Make better choices with AI-assisted A/B testing
In this post, I will show how to use A/B testing to rank thousands of qualitative items, made easier through automation by large language models (LLMs). The ELO algorithm The ELO algorithm, originally designed for ranking chess players, is a well known method for determining rankings through a series of head-to-head matches. The algorithm assigns…

How to Create Animated 3D Plots in Python
Matplotlib has become the standard plotting library in Python. This is thanks to its simple API and NumPy/SciPy integration, making it easy to add interactive plots to any code. In this post, I will walk through how to make animated 3D plots in Matplotlib, and how to export them as high quality GIFs. RGB Color…
Exploring Latent Word Vectors using Path Finding
In my previous post, I created a product recommendation system using word embeddings. Today, we’ll take it a step further and explore how we can use these vectors to find the shortest path between pairs of words. Dijkstra’s algorithm Dijkstra’s algorithm is a method for finding the shortest path between any two vertices of a…
