roughViz.js

Reusable JavaScript library for creating sketchy/hand-drawn styled charts in the browser, based on D3v5 & roughjs.

Train, Test, And Validation Sets

Learn why it is best practice to split your data into training, testing, and validation sets, and explore the utility of each with a live machine learning model.

The Good, the Rad, and the Gnarly

'An exploration into the music of skateboarding'. Visual essay I created for The Pudding.

ROC & AUC

A visual, interactive explanation of Receiver Operating Characteristic (ROC) Curves and Area Under The Curve (AUC).

Decision Trees

An explanation of the Decision Tree algorithm in machine learning: how the tree makes its splits, the concepts of Entropy and Information Gain, and why going too deep is problematic.

Precision & Recall

When it comes to evaluating classification models, accuracy is often a poor metric. This article covers two common alternatives, Precision and Recall, as well as the F1-score and Confusion Matrices.

Random Forest

Learn how the majority vote and well-placed randomness can extend the decision tree model to one of machine learning's most widely-used algorithms, the Random Forest.

Double Descent: A Visual Introduction

An introduction to the double descent phenomenon in modern machine learning: what it is, how it relates to the bias-variance tradeoff, and a theory of what lies behind.

Double Descent: A Mathematical Explanation

A mathematical explanation of the double descent phenomenon, building on the cubic spline example introduced in the prior article.

The Bias Variance Tradeoff

Understand the tradeoff between under- and over-fitting models, how it relates to bias and variance, and explore interactive examples related to LOESS and KNN.

Datasets

A curated list of some cool datasets that I created.

The Permutation Test

A 'scrolly-telling' visual tutorial of statistical testing with hand-drawn SVG aesthetics.

Sperm Hero

A game where you control a sperm cell with your head and dodge various forms of birth control.

The Networks of Skateboarding Filmmakers

A look into the networks (graphs) of skateboarding filmmakers and the skateboarders they film.

4PLYMAG: All The Gall

An analysis of Fred Gall's prolific skateboarding career.

Nested Machine Learning Workflows

An introduction to nested machine learning workflows in R with tidyr & purrr.

4PLYMAG: Eric Koston

A look and analysis the professional skateboarding career of Eric Koston.

Jenkem Mag
