After a long Easter holiday filled with late night coding sessions I find myself wide awake at 2am… good job I’ve still got my pluralsight subscription and a quick look at the Algorithms and Data Structures course again at least gave me something to do to relax the mind with some back-to-school style implementation of [...]

F# Data is a new library that gives you all you need to access data in F# 3.0. It implements type providers for WorldBank, Freebase and structured document formats (CSV, JSON and XML) as well as other helpers. This article introduces the library and gives a quick overview of its features.

Before getting started with Machine Learning in F# Interactive it’s best to prepare it for large datasets and external 64-bit libraries so you don’t get blindsided with strange errors when you happen to cross the line. The good news is it’s a simple process that should only take a few minutes. The first step is [...]

My trajectory through “Machine Learning in Action” is becoming more unpredictable as we go – this time, rather than completing our last episode on K-means clustering (we’ll get back to it later), I’ll make another jump directly to Chapter 14, which is dedicated to Singular Value Decomposition, and convert the example from Python to F#. The chapter illustrates how Singular Value Decomposition (or SVD in short) can be used to build a collaborative recommendation engine. We will follow the chapter pretty clos[...]

The F# community quote of the week was from Tomas Petricek in answer to a question on Twitter, see the pic on the right.  What Tomas says is not 100% technically accurate: you can get NRE in F# if you use C# libraries. C#-defined types and the "null" literal, or some backdoors like Unchecked.defaultof<_>. However what Tomas says does match people’s actual experience with the two languages, and it is certainly true that NREs almost never occur in routine F# coding. For example, this comparison records that [...]
