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.

3D rendering

Can I draw and rotate a 3D cube using Processing's 2D renderer with just some math?!?! Yes! Watch to learn more about rotation and projection matrices along with perspective and orthographic projection!

3D Rendering with Rotation and Projection

Getting tied up in 3D Knots in Processing is loads of fun! Thank you to Paul Bourke for the helpful reference and formulae!
