Right now, in Visual Studio, you can create a solution that takes a single UI with its code and shares it across Windows, Android, macOS, iOS and web browsers. It's not a perfect cross-platform solution (yet), but it's here now.
Dr. James McCaffrey of Microsoft Research presents the fundamental concepts of tensors necessary to establish a solid foundation for learning how to create PyTorch neural networks, based on his teaching many PyTorch training classes at work.

Dr. James McCaffrey of Microsoft Research uses a complete demo program, samples and screenshots to explains how to install the Python language and the PyTorch library on Windows, and how to create and run a minimal, but complete, neural network classifier.

Clustering non-numeric -- or categorial -- data is surprisingly difficult, but it's explained here by resident data scientist Dr. James McCaffrey of Microsoft Research, who provides all the code you need for a complete system using an algorithm based on a metric called category utility (CU), a measure how much information you gain by clustering.

Really, you only need to do two kinds of testing: Unit testing (to make sure that your individual components work) and end-to-end testing (to make sure your application works). Anything else is just a waste of your time.
Dr. James McCaffrey of Microsoft Research explains the k-means++ technique for data clustering, the process of grouping data items so that similar items are in the same cluster, for human examination to see if any interesting patterns have emerged or for software systems such as anomaly detection.

GraphQL gives clients who call your Web services the ability to specify what properties of your data objects they want. Here are two ways to let those clients also specify which data objects they want.
Dr. James McCaffrey of Microsoft Research uses code samples, a full C# program and screenshots to detail the ins and outs of kernal logistic regression, a machine learning technique that extends regular logistic regression -- used for binary classification -- to deal with data that is not linearly separable.

Some developers prefer to create applications with Microsoft's open-source Blazor tooling from within the open-source, cross-platform Visual Studio Code editor. Here are the top tools in the VS Code Marketplace for those folk, as measured by the number of installations.
VSM Senior Technical Editor Dr. James McCaffrey, of Microsoft Research, explains why inverting a matrix -- one of the more common tasks in data science and machine learning -- is difficult and presents code that you can use as-is, or as a starting point for custom matrix inversion scenarios.

A radial basis function network (RBF network) is a software system that's similar to a single hidden layer neural network, explains Dr. James McCaffrey of Microsoft Research, who uses a full C# code sample and screenshots to show how to train an RBF network classifier.

Resident data scientist Dr. James McCaffrey of Microsoft Research turns his attention to evolutionary optimization, using a full code download, screenshots and graphics to explain this machine learning technique used to train many types of models by modeling the biological processes of natural selection, evolution, and mutation.

Eric Vogel uses code samples and screenshots to demonstrate how to do Entity Framework Core migrations in a .NET Core application through the command line and in code.
Dr. James McCaffrey of Microsoft Research uses a full code program, examples and graphics to explain multi-class logistic regression, an extension technique that allows you to predict a class that can be one of three or more possible values, such as predicting the political leaning of a person (conservative, moderate, liberal) based on age, sex, annual income and so on.

I found a new use for Visual Studio Code, the little code editor that could: substituting for a vital work app when your PC dies and a replacement won't be shipped to your remote office for weeks.
A Red Hat developer has created the Didact project, a Visual Studio Code extension that puts the code editor to work as a tutorial guide and also showcases other things it can do via a combination of technologies.
GraphQL lets you create data access services without writing controllers. Instead of writing procedural code, you declare schemas describing what queries you'll accept and what you're willing to return. Here's how to get started in ASP.NET Core.
ASP.NET Core Version 3.1 adds some new features for managing events in Blazor. You may think you'll never need them, but there may be a time when you'll be glad to know about at least one of them.
ASP.NET Core Version 3.1 has at least two major changes that you'll want to take advantage of. Well, Peter thinks you will. Depending on your background, your response to one of them may be a resounding βmeh.β
