Update to the latest ML.NET 0.11.0-preview-27428-4.

The biggest issue to overcome was in BinaryClassification. Two trainers (Perceptron and Linear SVM) don't produce Probabilities, which means they aren't "calibrated" and can't get a evaluated as such. With that, it means their metrics don't produce Entropy.

Wow. This is impressive! Thank you very much!
Please give me some time to digest this...

@eerhardt Wat would be a good time to merge this PR? I'll probably wait for your next official NuGet packages (ML and DataView), right?

[eerhardt]

Yes, I think if you'd like to wait for v0.11, which will be coming this week. Once v0.11 has shipped officially on nuget.org, I can update this PR to that released version. Then you would be free to merge.

But please feel free to give PR feedback now. The v0.11 APIs won't be changing from the version I am using - it is the "RC" build of v0.11. So the only known change would be to update the version from the preview to 0.11.0.

Is the heat map OK in your project? I have a lot of NaN values in the input matrix (a lot in Fare and all of the Age values). Most of these values are correctly filled out in the data set.

It looks like the DataView does not react properly to missing values, or to the commas in the passenger name. But maybe I'm just running against an invalid combination of experimental NuGet packages (ML, DataView, CpuMath).

[eerhardt]

No, I don't think the heat map is OK:

Looks like the problem was that we switched AllowQuoting from defaulting to true to now default to false with dotnet/machinelearning@ec418e4.

I added AllowQuoting = true, and the map now looks like:

A build in Release mode fails with "ilc.exe exited with code 1200". Is that because your daily packages at https://dotnet.myget.org/feed/dotnet-core/package/nuget/Microsoft.ML are debug builds? Or am I'm missing something?

[eerhardt]

I'm not sure. I tried looking into it and saw that it was raising an OutOfMemory error during ilc.exe. The daily builds of ML.NET are Release builds.

[eerhardt]

@XamlBrewer - I verified this is the same behvaior as building in Release mode in the master branch. It doesn't appear to be caused by my changes.

Are you seeing it in the master branch?

[eerhardt]

@XamlBrewer - ML.NET v0.11.0 is now on nuget.org. I've pushed a commit to update to the released version.

When you create a new UWP project in Visual Studio and hook the new NuGet v0.11.0 ML.NET to it, you also get the ilc.exe fail on a Release build.
