Help us shape the future of deep learning in .NET
Deep learning is a subset of machine learning used for tasks such as image classification, object detection, and natural language processing. It uses algorithms known as neural networks to learn and make predictions on image, sound, or text data. Neural networks learn from experience, just like we do as humans. Similar to how we may try an activity and adjust our actions based on the outcome, these algorithms perform a task repeatedly and tweak various actions or variables each time to improve their results, making them very powerful and intelligent. We'd love to learn more about your current or prospective...

Originally Power Query was distributed as an Excel 2013 Add-In. However, as part of Excel 2016 it was natively integrated into Excel. Due to the dependency on .NET...
Work flow of diagnosing memory performance issues – Part 1
Work flow of diagnosing memory performance issues – Part 0 Work flow of diagnosing memory performance issues – Part 1 (this post) Work flow of diagnosing memory performance issues – Part 2 In this blog post I’ll talk a bit about contributing to PerfView and then continue with the GCStats analysis. You can skip to the analysis part directly if you like. One of the frustrating things for me when it comes to tooling is there are a lot of memory perf tools out there but very few are targeting the common types of customers I normally work with. Every tool does the basics; very few do intermediate and ...
Work flow of diagnosing memory performance issues – Part 0
Work flow of diagnosing memory performance issues – Part 0 (this post) Work flow of diagnosing memory performance issues – Part 1 Work flow of diagnosing memory performance issues – Part 2 I wanted to describe what I do to diagnose memory perf issues, or rather the common part of various work flows of doing such diagnostics. Diagnosing performance issues can take many forms because there’s no fixed steps you follow. But I’ll try to break it down into basic blocks that get invoked for a variety of diagnostics. This part is for beginners so if you've been doing memory perf analysis for a while you...
