RAG From Scratch in Java
📰 Dev.to · Puneet Gupta
Learn to build a retrieval-augmented generation (RAG) model from scratch in Java, understanding key components like chunking, embeddings, and vector search.
Action Steps
- Build a chunking algorithm to split input text into manageable pieces using Java.
- Create a custom embedding layer to convert text chunks into numerical vectors.
- Implement a hand-rolled cosine-similarity vector search to find relevant chunks.
- Develop a reranking system to refine the search results based on relevance and context.
- Compare the performance of the RAG model with a larger context window to understand its advantages.
