How to Update Members of a Collection with LINQ

Sometimes it's just cool to take a walk through some technology to find all the different ways you can solve a problem -- sort of "Fun with the .NET Framework." Here's a look at all the ways that Peter could think of to update an object in a collection ... some of which may be foolish.

How To Code Modern Neural Networks Using Python and NumPy

Data scientist Dr. James McCaffrey begins a series on presenting and explaining the most common modern techniques used for neural networks, for which over the past couple of years there have been many small but significant changes in the default techniques used.

How to Do Thompson Sampling Using Python

Suppose you have three different Internet advertising strategies and you want to determine which of them is the best as quickly as possible. Or suppose you work for a medical company and you want to determine which of three new drugs is the most effective. Resident data scientist Dr. James McCaffrey shows how Thompson Sampling can help.
