Frequently Asked Questions (FAQs)
What is RAG (Retrieval Augmented Generation)?
RAG, or also called Retrieval Augmented Generation, also sometimes called model fine-tuning, is a technique that combines information retrieval, deep learning, and text generation to improve the performance and accuracy of natural language processing tasks.
Retrieval Augmented Generation models retrieve relevant information from a large corpus of documents and use this information to generate more informed and accurate responses.
This course will help you understand how to preprocess different types of documents, which is a crucial step in setting up a Retrieval Augmented Generation system.
What Is Unstructured Data?
Unstructured data is any data that doesn’t fit neatly into traditional databases or spreadsheets. Think text documents, images, PDFs, and HTML files. These data types need a predefined structure, making them tricky to process but rich with potential insights.
In our course at AI for Developers, we teach you how to turn this chaotic data into a goldmine of information for your LLM applications with the help of Retrieval Augmented Generation.
What is an LLM Application, and how is it related to Retrieval Augmented Generation?
An LLM application, or large language model application, is software that utilizes large language models to perform various natural language processing tasks. These tasks include text generation, translation, summarization, and question-answering.
These applications leverage the vast amounts of data and sophisticated algorithms of LLMs to understand and generate human-like text.
Retrieval Augmented Generation (RAG) enhances Large Language Models (LLM) applications by incorporating external knowledge bases into the generation process.
By retrieving relevant information from a large corpus of documents and integrating it into the language model’s input, Retrieval Augmented Generation improves the accuracy and relevance of the responses generated by LLM applications.
This course teaches you how to preprocess and organize data to effectively implement RAG in LLM applications, enhancing their performance and capabilities.
How Does RAG Enhance Natural Language Processing?
Retrieval Augmented Generation enhances natural language processing by integrating external knowledge into the generation process. RAG allows models to provide more accurate and contextually relevant responses by accessing vast information stored in a database.
This course covers preprocessing and normalizing various unstructured data types, enabling efficient retrieval and integration into RAG systems.
Who is this course for?
