I am using Accord.NET in F# for the first time and I am having problems creating the function to calculate the distance for KNN.
Here is my code
static member RunKNN = let inputs = MachineLearningEngine.TrainingInputClass let outputs = MachineLearningEngine.TrainingOutputClass let knn = new KNearestNeighbors<int*int*int*int>(1,inputs,outputs,null) let input = 1,1,1,1 knn.Compute(input)
When I swap out the null for a function like this
let distanceFunction = fun (a:int,b:int,c:int,d:int) (e:int,f:int,g:int,h:int) (i:float) -> 0
I get an exception like this:
*Error 1 This expression was expected to have type System.Func<(int * int * int * int),(int * int * int * int),float> but here has type int * int * int * int -> int * int * int * int -> float -> int*
So far, the only article I found close to my problem is this one. Apparently, there is a problem with how F# and C# handle delegates?
I posted this same question on the Google group for Accord.NET here.
Thanks in advance
