Sponsored LinkTwitter Spaces: Responsible and Trustworthy AIListen in on a live Twitter Spaces at 9:30am PST on Wednesday, August 17, featuring Ben Lorica of Gradient Flow, Andrew Burt of bnh.ai, and Bob Friday of Juniper Networks. The conversation will discuss what it takes to get to mature adoption of AI in the enterprise, and the role trust plays throughout. Tutorials, Projects & OpinionsThe Singular Value DecompositionThe singular value decomposition is something of a Swiss Army knife of linear algebra. It's a popular way to compute a principal component analysis and it's also used for linear projections, linear regressions, and much more. This is a fantastic deep dive that shows how it works and the variety of things you can do with it. How the NYT uses ML to make its paywall smarterWhen The New York Times first launched its paywall, the meter count was the same for all users. A lot's changed since then and its paywall now uses a causal machine learning model called the Dynamic Meter to set personalized meter limits. Here's how it works. Bayesian A/B tests with millions of observationsData scientists are increasingly using Bayesian methods but at scale, Bayesian methods can be slow. This post walks through the issues and shows how the authors got a proof-of-concept A/B test pipeline to work very fast even with very large numbers of observations. Excel is Pretty Dang CoolWhether you love it or hate it, there's a lot that Excel can do. Here are some lesser known features and if you're in for a good debate, check out the discussion on Hacker News >> Logistic Regression - Regression for ClassificationLogistic regression is a supervised learning algorithm that can be used to classify data into categories, or classes, by predicting the probability that an observation falls into a particular class based on its features. This is a short visual explainer that makes it easy to see how it works. ResourcesMachine Learning ZoomcampGreat resource for getting started in Machine Learning. Covers a wide variety of topics with lecture videos, slides, assignments and a Slack channel. The next course begins in September. Free. Data VisualizationPyramid Plots in ggplot2Pyramid plots are often used to compare the ages of different populations. They're intuitive to understand but can be more complicated to build than you might think. This is a nice tutorial that shows a simple way to make them using ggplot2. Aquarel 🎨Aquarel is a lightweight templating engine and wrapper for Matplotlibs' rcparams to simplify styling plots. Aquarel templates can be defined programmatically and be serialized and shared in a JSON format. Was this email forwarded to you? Sign up here >> |
