Insights

Data’s day of reckoning

Data is sometimes said to be the "new oil" but for most businesses, that analogy doesn't work. In the most successful of data organizations, data might burn bright but, as Benn Stancil puts it here, in most businesses, data burns more like peat moss. Here are some reasons why, with some ideas for all the median businesses.

Tutorials, Projects & Opinions

How Federated Learning Protects Privacy

Most machine learning models are trained by collecting vast amounts of data on a central server. This is a great visual explainer that shows how federated learning makes it possible to train models without any user's raw data leaving their device.

Forecasting with Structural AR Timeseries

The strength of a Bayesian model is largely the flexibility it offers for different modeling tasks. In this tutorial, Nathaniel Forde shows how to fit and predict a range of auto-regressive structural timeseries models and how to predict future observations of the models.

Method Chaining in Pandas: Bad Form Or a Recipe For Success?

Matt Harrison has written books on pandas and Python and regularly trains data science teams at top companies. And yet, his code is sometimes met with derision online. In this interview, he explores his approach to code, how to think about method chaining, and what separates naive code from good code.

Using Functional Analysis to Model Air Pollution Data

Functional analysis is one approach to understand how your data changes within a given timeframe, such as a day, or between timeframes such as many days. This is an easy-to-follow tutorial that shows how to apply functional analysis to some messy air pollution data using R.
Nicola Rennie

How I learn machine learning

In a rapidly evolving field like machine learning, you need to figure out what works for you to navigate the never-ending task of staying up to date. In her latest post, Vicki Boykis shares her own process, including lots of links and resources along the way.

Tools & Code

Debirdify

This is a great tool if you're looking for Mastodon accounts to follow and want something more nuanced than a haphazard list of user handles. Debirdify searches a specific Twitter user's Lists and/or Followed Accounts for associated Mastodon handles and returns a Mastodon-friendly csv file.

Galileo’s Telescopic Discoveries:
Thinking Visually in the History of Science

People who are trained in visual thinking are able to see things that others miss. When Galileo discovered Jupiter's moons, he did so because he was seeing with the eyes of an artist. This is a great capstone presentation from the recent VIS2022 conference that explores how the process of visualization gives superpowers to the sciences.
