Does ML.Net support KNN?

I suggest adding the algorithm of this article to the function of time series.

Hi @sharpwood ,

Thanks for reaching out! We do not currently have an algorithm available for K-Nearest-Neighbors. I've added the KNN-with-dynamic-time-warping algorithm as a feature-request for time series.

(Leaving open until triaged.)

@rogancarr is the feature request on github? if so, could you please reference the issue here?

[rogancarr]

Sorry if that last post of mine wasn't clear. Let's treat this issue as the feature request.

I would very much like to see this as we're trying to port our facial recognition system from python/dlib/opencv/scikit to c#/dotnet/ml.net/dlib/opencv.

@rogancarr is it as simple as this?

Here is a sample dataset "Predicting Check Ins". It has 4 features, 8.9 million rows and 100,000 labels.
KNN would be good for this dataset, 100k labels is hard on most of the currently supported multi-class algo's.

not on our roadmap for near future.
