…ng features from a DataFrame
I moved this functionality from TestFeatureBuilder to a top level FeatureBuilder as it can be quite powerful for very simple applications, in which there is a dataset/dataframe available and once would like to automatically create features from it.
Example usage:
case class MyClass(s: String, l: Long, label: Double)
val data: DataFrame = Seq(MyClass("blah1", 10, label = 2.0)).toDS.toDF()
val (label, Array(fs, fl)) = FeatureBuilder.fromDataFrame[RealNN](data, response = "label")
