Beyond Text: Advanced Retrieval-Augmented Generation for Complex and Multimodal Data

Retrieval-Augmented Generation (RAG) is a cutting-edge framework that combines retrieval-based methods with generative models to enhance the accuracy and relevance of responses by retrieving relevant information from a knowledge base before generating answers. Its significance lies in its ability to handle complex, knowledge-intensive tasks like question answering, document summarization, and conversational AI, making it a powerful tool for applications in healthcare, finance, education, and more.

As RAG rapidly evolves, it is being applied to increasingly diverse domains, requiring it to handle broader types of data, including text, images, tables, graphs, and time-series data. However, this expansion introduces challenges such as cross-modal retrieval, unified representation learning, data fusion, scalability, noise handling, and evaluation.

This tutorial will cover recent progress in retrieval augmented generation, including fundamental concepts, technical advances for complex data, corresponding applications, and evaluation.
