Instruction Aware Embeddings
Why Your Retriever is Failing and How Context Can Save It Imagine asking “I want to buy apple” – do you mean Apple Inc. stock, the latest iPhone, or simply fruit? Without context, your retriever may serve you the wrong results. 1. What Is the Problem in Your Retriever & Embedding? Modern retrievers map queries and documents into high-dimensional vectors (embeddings) and rank by cosine similarity. But when a query is ambiguous, plain embeddings struggle:...
Improving Retrieval in RAG (via Recall, Precision, and NDCG)
Improving Retrieval in RAG (via Recall, Precision, and NDCG) Introduction Retrieval-Augmented Generation (RAG) is the superhero sidekick that grounds your Large Language Model (LLM) in cold, hard facts. But here’s the dirty secret: if your retrieval sucks, your RAG system is just a fancy chatbot with a broken brain. Weak retrieval = missed documents, irrelevant results, and rankings that make no sense. This guide cuts through the noise. You’ll learn how to turbocharge your RAG retrieval with a no-fluff, step-by-step approach to maximize recall, sharpen precision, and nail NDCG....

Essential Database Design: Five Fields Every Table Must Have
Essential Fields Be it relational or not, every table should have these 5 fields: created_at (default now()) updated_at (default now()) deleted_at (default null) created_by (not null) updated_by (not null) Just to be clear, every table should have these 5 fields and not must. Adding these fields have other side-effects such as bloat, performance and disk size. But, if you’re having these problems, i hope you’re profitable. Why should you include this fields ?...
Speeding up the GPT - KV cache
The common optimization trick for speeding up transformer inference is KV caching 1 2. This technique is so prominent that huggingface library has use_cache flag is enabled by default 6. A few days ago, I read an awesome blog post on GPT in 60 Lines of NumPy. So, i thought, why not extend it to use the KV cache technique? So, let’s roll up our sleeves and start working on it....
