class FastVectorAssembler extends Transformer with HasInputCols with HasOutputCol with DefaultParamsWritable

A fast vector assembler. The columns given must be ordered such that categorical columns come first (otherwise spark learners will give categorical attributes to the wrong index). Does not keep spurious numeric data which can significantly slow down computations when there are millions of columns.
