Featured Challenge:
#187 — Bayesian Text Classification

In this coding challenge, I struggle my way through implementing a Naive Bayes text classifier in JavaScript using p5.js. I explain Bayes' theorem, demonstrate word frequency analysis, implement Laplacian smoothing, and build a working sentiment classifier that runs entirely in the browser.

Learn to create your own climate spiral using p5.js and temperature data. Originally designed by the climate scientist Ed Hawkins, the climate spiral is a visual representation of the changing temperatures over time, illustrating the urgent need to address climate change.

In this coding challenge, I follow up on the Earthquake Data Visualization challenge and create a 3D version in Processing(Java) using spherical coordinates. I also discuss some 3D vector math including the cross product.
