case class ScalaGMMFisherVectorEstimator(k: Int) extends Estimator[DenseMatrix[Float], DenseMatrix[Float]] with Product with Serializable

Trains a scala Fisher Vector implementation, via estimating a GMM by treating each column of the inputs as a separate DenseVector input to GaussianMixtureModelEstimator

TODO: Pending philosophical discussions on how to best make it so you can swap in GMM, KMeans++, etc. for Fisher Vectors. For now just hard-codes GMM here

k

Number of centers to estimate.
