Get prediction list

[ecofee]

I am testing about document classification.
It return only single label.

I want to list of prediction with weight.
It would look like below,

public class DocumentPrediction 
{
  [ColumnName("PredictedLabel")]
  public string Label {get;set;}
  public float Weight {get;set;}
}
,
PredictionModel<DocumentData , List<DocumentPrediction>>

Is that possible with StochasticDualCoordinateAscentClassifier? How can I do that?
There is no ref about this.

Hi @ecofee ,

Seems like you want scores for all the classes. If that is the case add a column of type float[] and then add a ColumnName attribute on it called "Score", this will give you all the scores. To get scores to label names use TryGetScoreLabelNames as shown in the scenario example.

Thanks. But, There is no TryGetScoreLabelNames in ML.

.net framework 4.7.1
Microsoft.ML 0.1.0(Nuget)

Yes, it is not part of the current public nuget but will be part of the next one. In the meantime you can clone master branch and generate nuget locally to use this API. You can test this locally by doing the following:
build.cmd
build.cmd -buildPackages

Please delete the bin folder before doing this.

It helped me. Thanks again.

@ecofee you can also use the myget feed for daily nugets. Please let us know if we can close the issue. Thanks.
