An important library in the C# and F# open source communities is the Math.NET Numerics library. I blogged the first part in a (slow) series on using the library from F# back in June and there is another tutorial as part of the Numerical Libraries for F# and the .NET Framework overview from early last year. We also use this library in Expert F# 3.0, Chapter 10, in the chapter on "Programming With Numbers", and the library is also used in the new Try F# 3.0 website. The library has received a scrub recently,[...]

I am still working my way through “Machine Learning in Action”, converting the samples from Python to F#. I am currently in the middle of chapter 6, dedicated to Support Vector Machines, which has given me more trouble than the previous ones. This post will be sharing my current progress: the code I have so far is a working translation of the naïve SVM implementation, presented in the first half of the chapter. We’ll get to kernels, and the full Platt SMO algorithm in a later post – today will be solely di[...]

This time we are going to get into a little bit of code and produce the simplest of all 3d solids, the tetrahedron. I know its not the most exciting of things but we have to start somewhere. The scope of 3D graphics in computers is so vast that its very easy to get lost in the vast piles of research papers.

Just a quick note to say that I have made some minor changes to DynamoDb.SQL and released version 1.0.7 of the library to Nuget, here’s a list of the changes: fixed a bug with LIMIT when there is insufficient number of elements using the DynamoDBContext. added support for counting the number of matching items with [...]
