Session brief
Retrieval Augmented Generation in the Wild: Anton Troynikov
Overview
This talk explores the limitations of basic retrieval-augmented generation (RAG) loops and argues for more sophisticated memory systems to power advanced AI applications. It highlights the need for RAG systems that can incorporate human feedback, self-update based on agent interactions, and dynamically adapt to evolving data. The core thesis is that future powerful AI applications will require retrieval systems far beyond simple search indexes.
Who should watch
- AI engineers building RAG applications
- Product managers exploring advanced AI features
- Developers seeking to improve AI memory and data handling
- Anyone interested in the evolution of retrieval systems beyond basic search
Key takeaways
- Standard RAG loops, while foundational, are insufficient for more powerful AI applications.
- Human feedback is crucial for adapting embedding models to specific tasks and user needs.
- AI agents require memory systems that support self-updates based on world interactions, enabling dynamic data adaptation.
- Retrieval systems must not only return relevant information but also exclude irrelevant data to prevent performance degradation.
- Evaluating embedding models for specific datasets is challenging; custom datasets and human feedback are key.
- Chunking strategies significantly impact retrieval relevancy, and experimental methods like using model perplexity for boundary detection are being explored.
- Determining the relevance of retrieved results algorithmically, based on the dataset and task, is a promising area for future development.
- The development of multimodal RAG systems necessitates new approaches to evaluating relevance across different data types like images and voice.
Notable quotes
*The memory that you're using for your rag application needs to be able to support this sort of human feedback.*
*The most powerful things that you'll be able to build with AI in the future require much more a much more capable retrieval system than one that only supports a search index.*
*Distractors in the model context cause the performance of the entire AI based application to fall off a cliff.*
