Chunk Size as an Experimental Variable in RAG Systems

the sorts of answers we expect today from Retrieval-Augmented Generation (RAG) systems. Over the past few years, RAG has develop into one in all the central architectural constructing blocks for knowledge-based language models: As...

The Geometry of Laziness: What Angles Reveal About AI Hallucinations

a few failure that was something interesting. For months, I — together with a whole lot of others — have tried to construct a neural network that might learn to detect when AI systems...

The best way to Do Evals on a Bloated RAG Pipeline

to Constructing an Overengineered Retrieval System. That one was about constructing the whole system. This one is about doing the evals for it. Within the previous article, I went through different parts of a RAG...

Six Lessons Learned Constructing RAG Systems in Production

couple of years, RAG has became a type of credibility signal within the AI field. If an organization desires to look serious to investors, clients, and even its own leadership, it’s now expected...

When (Not) to Use Vector DB

. They solve an actual problem, and in lots of cases, they're the precise selection for RAG systems. But here’s the thing: simply because you’re using embeddings doesn’t mean you a vector...

Construct an Over-Engineered Retrieval System

you’ll encounter when doing AI engineering work is that there’s no real blueprint to follow. Yes, for probably the most basic parts of retrieval (the “R” in RAG), you'll be able to chunk documents,...

The right way to Perform Agentic Information Retrieval

is a crucial task that's critical to attain, with the vast amount of content available today. An information retrieval task is, for instance, each time you Google something or ask ChatGPT for a...

Tips on how to Evaluate Retrieval Quality in RAG Pipelines (Part 3): DCG@k and NDCG@k

: 👉 👉 of my post series on retrieval evaluation measures for RAG pipelines, we took an in depth have a look at the binary retrieval evaluation metrics. More specifically, in Part 1, we went...
