ISSUE 453 · September 19, 2023TrendsCentaurs and Cyborgs on the Jagged FrontierA recent study found that consultants using GPT-4 outperformed those who did not, by a LOT. But AI is weird. No one really knows the full range of capabilities of the most advanced LLMs, like GPT-4. No one really knows the best ways to use them, or the conditions under which they fail. And, unless you use AI a lot, you won’t know which is which. This is a key post to help you get the most out of these new tools.

This post walks through five variations of JOIN, with examples that make it easy to see how they work and why you'd choose one over another. What Key is 'Hey Joe' in?Nice tutorial that combines concepts from music, mathematics and physics. Ultimately, it shows how to determine the tonality of a given set of notes using a mathematical model for tonality known as the Spiral Representation. There's a lot here, including a Jupyter notebook, useful diagrams, and linked references along the way. The intuition behind the Dirichlet distributionAndrew Heiss's latest post explores the Dirichlet distribution using an intuition-based approach that uses lots of visuals and not much math. Geolocating Sydney’s weirdest propertyNo matter who you are or where you are, there is probably enough data for a sufficiently motivated person to find you. In this post, Dean Marchiori shows how to use R and Open Street Map to geolocate a property in Sydney from just a photo and a tweet.
