#Embedding

Separate ingestion from retrieval, handle HNSW contention, and build a runnable PostgreSQL boundary that won't collapse under concurrent load.

New embedding, parsing, and reranking models promise smarter agentic RAG workflows

Recommender systems (RecSys) are one of the most ubiquitous machine learning problems in the consumer internet industry yet notoriously difficult to train and…

Keyword research told you it was guessing. A vector score doesn’t, and that’s where the real mistake lives.

Watson's death last month prompted sci-fi columnist Emily H. Wilson to read his acclaimed 1973 debut and find out what she'd been missing. She found it fascinating – but reflective of its time

Most businesses have a search problem. Not a Google-scale problem. An operational...

In this article, you will learn how to implement vector similarity search in PostgreSQL using the pgvector extension, allowing you to find semantically similar results based on meaning rather than keyword matching.

In the previous post, we saw some basic methodologies under sparse embeddings. In that, term...

Build production-ready recommendation systems using embeddings, vector search, hybrid filtering, and LLM-powered personalization.

I see developers trying to build "AI Chatbots" that know about their specific company data. They want...

Retrieval-Augmented Generation is now the default architecture for adding knowledge to LLM-powered...

Learn embeddings techniques for semantic search, clustering, and similarity matching with vector databases.

I spent last weekend building a local vector cache for my AI coding assistant. It took exactly 46...

What is chunking Chunking is the process of breaking data into smaller pieces called...

From Dev.to - machinelearning: # Why "drift_score = 0.0" Is Not Yet Evidence of Semantic Stability — and What Your n=251 vs cap=200 Mismatch Actually Costs by: Eyoel Nebiyu

Cut embeddings 1536 → 256 without breaking recall. Matryoshka native truncation, PCA on legacy models, recall curves, decision rule.

A few months ago I was staring at a spreadsheet trying to figure out why our unit economics looked...

You can read the original post over on lukaswalter.dev. Developers often start RAG apps using...

The embedding model decides what your retriever can find. The reranker decides what makes it to the LLM. By 2026 the production patterns for picking and pairing these two have stabilized, and most teams are still leaving real recall on the table because…

Local embeddings vs hosted APIs in 2026. Crossover math, where each one wins, and the cases where shipping your own model is the cheaper bet.
