeRF): Generates accurate 3D models from multiple 2D images, applicable in fields like architecture and robotics.
5. Variational Autoencoders (VAE): Encodes and decodes data to create new content across various mediums like images, music, and text, using learned patterns for innovative outputs.
