I am using SPARK 1.5.1, and I have DataFrame that looks like follow:
labelsCol, featureCol (Label1, Label2, Label 32), FeatureVector (Label1, Label10, Label16, Label30, Label48), FeatureVector ... (Label1, label 95), FeatureVector
The first column is the list of labels for that sample, and in total I have 100 label.
I would like to build a binary classifier for each label, so I want to transform the labels list column into a binary vector.
The binary vector will have a length of 100 and the value will be 0 or 1 depends on the existence of the label for sample.
Is there any strait forward solution for this?
