Kernel Ridge Regression with Cholesky Inverse Training Using JavaScript -- Visual Studio Magazine Dr. James McCaffrey presents a complete end-to-end demonstration of the kernel ridge regression technique to predict a single numeric value, implemented using JavaScript. The demo trains the model using kernel matrix inverse (Cholesky decomposition). There is no single best machine learning regression technique, but when kernel ridge regression prediction works, it is often highly accurate.

Kernel ridge regression with an RBF kernel and L2 regularization achieves 99.5% train accuracy and 95.0% test accuracy in this JavaScript demo using Cholesky-based kernel matrix inverse training.

AI Faceoff: Customized VS Code Commands -- Visual Studio Magazine After a long-unused VS Code extension stopped working, I compared multiple AI tools to recreate the same HTML-wrapping workflow using built-in snippets and keybindings. Mileage among the systems varied. And the approach I used for my text-writing use case can be easily translated to coding scenarios.

When htmltagwrap broke in VS Code 1.107.1, the fix wasn’t “build an extension.”

In this article, David Ramel shows how built-in snippets and keyboard shortcuts can replicate htmltagwrap-style HTML wrapping, without writing a new extension.
