Linear Regression

Interactively learn about linear regression models as they're commonly used in the context of machine learning.

The Good, the Rad, and the Gnarly

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

Logistic Regression

Learn how logistic regression can be used for binary classification in machine learning through an interactive example.

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.

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.
