A Mathematical Introduction to Large Language Models. The main text for this tutorial is the latest (draft) version of "Speech and Language Processing" by Dan Jurafsky and James H. Martin. It is not yet published as of 2026 — but already an excellent textbook. Here, I explain the LLM system and, more specifically, the prerequisites of understanding transformers. My goal is to bridge the mathematics of LLMs and, generally, Information Retrieval with more foundational mathematics. This tutorial is being updated continuously. This is the first article in my Substack on the Mathematics of Information, and there's more in the drafts that will soon be published. Thank you for reading. https://lnkd.in/eGCbFgEF

The Bignumber AI Search Engine. I’d like to introduce you to the search engine created at Bignumber for research and education in the quantitative fields. This search engine is about finding correct answers from credible sources — faster and with greater clarity. What’s the story? I initially developed this AI search engine for my own mathematics consulting work. LLMs are excellent for general information, but they usually don’t pull references from credible sources — or at all. They also produce long, unclear text unless you keep refining prompts. I needed immediate access to the right mathematical definitions from the right references. This was a hassle. This is the problem I’m focused on solving: making complex topics not complex. I’m now deploying this engine for everyone, especially those in research and education in technical fields — engineering, physics, finance, statistics, and the like. Search results include precise references. The engine uses a corpus indexed by Bignumber, but suggested alternative references are provided. It also goes beyond the corpus with deep research across academic journals, white papers, and other quantitative literature. I invite you to try Bignumber and share your feedback — especially if you work in research, science, engineering, mathematics, or finance! https://www.bignumber.io/
