Sample for train/test sets in Deedle Frames
Supervised learning algorithms need a training set and a test set. This snippet show two ways to generate train/test sets. First is by count, where it will take a random number of rows from the Frame and generate two new frame of the specified size. This is useful if you have a very large dataset, but you only want to explore your learning algorithm on a small subset. Second is by ratio, this will break the frame into two parts based on the ratio given. For example you might want to train on 25% of your data, then test on the other 75%.

I use this basic template when writing .fsx files that I might want to compile. It adjusts the difference in command line/entrypoint handling between a script and a compiled assembly. This example shows the details for a WPF script — replace the #r's and/or remove the STAThread for a WinForms or Console script.

The Haskell const function
The const function is simple, but you can use it to make your code more legible. In this example we convert a unary function to a function of arity 2 (that ignores the second argument). Also by using the flip function from Haskell (which is equally easy to define) you can ignore the first argument.

version 1 is http://fssnip.net/62. This new version support convert from any existing function to a converter function by using composition and pipeline. The convert function is to make the function signature agree to the IValueConverter interface. You can add new functions in the FunctionLibrary module and reuse the class definition to reduce the coding effort. The first sample is to show how to make the converter pipeline work, the second one is a debugger converter used to debug the data binding problem.
